[quote=J_Rho]I don't expect to be competitive with Vic this early in the season. If I can turn a time competitive with SS, I'll be totally stoked, since I never could do even that when driving the SM2 car.
I've got a lot of guesses about the changes I've made to the suspension settings, so in addition to the whole drivetrain changes, the handling could be messed up too. That's the good thing about Pros though - you get a bunch of runs and a couple tuning iterations in over the course of the weekend, so there's time to get the car dialed in and no "throwing away" the whole event with a bad Saturday.[/quote]

Interesting update from Jason following his outing at the El Toro Pro Solo:
[quote=J_Rho]So the last couple days have been interesting.
Put the car on the dyno Friday morning. At 20 pounds of boost, it made 400 ft-lbs. of torque at just over 3600rpm. However, there was a weird surge it was doing around 5 grand that we couldn't figure out. We figured it was ignition issues. It didn't manifest driving around on the street in first or second though, so I figured it was OK to race.
Friday afternoon I get the fender seams pounded and replaced the cap and rotor. Friday night, the car decides it doesn't want to start, no spark. Everything is diagnosed in ignition system, I even drive back to SD Friday night to get my known-good coil. Turns out it was the dreaded "MX Sync Test" problem a bunch of AEM EMS users get - when the motor is cold, I have to set the value to 9 to get the "Stat Sync'd" value to turn on; otherwise, the ignition won't fire at all. So to start the car cold right now, I have to fire up the laptop, get it connected to the EMS, crank the car with one hand, and with the other, change the MX Sync Test value from 9 to 8 once the ingition fires, while giving it throttle. The car will only fire the spark when cold with MX Sync Test at 9, but it won't run at that setting, so I have to immediately switch to 8. Weirdness. With the motor fully warmed up it starts with the value set to 8 no problem.
So I get this all figured out this morning and get the car tech'd. Saturday morning runs I'm getting a feel for the car, going a bit faster each run DNF'ing and redlighting along the way. My last right-side run is decent, a little bit faster than Navid, but dirty. Vic lays down some really quick scrathes in the 41.x range, but is also dirty.
For those runs I was launching the car with a bit of RPM and doing some crazy throttle modulation in first to try to get it to hook up. I don't think the ABS sensors liked that, and on my second run, I lose the ABS, which I notice when I lock up a tire horribly going into the turnaround - so basically, the morning runs were done without ABS, which I have come to depend upon quite a bit.
Afternoon runs went a bit better. I was a bit more comfortable with the car, and didn't really make any changes other than the spark plugs. The car was infinitely more fun to drive with the ABS, as it took away the fear of destroying the tires in every braking zone. Times dropped quite a bit from the morning, and were actually sorta competitive. I tried slipping the clutch at the start which seemed gentler on things, and didn't wack out the ABS. 60 foot time still sucked, though they weren't ungodly awful in comparison to the competition. Unfortunately, on my last run, which was quite a bit faster than my other left-side runs (and clean!), my radiator cracked in the crazy third-gear charge to the finish, which spewed water out of my hood vents and all over my windshield, making it impossible to see, or finish the run. In looking at the data, that was at least a low 42.x run, which would have actually put me in first (!) at the time. Oh well. I know I still need to be running about a second faster per side to be truly competitive (as Vic will likely show tomorrow if he can get the car working right), but for a first-time outing, and for those being my first 7 short runs in the car, I'm pretty happy, as there's still a bunch to do. I didn't make any changes to the suspension or shocks or pressures or anything, and treated today more as a test n' tune than a big race. I could have gone and got a Pep Boys radiator to run tomorrow but I would just end up replacing it next week anyway, so I'll just be taking tomorrw off from racing, and help out others.
The turbo response was good, perhaps not quite enough to be ideal, but not at all bad, and I found it pretty easy to modulate the car through a corner as boost built. Anti-lag should make it just about right. The top-end also could have been greater, but all in all I think it was pretty good. I guess I was spoiled by the SM2 Corvette that made >400wtq @2000rpm and never had to wait for the turbo. I might consider going for a C16-based tune in the low twenties in pounds of boost, see what the block can hold. The surface we ran on today was pretty grippy, and the courses relatively wide open, which are probably skewing my thoughts at the moment.
The 13qt cooler of ice was barely adequate for 4x40+ second runs. It didn't help that I had to spend a ton of time idling the car since I was worried I wouldn't be able to re-start it without the laptop hooked up. Morning runs had the water to just above ambient when done, and the afternoon runs, where I didn't idle as long and managed it better, had the water temp quite cool, but all the ice was still melted. I'll look at upgrading to the 19qt. version for the increased capacity.
Curiously, the car was only 2578lbs. at the afternoon impound weigh-in, only 18 pounds above my minimum. I was carrying at least 2-3 gallons more gas than I needed, meaning I'm probably marginally underweight already, and there's still a few things I can pull out. Basically, the extra cooler volume won't be hurting me any, weight-wise.
The diff (ATS carbon 1.5-way) worked great, no inside wheelspin at all. With the solid subframe bushings and the new diff, the rear make some disconcertingly awful sounds though. Guess I'll just have to get used to it.
Handling was surprisingly "close" to where it needed to be considering I'd guessed at so much. I can probably stand to lower the front a bit, which should help some things.
Anyway, to sum up, the 240 is, and can be, quite competitive in SM. I still have a bunch of work to do, but with some aero, more chassis/engine refinement, and of course a bunch more time in the car in it current trim, I think I can really give those SM guys a run for their $$$...
I'll show you guys some funny G-data of the car in SM trim vs. STS when I get back to my usual computers tomorrow...[/quote]

