Ultimate SM STi turbocharger?
�
�
Hey guys,
Im trying to run through the list of turbos that would make better sense than the 3" Green I currently have on the car.
1. GT32 twinscroll (w/ewg)
2. TD06H-18g (w/ewg)
3. TD05H-18g (w/ewg)
4. ?
I have every peripheral mod known to man... so who has done well nationally with an aftermarket turbo?
thanks,
Chris

I am not aware of any nationally competitive SM STis, but what about something like a VF37 twinscroll set-up (maybe turned into a PE1825)?
| shikataganai | 09-11-2006 09:32 PM |
uh, just the VF39? low end grunt is more important than top end pull imo...
| BHawk | 09-11-2006 09:36 PM |
You could run a single VNT turbo if you had enough cash to dump into it.

Why VF37 when you can VF42?

why any of that when you could do VF34, water injection, C16, big air/water and call it a day.
| SPOOLN | 09-12-2006 06:51 AM |
I use a VF34 in SM. I think there are better options out there, especially now.

Chris Fleming uses a Garrett GT-series turbo, I'm not sure which one though...

I'm using the Deadbolt SZ49 with a Spearco Top Mount and all the necessary supporting mods on a stock block. The car has virtually no lag with the top mount and pulls HARD all the way to redline. Another good option for autocrossing would be the 20G.
Unfortunately I won't be at Nationals so I won't get to see how much time I made up against the top runners in SM. I finished 20th out of 38 competitors last year at Nationals still running the stock turbo.

I was shooting for the smallest(quickest spooling) turbo that would give 375 awhp. Does anyone know enough about the VF42 to say there is a real difference? How about availability?

Yeah, the stock turbo is actually THAT bad for SM. I'll look into what a VF42 is.
I called the folks that do the "HotSubaru" thing above, and they claim its a GT35. Personally, I would have a hard time coming up with a *worse* turbo for AutoX... but what do I know ;)

Great thread! I'm trying to figue out what to do for next year. I love my STi but the SM pax kills me. I'm thinking about getting a mr2, crx, miatia or something else for next year. I think I'll start a new thread for STi SM set-ups. To see what everyone else is running.

That car is a beast by the way. It's making 440whp if I remember right. And I've seen it destroy the competition at a few local autocrosses. I have no idea how they would do at nationals though.

id go the other route and run a bigger turbo with good top end and just run anti-lag...if you can find one that would tolerate it.

Spooln--Yup I like the VF22 alot but it dies on the top. I must say that with my Sti-Ra gearset the thing is a blast to drive. I've won every event I've been to this year including two FTD's. Of course the FTD's were a result of my CCW's(17x10) being able to put more of the 275's down vs the Rota's(17x8.5) I had previous.

I had the Perrin 30R with the .63ar on my STI when I auto-x'ed it. I was running a UTEC, so my spool up was compromised just a little bit. But if someone ran that turbo with a TMIC and got it Protuned with the AVCS wicked up, that turbo would be nasty for auto-x. Good low end grunt and awesome top end.
For the smaller courses that were really tight, I would have some "lag" issues. But you put my car on a larger course like Peru and WATCH OUT!!

I dont think anyone can get ahold of VF42s. Came on the S204s only, and they arent selling off their turbos ;)
Anti-lag sounds alright for the short amount of time that runs take... I wonder if theres a decent EM solution that has is for under $EleventyBillion$.

Tim,
Just FYI, the new UTEC SW has wastegate clamp functionality in addition to the ability to change rev limit. I'm looking forward to seeing the difference that it makes when we don't crack the wastegate at all until 14 psi or so. Of course it won't be a direct A-B comparison because I'll have a little more displacement and a little more compression with the new SP motor.

I think Rallispec or Gruppe-S can get them, I have seen them advertised before.
Rather expensive... I think it was like $2500.
The VF36's are readily avalible though, and they are an upgrade on the VF37.

Joel, I have the new firmware for the UTEC on my car right now. IT'S AWESOME!!! So much better than the old system that still used the MAF.
But I am using the DTEC to control boost and with that you can decide how long to keep the wastegate completely shut by modifying the spool threshold. So if you want to run 20psi and put 50% in for the spool threshold, it will keep the wastegate completely shut until the DTEC sees 10psi, then it will go off the map programed in the DTEC. I normally kept mine right around 60%. Anything higher and the boost would ramp up to quick and cause massive corner exit crazyness!
But what is this wastegate clamp functionality the UTEC has? Never even heard it brought up in the UTEC forum.

I vote for the GT32. I drove a car with a non twin-scroll GT32 set up and it had a huge powerband, lots of torque down low and great throttle response.

I also just read that you can "make" a VF42 using parts from like a VF22 and a VF37/36.

