Man, that car is fast, and with a 9K rpm limit no wonder!!!!

I dont ssee anyone beating him at Nats. It is a very quick car. No offense to the OP, I love you car. I am also in SM, but with an 03, I have no hope.
Pacobeagle 08-10-2006 08:04 AM

Well, I can tell you this. One day I will or damned sure come close.
skuttledude 08-10-2006 09:03 AM

Thanks for the link.

Damn that guy is quick. I've been waiting for his videos for awhile.
DrBiggly 08-10-2006 09:59 AM

Most autox runs look slow on video and if his looks that fast on video I can only imagine how quick that monster is in person. :)

.... and he's seriously smooth.
rupertberr 08-10-2006 10:41 AM

Vic's real good but I like Steve's post run comments best. :devil: :lol:

Rode along with Bob Tunnell in his M3 once, he is not too far behind Vic. That was pretty impressive too.
Pacobeagle 08-10-2006 10:48 AM

If you watch the second driver in the BMW, you'll notice that the throttle inputs are abrupt and that can upset the suspension on the car. Also, his steering inputs compared to that of Vic's aren't as smooth.
I think to compete against that kind of power is tough yes. But build the right motor and gear it accordingly and I think it can work. Remember he's at 13.5:1 CR plus a 9k rpm limit. That simply equals, response vs a turbo car. AND, he'll out last you in the gear. I figure he's in the 500hp mark.

SO, I have to come up with a similar setup or be ultra smooth. The question is, how do I acheive a similar power level and still have a super responsive motor. The boxer unfortunately doesn't take kind to high compression. I think 9:1 is about it.

Comments? I was thinking 9:1CR, a 16G Evo iii turbo and my current Sti-Ra gearset. Possibly just the Sti gearset.
DrBiggly 08-10-2006 11:04 AM

-Whatever you need to do to the engine to give it quick response, whether that be a 2.7L stroker or a 2.5L STi setup.
-Use stock headers that have been honed out and coated for fastest throttle response.
-APS-style turboback, no cat obviously. Coated. Again, throttle response.
-Some form of anti-lag programmed in for when you lift. Dead serious.
-Obviously a quick spooling turbo that gives you just enough power.
-Dunno about the gearset; you'd have to find optimal for your speeds and driving I think
-If the 2.7L Stroker or whatever interferes with rev range and short gearing, compensate in some area to maximize for what you need as a top end. Or just be like an STi and assume you're going to 3rd on most courses and shorten the gearing even further for a snappier 3rd gear.

-Biggly[/QUOTE]

you have no idea.... :( Take your best run [i]ever[/i] and then take away 2 - 3 seconds, and that is how fast Vic really is....

I can get close to him on the first and second runs, even beat him. But once he gets heat in his tires, it's all over.

I think this year in the NATs with the new surface, AWD may have a slight advantage until the surface is properly broken in. If you have not beaten Vic by that point, it's all over.

FWIW: I compete against Vic in SM in the SFR events when he shows up.

that's all fine and dandy, but if that 2.7 is not reliable, forget it. That is what makes Vic's car so impressive.

IMHO, I don't know if the 2.7 is really worth it. you can get plenty of torque out of the 2.5, epecially with anti-lag.

don't forget that you also need to over-rev that engine. If you can't bring it up to 8500 or 9000, pack it up and go home... Vic's biggest advantage is not having to shift as much. To that end, if I still had my STI, I would concentrate on changing the gearing in the tranny or changing the ring and pinion gears, that's killing you in autox right now with the 6-speed.

Mhyrr 08-10-2006 11:44 AM

Tunnell coned away the win over him at Packwood. Both SM (Tunnell vs. Sias) and SM2 (McKee vs. Strelnieks vs. Popp) are going to be unbelievable to watch.

I still think SS is going to be the biggest dogfight. Braun (Elise) vs. Salerno (Elise) vs. Stewart (GT3) vs. Thomason (supposedly GT3).
grippgoat 08-10-2006 11:46 AM

[QUOTE=Pacobeagle1]The question is, how do I acheive a similar power level and still have a super responsive motor.[/QUOTE]

I would think higher RPMs would be the first place to look.