I was working left-side course this weekend while SM was running...J-Rho's car looked like it was absolutely CHARGING between the gates! Not sure what will happen on lower-grip surfaces (i.e. Topeka) but man it looked good out there...and I think both Vic and Navid have some new Atwater competition :D !
| j-rho | 03-26-2007 07:25 PM |
How did the car's acceleration look in comparison to the other SM/SM2 cars?
| PossumK | 03-26-2007 07:35 PM |
I worked the turnaround on the right course. It looked like there might've been some turbo lag (or throttle modulation?) before your strongest acceleration kicked in. But once your car was under full acceleration, it really moved. It looked to be at least on par with the other big SM cars like Vic's M3 and the SM STI. The two SM2 RX-7s were really flying around corners and keeping more speed, though, and appeared to have pretty smooth acceleration.
I wish I could've had my camcorder on a tripod at my station. The view was awesome.

Yeah, with only 7 runs in the brand new car, I'm still learning to trust the power coming out of the corners; when I got on the gas mid-way around the turnaround the boost was there, it was just me being a wuss with the gas pedal. Hopefully it was still a good show... :) Did the car lift a tire or anything?
My lowest speed through the turnaround was low 30's, I'll see if I can get Erik and Andy to tell me their turnaround minimums. I may have to move up to the big tires...:)

Everyone looked slow in the turnaround. IIRC, Sias' car even cut power there once (among the other places it failed over the weekend). It was the next section of the crossover and offsets where the RX-7s were really impressive.
I wasn't paying enough attention to the anyone's tires in the turnaround to notice if one lifted. I did see when your ABS failed and you were locking up your tires in several braking zones. I was wondering what the smoke from all four corners was.

I didn't notice it lifting any tires, at least not as noticably as the BMWs (inside front) or SM STI (inside rear).

[QUOTE=J_Rho]
Here's the SM vs. STS overlay - my good right side run at El Toro 2007 vs. my best right side run at Fontana 2006.