MRT lists the VF42 as having more blades on the compressor wheel than the VF22. (IIRC, the VF22 has 6 comp baldes, the 30, 34, 39, and the 37 all use a 7-blade wheel).
I have a VF37 on my STi, if you are looking for top-end don't get a VF37. I am at a high elevation, so my experiences might not precisely translate, but even with an adjustable AVO WG actuator, the boost still tapers off to 12#s by redline. Please note that this is at 5000+ ft. in elevation, the VF3X series turbos all drop off to 12PSI at redline up here. The throttle response of the VF37 compared to the single scroll VF3X series turbos is much better.

Correct me if I am wrong, but isn't the only difference between a PE1825 and the VF37 is that the PE1825 has a bigger hotside? This might get you a little more top end if you feel you need it. Of course most would argue that the throttle response is what you really want for pure autox.
Having not used either I am only talking in theory here...

I think we're talking about the same thing. I think they were calling it wastegate clamp during development, because that is what the guys at Knowledge said was on the way. I was looking at the new functionality when I was last up at the shop, and there was another name for it. In any event, it's going to be hot.

Ill do some more ressearch on this, I dont do alot of turbo ressearch.
You dont really want a "top end" turbo for autox, you want a turbo that has better mid-range since thats where you spend most of your time during an autox, and to have a turbo that kicks in soon in case the course does have some spots where its difficult to keep the car at higher rpms or inbetween gears.
But, I havent tried it myself so I dont know for sure either :p

Whether or not that is accurate, I dont know.

It's a GT30R. Chris was up at the MiDiv Solo Championships in August and the pictures on the internet don�t do the car justice, it�s amazing. It will be a quick sum b once he finally gets it's sorted out and gets back in to the swing of things. :cool:

Aparently, there is a "hybrid" VF37 capable of 400whp...
| RainMaker | 09-15-2006 12:32 PM |
Well, Im torn between a VF37 and a TD06-18g.
I have (currently) an EWG and a AVCR. These would be helpful on the TD06-18g, and I could buy it unclipped.
As far as the VF37... I've been told it works well enough here at sea level to hold boost a bit better than the stock VF39. With my FMIC and some of Clark Turner's AVCS mapping, I should be able to keep it making decent boost up top. For tuning purposes, I plan on putting a seperate intake air temp guage in front of the throttle. It will add nicely to the Knock Lite and the WBAF guage.
Im currently getting ready to pay for the Ohlins sportline coilovers, so I have a few months before I need to buy a turbo. The Green is alot of fun on the street :)

From what I have learned, the VF37 and the PE1825F use the P25 turbine housing. It is the housing used on the VF37 and the VF36. The PE1825f is a roller bearing turbo, the VF37 is a thrust bearing turbo. The VF36 is also a roller bearing turbo. The PE1825f uses the same compressor wheel as the PE1820 (IIRC, a 42#/min IHI wheel found in GM Deisel turbochargers). I am considering adding that wheel to my VF37. I've heard the same information from a couple of different NASIOC vendors, so I have some confidence in the accuracy of the above.
If a person wants good throttle response, then the VF37 is a good choice. The downside is that it is somewhat expensive, as you have to get the header, up-pipe, and a downpipe that fits the TS turbo (or make one) in addition to the turbo itself.

having used a GT32... I don't see it getting much better than that. More or less impossible to get out of the powerband unless you shift to 4th instead of 2nd on your "downshift". Plenty of ablity to tune it as responsive or as smooth as you want it... Only real concern is how to tell yourself that you can't got WOT out of 2nd gear corners at 3,500rpm unless you like wheelspin.
that said I haven't tried the larger twinscroll IHIs.

For the smaller courses that were really tight, I would have some "lag" issues. But you put my car on a larger course like Peru and WATCH OUT!![/QUOTE]
:lol:
I have an idea, why don't you drive my car in peru, oh, wait you already did;)
just wanted to say hi! haven't talked in bit...

whoh... not topping 300ft-lbs to the wheels till after 4K? Seems like the twinscroll IHI isn't getting going that quick, though could be other things in the setup slowing it down.

I think you'd need more than 1 turbo to be competitive enough. I wouldn't touch SM here since Bob Tunnell is a local. He beat my by 16 seconds (total) at the Denver National (I'm in a stx wrx though).
Now if I had a 3 liter swap, then I'd be interested.

Stories of this turbo continue to intrigue me...

Yeah.... Im investigating the GT32 as well. Trick is to find a) a real twin-scroll kit, and b) an affordable kit. Im under the impression that GPMoto is no longer doing much (if any) business...
Perhaps someone will have a kit for sale one day used. I'll go do some searches.

The superfast SM cars are destroying PAX right now, looking through the results from the Denver NT, he paxed nearly a full second faster than the entire field. (yes, that's after the index is applied.) I expect the indexes will be adjusted after nationals this year.

Yep. SM pax is soft for a real SM car. It's basically the same index as BSP, but you can do a ton more to the car. I would expect a car like Bob's or Vic's to destroy on PAX this year.

Great the SM PAX is going to change