And wouldn't water or alcohol injection let you run more timing / compression / leaner AFRs, all of which would improve response and power?

I haven't heard it mentioned in a couple years, but GP Moto's twin scroll turbo setup was supposed to give big power and response. I don't know whatever happened to it.

Mhyrr 08-10-2006 11:54 AM

[QUOTE=ChrisW]Vic's biggest advantage is not having to shift as much.[/QUOTE]

er.. that's not his biggest advantage. Did he build it so he wouldn't have to shift? Of course, but that's a very minor part of the equation. WRT to gearing it's being able to have an engine that produces good torque over a ridiculous range, with an amazing (compared to a street car) torque multiplier. That's why he went from a blown 3.0 to the S54 (and it's why Honda's work well..), at the same time he went from a 3.38 final drive to a 4.10!!

His biggest advantage? Hmm.. it might be the 315/335 tires.. or the 2610 lb weight of the car.. or the custom triple adjustables.. or the other custom suspension pieces (drop spindles).. or the aero.. or that its one of only very few true SM cars out there.. OR the loose nut behind the wheel.

FWIW, I do think a Subaru could compete.. but I'd start with a lighter chassis, add lots of STI bits and go from there.. Think Stompy minus 400 lbs and possibly with a better suspension (and more power/gearing).

The car Phil B. was building :) . I haven't heard anything from him in a while but the car you're describing is the car he was at least part way through building. '95 Impreza L body with 2.5 block and RA Spec-C heads, custom turbo and big old tires.

For those who are in the CA area and get to see Vic's M3 more often than once a year at Nationals I'm curious on how the damage from the CV failure at last years Nationals was repaired. Didn't get a real long or good look at the carnage but did help to get the car off course and onto the trailer and could see what looked like damage to the unibody that I don't know of an SM legal way to repair.
Draken 08-10-2006 01:13 PM

I never paid attention to the repairs. But I was working the scales when SM was weighed. And for FWIW, Vic's car is not at the minimum weight, and the corner balancing was way off. He just sorted shrugged his shoulders and smiled, like he knew he still had some room to improve. In fact, he wasn't the lightest nor best balanced SM M3 at Atwater.

Mhyrr 08-10-2006 01:24 PM

Yeah, I've been anxious to see Phil's car run for awhile now. Eric Stemler's too for that matter.

Vic's car is a great 50/50 car. Looks awesome from 50 feet away doing 50 mph. Up close, gaps are big, paint chipped, tape torn, fiberglass edges rough. It also sounds like ass when it is idling (trying to idle) next to you in grid, and you know it has some compression, as the starter motor works hard to turn it over.

Exactly why I put "or 2.5L motor" in my first line. Would the greater displacement make for better throttle response? I have no idea whether it would be more beneficial or only lightly beneficial. Hence why I said what I did. If it's feasible to get the greater displacement without sacrificing some other area of performance that could be a hindrance, go for it. Otherwise fix other issues. :)

Hey thats Ron Bauer annoucing. Yeah Tunnell had Vic last weekend, but he couldnt keep it clean. Is Daddio still running his Evo, he might have a shot. Remeber he injured himself at Nationals and he was still the top finishing AWD car.

I was lining up with the SM guys last weekend. I was hoping for Sean or Vic but I lined up with Navid. Both those cars are awesome. SM is going to be deep this weekend, should be fun to watch.

adhowe70 08-10-2006 07:31 PM

And when Andy McKee drives the car, he's even faster than Vic! I bought McKee's S2000 (and had some success with it) and was shamed when I had Andy take a run in it. He had taken a couple runs in his RX-7 before it broke then took one run in the S2000. Andy was a full second faster than I was after 5 runs in the car. I went on to finish 5th at Nationals a few weeks later, so I wasn't a slouch in the car at that time... Andy's just that stinking fast!

I had the pleasure of competing against Vic and company last weekend... based on what I've seen this season, Vic's car is faster than the best SM2 cars in the country right now.

My Subie was just over 2600 pounds on the scales at the Pro last weekend. Now if we can just the the effing engine running right... Argh! I still have a long way to go, but I think I've got the best shot of anyone in a Subie. Light chassis, boatload of torque, no lag.