From earlier today:
[QUOTE=J_Rho]Hmmm, not too much going on. Needed some time off after the marathon of thrashing that I've had going on.
Bought 2 new radiators instead of just one, and just yesterday I swapped out the cracked one. I don't know exactly killed this one, whether it was age, being leaned on, too much pressure, or the cold pipe hitting it as the motor flexed. At least I have another spare now.
<aside>Does anybody make some SOLID motor mounts that get the motor REALLY low in the engine bay? The motor still moves, too much really, with the Cusco mounts I have now. Damnit.</aside>
I have room to run the front a ton lower now (~1") so I have to decide whether I want to make the leap and do the SPL FLCA's with the roll center adjusters and their bumpsteer spacers to fix the geometry that will start to get pretty messed up. I worry with a big offset on the bumpsteer spacers I might be taxing things a bit with 315's up front in a fast slalom. Depending on where the motor ends up I might try just raising the rack.
Funny stored related to this - at El Toro, I was having to adjust to the differences from STS to SM. After morning runs, 2 course workers independently came up to me to tell me how badly I was being beaten through the slalom on the way out. I decided to speed things up for the afternoon, and couldn't believe how quick the car would snake its way through there - data acquisition reported I was going [B]6 mph[/B] faster through the slalom in the afternoon. It was about as fast as I could physically turn the steering wheel, even with the HICAS rack.
I looked at my spare distributor and it's the same as the one that was already on the car. As I reported earlier, I was having the MX Sync Test/ S-Tooth weirdness/car won't start problem. AEM has acknowledged it here:
[URL="http://forum.aempower.com/forum/index.php/topic,16577.0.html"]http://forum.aempower.com/forum/index.php/topic,16577.0.html[/URL]
but from the looks of it, both of my distributors are the Mitsubishi type they haven't observed the problem with. I guess I"ll try changing the crank rising/falling edge stuff as they did, and hope it works, and hope that it fixes the weird surging issue the car had at 5000rpm on the dyno. I'd love to see this thing do a solid 20-21psi pull with some good gas.
I want to get the weight down a bit without spending too much $, so I'm going to a kart passenger seat and pulling out the last couple things I hadn't gotten to. Thanks to the people that have provided pics, either in this thread or privately, of some air/air IC setups that might work for me. I may end up going with a system like what Rob sent me. I just don't want to spend another grand on intercooling right now; if anybody out there, drag guys in particular (though it could work for anybody if they implemented another a radiator for the water), are looking for a good water/air system, let me know.
I'd like to get the car under 2500, so I can run a heavy fuel load for SM, and a light one for SM2. I think I can get to 2520 without touching the brakes, which I hesitate to do, as they work beautifully stock.
Once I get my to-do list (mostly odds and ends I'd rushed through before) done, and a couple more events under my belt, I'm looking at putting the car away in the trailer for a while, and using the garage space to start fabricating the new wing and splitter. The car should be quite good with those goodies installed...:)[/QUOTE]

[b]Update:[/b]
[quote=J_Rho]Thanks for the tip on the motor mounts. Google mostly came up with old for-sale ads for the JTO parts - if anybody out there has a set and would like to go to the softer Cusco or Nismo or old stock mounts (I have all 3), let me know, maybe we can trade.
The 315/30-18's are only 1/4" greater in radius than the 285/30-18's, so the car will only have to be raised that much to keep the tire off the chassis. In talking with a few other long-time SM'ers, I came under the impression that a little BFH work to sharply protruding seams was okay, even if inboard of the hub face. Of course, you'll have to take that information with a grain of salt and decide for yourself what to do with it; in any case, I suggest not doing anything questionable that couldn't be quickly un-done. With the 315's up front and the equal-diameter, 335's on the rear, the ABS should stay happier.
The brakes seemed okay for my second set of runs at El Toro with a more gentle launch technique. Actually, they were better than okay, they worked great, and I could rotate the car on the brakes on the way into a corner just beautifully, it reminded me of how well the car was working while on the brakes at the Pro Finale last year. I wouldn't want the bias tweaked in the slightest. I know I could save a bunch of weight for not a lot of $ with something like the ArizonaZcar brake system, I just hesitate to mess with something that's so important, and is working so well at the moment.
I haven't gone to the Z32 rear spindles yet because of the need to change the style of lower shock mount. It's definitely something I'm looking at doing next winter though. Unofficially and in my personal opinion, (I guess I should start saying that now, pretty sure I made it on the SMAC), I don't think the custom-forged/unrestricted material spindle/upright allowance will be staying forever in SM. Time will tell, but that's not a gamble I would do, and I would suggest others to wait on it as well. No question there's a ton of weight to be saved there. It'd be nice if somebody made a set of lightweight "drop spindles" like they make for old Mustangs with their crap front geometry.
As for the contribution of aero, it's very dependent on a few things, the first being the speed of the course, the sort of elements taken at higher speed, and the potential benefit through and past those elements. The El Toro Pro had a lot of high speed 60+mph stuff, and I think the aero would have helped quite a bit there, maybe as much as .3-.5 per side.
The other thing to keep in mind is that if you figure wings and splitters of a given area can produce a given amount of downforce, the lighter your car is, the more "valuable" that downforce is. A 2000lb. car is going to see a 7.5% increase in available normal force (and some % of that in overall grip increase) from 150lbs. of downforce, while a 3000lb. car is only going to see a 5% increase, and probably an even smaller % of that 5% in overall grip increase, since its tires probably already have a greater load per unit size.
You can then see why aero is so important to something like a 700lb. A-Mod car, where they make a whole lot more downforce than we can in SM.[/quote]

It'd be nice if somebody made a set of lightweight "drop spindles" like they make for old Mustangs with their crap front geometry.
As for the contribution of aero, it's very dependent on a few things, the first being the speed of the course, the sort of elements taken at higher speed, and the potential benefit through and past those elements. The El Toro Pro had a lot of high speed 60+mph stuff, and I think the aero would have helped quite a bit there, maybe as much as .3-.5 per side.
The other thing to keep in mind is that if you figure wings and splitters of a given area can produce a given amount of downforce, the lighter your car is, the more "valuable" that downforce is. A 2000lb. car is going to see a 7.5% increase in available normal force (and some % of that in overall grip increase) from 150lbs. of downforce, while a 3000lb. car is only going to see a 5% increase, and probably an even smaller % of that 5% in overall grip increase, since its tires probably already have a greater load per unit size.
You can then see why aero is so important to something like a 700lb. A-Mod car, where they make a whole lot more downforce than we can in SM.[/quote]

[B]Current suspension settings on the SM/SM2 240SX:[/B]
[quote=J_Rho]Front
Camber: -4 degrees
Caster: 6 degrees
Toe: 1/16" out
Rear
Camber: -2.25 degrees
Toe: 3/8" in
Wear/rollover based on these settings appears pretty good so far.[/quote]
[B]Update on car and design for his new Wing:[/B]
[quote=J_Rho]Well, the car is something of a beast now. Before, I could still sorta drive it around on the street, now I'd be arrested by the first cop that sees me. It's almost impossible to get going without spinning the tires, and the intercooler system is only good for about 2 minutes of fun before it needs a refill.
Basically, she's gone from a hotted-up but still approachable girl next door to a finicky and tarted-up supermodel, whose wild looks and prissy behavior are completely out of place everywhere except out on her runway, the autocross course. Fortunately, at least when she's out there, she really shines... I think the g-g graph I posted earlier says it all - the car has about 20% more cornering grip than it had before, and the acceleration more than doubled, to a point where even not running 100%, its straight-line ability is about on par with the SM2 RX7s I showed on the first page of this thread. Frankly, I'm very afraid of it from many angles - that something will catch fire, that a wheel will fall off, that the motor will grenade, or the flywheel will explode and cut off my legs, or that I'll hit full boost, lose control and slide 9000 yards into a hot dog stand, etc., etc. But that fear, the challenge, and the related excitement is part of what maintains my interest, and the worst fear of all - that the car would not be competitive (at least with the other 2WD cars) after all this work, is one that I've been fortunate enough to have already put to rest.
I had some ideas about a bunch more stuff to do to save weight and what not, but I'll be skipping that for this season. I'm going to focus on making it reliable with what I have now, with the only other major thing being the aero package. Down the road I'll probably want to convert to an air/air IC and upgrade the brakes and cooling systems to handle track-type usage, even though it won't be quite as good for autocross. Would be fun to be able to do a track day or try drifting or something. At this point I have just over 5 minutes of seat time in the car, with at least a couple hundred hours in prep work to get from STS to SM. I'm looking to improve that ratio a bit...
I'm going to try to have it back together in time for the May 5-6 event up in Atwater, see if it can hold together for a whole weekend, and if I can get it fine-tuned a bit from my rough first pass at things. Once I'm back from there, I'll start construction on the aero bits.

Latest update:
[quote=J_Rho]Nahh, didn't make the AAS event. I'm transitioning to a new job that starts in July, and from now until then, I'm sorta working both, which has killed play-with-the-car time. On the plus side, it should lead to a dramatic increase in available garage space in the near future.
I've managed to get the turbo pulled off, and re-attached a few of the fittings. I had done things in the wrong order before which compromised the tightness and seal of a couple, particularly the oil drain.
I replaced the cracked radiator and reinstalled a coolant loop that I had taken out, which may have contributed to the radiator exploding, I'm not sure. Changed the oil, the old stuff looked pretty awful for only 20 miles of driving and ~1 hour of idling - it smelled just like race gas actually, guess that's what happens when the A/F is <10:1 for a while.
Installed the spare distributor, and the car fired right up with my MX Sync test value at 8. I don't know if it was the warmer ambient temps or what, but I'm keeping my fingers crossed this one continues to behave.
What else...I lowered the front suspension about 3/4" from where it was before, bumped the front springs up 100lbs, and softened the front bar. Noticed the LF wheel bearing is shot now too. I'm hoping it's just a nasty coincidence, and it wasn't the big front tires bringing them to a rapid and murderous death. I quit working on it Sunday in the middle of changing out that bearing - once that's done, and the suspension is all put back together, I'll just need to reset the ignition timing, and it should be set to go.
Oh, and the foam cores for my wing just finished being cut, so the wing is starting to take shape, literally.
Setup has been funny to watch, and educational insofar as it clearly illustrates how twisted and unrealistic Hollywood and "reality tv" is these days.[/quote][url]http://forums2.freshalloy.com/showthread.php?t=163184&page=6[/url]