Max's, BlkWRXWag, STU STI beating Vic's car at the Atwater ProSolo SuperChallenge. Vic's car being driven by co-driver Sean Boyle. Vic's car was 3 seconds faster then Max's STI, on a 30+ second course. :eek: But, considering it's huge R tires and + power ... props to STI's! I'd love to see a max'ed out SM STI ...

It would be so completely outclassed, you'd be depressed by it.

If the proposed minimum weight rule goes through for 2007, STi's will need to weigh a minimum of 2872 pounds. Vic's M3 will still weigh 2600 pounds or so. You just can't make up that kind of weight penalty.

On the other hand, I'll still be competing at 2625 pounds. :D And ballasting up to get there.

Not to take away from Max, but his win on that run didn't have much to do with him driving an STi against Sean, or "beating" Vics car.

The win of the challenge round comes down to the dial in of the class. Since Sean was .6 back from Vic, Sean has run *Vics* dial in. Since Maxs STi was 1st in STU, he only has his own dial-in to run against, which means Max should be closer to his own dial-in than Sean to Vics. It's a good situation for Max to be in as long as he doesn't mess up since he statistically has a lead going into the challenge.

Unless the 2nd place driver in the class sandbagged, or coned fastest run and still got in, it's a good situation to be in if you're class winner going against a 2nd place driver for a round. :)

BlkWRXWag 08-11-2006 10:49 AM

You're quite right KC. I beat Sean narrowly and it was a good situation for me.

However, it was pretty scary launching, and then hearing what sounded like a rocket launching behind me. Definitely one of the most exciting races I have ever been in:D

IIRC, despite being injured... didn't he have the fastest dry time on the 2nd day?
Pacobeagle 08-12-2006 09:29 AM

So, what's being said is that a WRX won't make it as an SM car(competetively?) Then what class would the WRX be a threat? My car, currently, is an SM car. My mods list puts me there. I'm still trying to get the car to weight, more power, better handling. The car does well locally. I know it's not a Nationals car though. That, I think, will take another year or two of mods, building, tuning.

daddio tore a tendon in his left leg the day before competition. he could barely walk. he also lfb's, and had his leg tightly wrapped so it couldn't move. he did have top time in the dry, but vic's car broke in the morning, tunnel's car overheated with both him and vic driving it, and both vic and bob took their final runs in different cars. iirc, bob took his last run in daddio's car.

daddio hasn't finished doing everything he can with his car. it pulls some incredible numbers though, numbers that the bmw's can't touch. on the new surface, expect daddio to be at the front. of course, rumor has it that daddio won't be at nationals this year.
mjautoxer 08-12-2006 11:34 AM

Well I will confirm the rumor that I will not be at Nationals this year.(First time since 1988) It has been a goal of mine for some time to get into a Pro road race series(World Challange, Grand am, etc.) I came to the conclusion that if that is where I want to be, I needed to free up my schedule and start doing events that may have a chance of getting me there. So I decided that I would not plan on running any autocrosses this year, and see what type of track stuff I could get into. I have recently hooked up with AMS motorsports out of Chicago, and have driven a few time attack events for them. I will miss being at nationals, but I feel that I needed to make myself available should any opportunities come along.

As far as a awd car running with Vic in sm, the answer is that it absolutely can. My car was nowhere near the prep level of Vic's last year. I drove poorly the first day, compounded by coning away my last two runs in drying conditions. I am not saying that I would have beaten Vic, but it would have been close. That coupled with the fact that nationals will be on asphalt this year gives the awd crowd a big advantage in my opinion. My car weighed 2960 without me in it at nationals last year. A better center diff controller, 200 lbs of weight off the car would make a huge difference. I had no splitter on the car either. In the end it will be an awd car that will be dominant in sm.

I don't know if they care locally where you race, but i don' t think the fender braces are SM legal.

Did you notice an actual improvement from using those fender braces? I'm curious as to feedback on them. :)

that is an awesome course...
locally we have a small lot (busted old concrete air strip) and a big lot (smooth huge concrete hover craft lot)...they are vastly different to drive in a subie...and in the formula car will we top out on both courses, so it doesn't care ;)