Hey Jason,
Watching the show has been pretty fun for me, though it's almost overshadowed by the entertainment value of everyone's reaction to it. Great to see you and Matt pull that one out in the most recent episode! Does that mean as a reward, you got to have your way with one of the Sketchers girls? :devil:
Even though Jeff and I chose the path of early exit, I'm still stoked for all you guys, and wish everyone the best.

Bill[/QUOTE]I agree, it wasn't/isn't there yet. The thing to understand is that cars like this are organic creatures, ever growing, changing, adjusting - they will never be "dialed in" and left alone in the way in which you're probably thinking. Refer to Andy McKee's for sale post of his SM2 car for his experiences as well.
I was quite happy with the way the car was at El Toro, but the question is, and will always be, "might I be happier if I changed x,y, and/or z?". People that like building and tuning cars will never really completely settle on a setup, regardless of how long they've had a car. Plus there's always course/surface variations to try to tune for, and the higher likelihood of part failure/breakage.
The changes I've made may sound like a lot, but to me, in total, they're no more drastic than a little twist of a shock knob. The wing and aero stuff will be a bit bigger, but that's still a little ways off.

[quote=J_Rho]The car will get its second running this weekend at El Toro. I got talked into instructing at the Evolution School on Saturday - I'm hoping to get a few runs in then, and have all day Sunday to test and tune. I think we'll be re-using the ProSolo course, which will be illuminating to compare sector times of then vs. now.
Moved the AEM to the glovebox, so there's no longer a big mess of wires and crap dangling in the passenger footwell. Also wired in 8 new inputs to the DL1 data acquisition system, so in sync with acceleration and GPS-based speed and position, I'll be monitoring:
Throttle Position
Air/fuel ratio
Load (boost)
Intake air temp
Coolant temp
Knock
RPM
Vehicle Speed Sensor reading (VSS)
Since autocrossers are too busy to be looking at gauges much during a run, I can look at that stuff afterwards to make sure nothing bad is happening. In particular, I'm curious to see how well IAT's are maintained at high RPM, if the little intercooler is keeping up. I'll also be looking at the accuracy and consistency of the VSS data to see how useful it'll be for use in traction control or anti-lag functions.
I'm going to try and get some video going too if I can, though autocross video tends to kinda suck. It'll at least show how busy things are to those not familiar with it.
...
As for aero, I have the cut foam cores for my new wing in hand. I've been hot-wiring some smaller foam pieces and playing around with a composites starter kit from Aircraft Spruce, trying to decide if I want to try to skin them myself in carbon, or pay to have someone else do it. In either case, I'll be leaving the car in the trailer for a while after this weekend, which will free up some garage space to build the wing.[/quote]

Pretty sucky video, but this is the first I have of the car in action. If somebody wants to host it in higher res, I have a better 25MB version.
Got a chance to take 2 runs on a slight makeover of the El Toro ProSolo's left course. They had just set it up in advance of the practice tomorrow, so it was dirty and covered with tons of little pebbles. Cold tires too, so don't take this as any sort of suggestion of how to drive, and for those of you who already know how to drive well, cut me some slack please..
The motor felt quite strong, perhaps it was the cooler air. Having trouble getting the DL1 data off my CF card (left the reader at home), but I can't wait to see how everyhing was holding up in the engine bay.
I'm going to walk the course in the morning to see how dirty it really was - if it was pretty clean, I'm going to lower the rear a little bit and maybe make a small shock adjustment. If it's visibly quite dirty, I'll probably just leave it alone and try to run later when it's been cleaned up a bit.
Car feels good, but I need a wing mang![/quote]
[quote=J_Rho]Here's a couple more from yesterday. The course got cleaned up nicely and got a lot better over the span of the day. Here's me driving, my quickest clean run: [url]http://www.youtube.com/watch?v=u7C6VhLZ1pA[/url]

Not sure if you're still planning on this setup, but a ten point cage will not be legal for SM. As per the GCR, you are limited to 8 points. Also, unless you've completed your engine swap using the stock subframe, not a WRX unit, you'll have to play in XP anyways.

I fall into this class because of my original engine swap but want to play in this class as coming from FSAE much else is really technically and spec wise boring to build and drive.
only problem is the weight discrepancy between my NHRA minimum weight and the SM minimum.

yeah, I know...also if you removed more than 1 pound (IIRC) from your front bumper beam for your FMIC install you are SM illegal too... ;)
NHRA makes me run an 8 point, so I'll be good...the old x-member will be going back in too with a new manifold

dumb ?, but are you allowed to remove the OEM steering wheel and replace it with a different one? It was my understanding that if the vehicle had an airbag equipped steering wheel you couldn't remove it?
I ask this because it looks like a non-Oem steering wheel in the videos.

[QUOTE=Homemade WRX;16912059]only problem is the weight discrepancy between my NHRA minimum weight and the SM minimum.
2560 for SCCA and 2900!!! for nhra (I will fall under this in complete stock trim with 10 point cage):eek:
so I have to add weight to my car for nhra and then remove a quick 340 for autocross:rolleyes:
should be an amusing process to make easily do'able (inherently lazy ;))[/QUOTE]
I thought you were doing a 3.0L h6? If that is the case and it's turbo'd your minimum SM weight would be 3010 lbs. They changed the SM weight rules for this year. :(
Just run in XP with whatever it weighs and you are set. :)

That is a stock and ST class rule only. I'm pretty sure the 240 j-rho is using didn't come with a drivers airbag anyhow.

| j-rho | 06-07-2007 03:06 PM |
Yeah, the stupid ST airbag rule is one of the reasons I built an earlier (S13 chassis) 240, instead of the newer, 95-98 S14 chassis, which all came with airbags. The S14 is stiffer and has room for more tire without being much heavier, making it a better starting point for an SM ride. The 97-98's are quite a bit better looking too, IMO...
| Pacobeagle | 06-07-2007 05:05 PM |
AHHh, i agree with you on the fact that it's a dumb rule. Technically, could we disect the thing? I mean, it can look like an airbag....it doesn't say it has to be functional, right?

[quote=J_Rho]The engine did quite well. The intercooler worked great, the highest manifold air temp the car saw was 152 degrees. The traces of throttle position and MAP sensor voltages are almost completely in sync - meaning, boost comes in just as quickly as I can roll into the gas without blowing away the tires. Works great and drives *almost* like a large displacement NA motor.
I noticed a couple little things that could use work with the tune, but nothing huge. At this point the biggest gains I have left to make are in aero, basic suspension tuning, and just getting used to the car. In reviewing the video and data logs, I am clearly suffering from a bad case of "throttle greed". :D
Part of what was neat about this practice is that it was held using the exact same course as we used at the ProSolo (with a minor tweak to the start area). Because of this, I was able to overlay sector times from the Pro in March to the runs I took just a few days ago, and figure what sort of time I "could have" run. I can also compare grip levels by looking at the g-g circle between the two days.
Even though the grip was ultimately lower last weekend (due to tire age, or course cleanliness, or whatever), I found I left over 2.5 seconds "out there" on the left hand side at the Pro. So that would have put me at about a half second back from McKee's quick left side time in SM2. Not too bad I suppose, figuring there were at least a few tenths out there on this very fast course with some aero mods.[/quote]
[quote=J_Rho]Well, not everything obvious, is obvious to everyone.
I would say with an SR you'd probably need a GT28RS to match the kind of response I am getting now, along with the ultra-short charge piping and good tune. If Garrett does a twin-scroll GT2871R, that might work also.
Another option the SR guys have is to build their motors to rev reliably to 8500+rpm. With a change to final drive ratio, the car could be kept in the 4500-8500 range (whereas my KA works mostly in 3000-7000) which would make something like the "regular" GT2871R a viable option.
The more boost you run the bigger "hill" you have to climb each time you go back to the gas. Counting more on displacement and less on boost helps here. Of course, there's always anti-lag too, which I have yet to experiment with.
Here's another high-res run, my quick time for the day, but dirty. I had a real hard time getting my braking point correct in the fast third gear section. I don't know if it was inconsistent brake vacuum from going so quickly from full throttle to full brake or what, but this time I broke too soon, as opposed to too early in the video above.

[quote=J_Rho]Still don't have any action shots unfortunately, but here's one from last Sunday:
[img]http://www.jrho.com/sm240/sm240eltoro.JPG[/img][/quote]
[quote=J_Rho]Hard to say at this point. The two class options I have are SM and SM2. The fastest SM2 car ran a 40.1 lap on that course; my car did about a 40.7-40.8. The fastest SM car ran a 41.4, but broke on Saturday and didn't get to run Sunday, where it likely would have gone a bunch faster (going to guess a 40.5-40.6). Fortunately those comparison times are representative of top-flight efforts, as both those drivers are 2-time National Champions in their respective classes (Andy McKee in SM2, Vic Sias in SM).
The 240 was understeering a bit that day, was a bit overweight with a full tank of gas, and didn't have the benefit of aero. I think there were definitely a few tenths left in car development, and also a few left on the table in the driving dept. Part of what I like about this "Street Modified" category is that there are lots of rocks to look under to uncover those last few hundredths, and to me anyway, the car's ultimate potential is still mostly unknown.
My goal is to be as close to the SM2 RX7's as I can, in case I decide to run that class at the National Championships (for reasons I discussed at the bottom of my original post in this thread). The only innate advantage their cars have over me are a better chassis (front suspension, CG height and location), but they also have much more development, and at this point, much better drivers. Fortunately for me, the two people campaigning the FD's also have some compromises I don't - Andy McKee is a Kumho contract driver, and their tires are likely not as good as Hoosiers at Heartland Park; Erik Strelneiks is on Hoosiers, but the 3-rotor RX7 he's driving is actually his wife's car, and they don't want to cut up the fenders, so he's running some relatively narrow wheels - also because of the 3-rotor, it's also about 150lbs. heavier than mine and Andy's cars (heavier because the rules say it must be, not because the motor is that much heavier).
I think my car will continue to get better as we march towards September. At this point I give myself about a 1/10 shot at winning, 50/50 shot at top 3, and about 85% probability of top 5. This is assuming things progress as I envision they will and the weather is dry and consistent for all class participants. Results in our championships are all too often decided by the weatherman...[/quote]
[quote=J_Rho]PJ, if for any reason you can't get your car together, or sorted as well as you'd like, in time for Nats, I am going to need a tire warm....errrr...codriver...
Those guesses were for SM. With Bob Tunnel gone to XP, that leaves Daddio and Sias as the two guys that will most likely beat me, but gives me a good chance (50/50 I'd guess) at third. Who knows though, anything can happen, there are probably a lot of really pissed off SM competitors who'll read this and think I'm dissing them, which I don't mean to. Oh well.
I'd say my chances are similar for SM2, except maybe 1/20 chance of winning (since both Andy and Erik would have to have REALLY bad days), but because of the lack of depth to the class, I'd say the chances of coming in third are very good more like 60+%. I was third in SM2 in 2005, and I know I'll be faster this year in my car than I was in '05 in Gary's car, and nobody so far has shown up on the radar in SM2. There are a couple cars out there that could though... guess we'll just have to wait and see what the weatherman brings us...[/quote]

If you're 7 seconds back in Solo, I hate to break it to you but the majority of that is NOT the car. I'd flip that and say 5 seconds are driver, 2 seconds is car. Even that is probably being quite generous. STS class winner at the Devens tour was only 3 seconds back from the SM class winner (looking at sunday only, since STS ran in the wet on Sat.) So unless you've got an FSP car on street tires running in SM, it ain't the car. ;)

7 seconds is definitely a huge gap - however, it could be more than 2 seconds due to the car depending on his level of prep. Heck [B]if[/B] he's on the stock suspension with re92's with an n/a 2.5L swap, he could basically be driving an HS car on street tires in SM! :eek:

Wow, I have to explain myself... :rolleyes: Its closer to Chiketkd's idea though, so i'll go into more detail...
Heres the results: [url]http://www.sfrscca.org/solo2/Sacramento/Results/2007/Cup/round6.html[/url]
I'm there at #10 in SM. Every car ahead of my time in SM was on race tires and had 75-100 or more HP on me (that integra was turbo'ed) and almost all of them are every-event regulars at Auto-x'ing... I've only been out about twice a year the past 3 years.
And yes, im on street tires (225 hankooks) with ~175hp, but a good suspension setup (but not calibrated or aligned well) and STOCK brakes... I just upgraded my brakes this last weekend, didnt get to use them then :(
If you want a good car comparison, look at John Hancocks time in DSP, he has the same coilovers (megans) and roughly the same HP I do (he has an RS ) but is on race slicks (245's) and goes to every even and has won every event. His 62.8 vs. my 65.08... My 3rd run, the 66, was with a completely blown corner (had to stop completely, went in way too hot and locked it up) would have been a 64 for sure, but I dont really care cause I'm not out there to win anything.
Steve Nguyen is one of the best drivers in that class, he's at every event and i've seen him there in that GTI (previously an old-school Sentra SE-R) for 6 years or so out there racing every event, he could hop in the Sias-mobile and be within a couple tenths of their times, but his 61 vs. Sias's 57 gives you a good idea of the car discrepancy in a class that takes BIG money to compete in...

And yes, im on street tires (225 hankooks) with ~175hp, but a good suspension setup (but not calibrated or aligned well) and STOCK brakes... I just upgraded my brakes this last weekend, didnt get to use them then :(
If you want a good car comparison, look at John Hancocks time in DSP, he has the same coilovers (megans) and roughly the same HP I do (he has an RS ) but is on race slicks (245's) and goes to every even and has won every event. His 62.8 vs. my 65.08... My 3rd run, the 66, was with a completely blown corner (had to stop completely, went in way too hot and locked it up) would have been a 64 for sure, but I dont really care cause I'm not out there to win anything.
Steve Nguyen is one of the best drivers in that class, he's at every event and i've seen him there in that GTI (previously an old-school Sentra SE-R) for 6 years or so out there racing every event, he could hop in the Sias-mobile and be within a couple tenths of their times, but his 61 vs. Sias's 57 gives you a good idea of the car discrepancy in a class that takes BIG money to compete in...

No need to defend yourself. I automatically assume people are at least bringing the majority of the hardware to an event. I forget that sometimes people show up in very underprepped cars for whatever class they are in.

At least he's running in the right class. Given how folks like to run whatever class they are closest to in time rather than the class that they fall under, I have go give applause for him doing it the right way. :)

Ya, i'm running in the right class... Sucks though, If I had an RS and not a swaped L, i'd still be in ST-S or ST-X :(
I'm curious though, I havent looked into it... According to the update/backdate rules, can an 02-05 WRX run with an 06-07 WRX engine for ST-X/U?

Hardly anyone in the lower end/stock classes shows up with COMPLETELY prepped cars around here... Especially at this charity even which has lots of new folks and folks from the area (since its the only one physically here in Sac the whole year) who don't have prepped cars out just for fun.
The usual attendance for Sac SCCA events is like 100-150 cars, but that weekend it was over 200...

I'm one of those horribly out of class cars too...just because I'd been spoiled and always drove the FSAE car...
time to get to working on mine now...school is done ;)

No. There's no update/backdate allowance for the ST* classes. You can swap engines between WRX model years in ESP though... ;)

So, the explanation-
It's not that I don't think this has the potential to win - it can - I am as confident of that today as I was of the car's potential in STS at this same time last year. It's lighter than the M3s, narrower, has at least as much power, and a much shorter wheelbase. This year is going to be tough against Daddio in his Evo, but from what I hear the grip levels at HPT are coming up so it won't be as hard for the 2wd cars as everyone thought.
As you guys may know, the designing and building part is what I enjoy, and that part is all but done. This car handles, brakes, and especially, accelerates, like a great dream that I've made come true. Even if the new owner never changed a thing, they'd have an awesome machine capable of an easy TTOD (amongst cars) in just about any SCCA region in the nation. To be at the very top of Street Modified though, in addition to exception driving, you have to be constantly working and tuning and tweaking the car looking for those last few hundredths, and with a recent job/career change, I don't have the time to do this car justice any more.
Everything on the car is still practically brand new, you could probably part most of it out, keep the stuff you like, and still make money with my asking price. Hopefully the buyer keeps it together and puts it to use in his/her chosen field though - besides autocross, I think it would totally kick ass at drifting, road racing, or even drag.
If you guys have any questions, please feel free to ask them here or in the for-sale thread. You can also contact me at [email][email�protected][/email][/quote]
