get alky! itll majorly boost performance on 91, coupled with its massive torque output and the 35r that will be a sick street car. And yea on a dynojet...id say 450-460...but yes that torque is low...
id also get bigger injectors, (heir [?] on the side of caution)
I/C piping (lose the flexible mesh and inprove turbo efficiency)

 

Thanks for the tips. The car is still a work in progress.

 

Well it depends on the track that you are at. On a technical track like ButtonWillow or Street of Willow this turbo might be a disadvantage since you lose mid-range power from the stock turbo. On a fast track like Big Willow, this turbo is beneficial.

I do not mind scarificing low end power for high end power, but you are giving up mid range power with this turbo. At 4800 rpm your are making 100 ft-lb LESS torque with this turbo than with a 16g. That is a HUGE loss in the mod range of the power band. At 5500 rpm the 35r makes around 250 ft-lbs and the 16g makes around 280-285 ft-lb, again a substantial loss in the mid range.

A turbo that would allow you to keep your mid range power and get a bit more top end would have been better for all the different road course here in CA.

On the drag strip, however, the 35r would be ideal.

 

I believe Andy is more of a street/drag guy then a open track guy.

 

I agree on streets of willow this setup would not be ideal.

However, I consider Buttonwillow a highspeed track, and I've actually ran that course with my 600 whp SPFWD Civic Hatch detuned to 400 whp, and didn't find it hard to remain in the powerband at all.

I think now that I have a platform/chassis that can handle that kind of power, buttonwillow will be a lot more fun and a lot less scary than my other car.

No doubt that the 16G is very balanced and matched to the EVO making it a very pleasant and easy to drive on the roadcourse, however, the quickest time attack EVO's aren't using a BPU type setup.

At first thought one would think the 35R isn't suited for road course duty, but there are many successful time attack EVO's that use the GT35R.

Not to say that my car is a Time Attack machine, as it is far from that, it is just the car I drive everyday to and from work for fun.

And I hope to bring it to the road course occasionally when time permits, so I can have fun with Earlyapex. Maybe he can teach me how to drive

 

Actually I think that GT35R would be fine on the track at buttonwillow and thunderhill. I am barely ever under 5,000rpm on both those tracks. The only thing I would be worried about is reving it to 8k in high G turns.

I look forward to seeing the car this week at thunderhill Andy.

 

Haha, no more drag racing for me. While I am definately not the best driver, I am a bit more familiar with the road course than you think. My previous place of employment was RCrewRacing, and the owner loves open track, in fact Rcrew has entered the 25 Hours of Thunderhill a couple times through out the years. Most of the Open Track events I've attended are with Speed Trials USA, and I've never bumped into you at those, so that's why you haven't seen me.

 

Yea, I'm definately not revving it to 8000 at Thunderhill. The lean spot in that area is something I'm going to avoid. Also, I've never driven at thunderhill, only ridden passenger, so I will definately be taking it easy. The joke with me and cal at the office is that we are going to run parade laps. lol

That and the fact that the owner of Rcrew rolled his integra there a few years back, and had to be medivac'd (sp) to the nearest hospital, and only the fact that he had a full welded and race prep'd chassis did he not lose his life. Yea... Definately, not trying to be superman in this car.

 

What are you boosting at?

 

i agree, most tracks thats a huge turbo...def great for drag though. It can be made into a track turbo with great tuning, alky (hint hint lol- low end torque), and a great suspension set-up. If your car can get through an apex with more lateral g's then you can retain more speed; hence the turbo will still be in its effective powerband. so yes, i think though too big, it is still feesible!

 

Will do! I gonna call anyhow after seeing your results you just posted. I am little curious what the gains were on the full-race manifold.

 

There should be a compromise between the 35r and the 16g. The 35r loses too much mid range for my taste and the 16g runs out of breath at the top end.

Isn't there a turbo that you can use that can combine both mid range power and top end power? It does not have to be either the 35r or the 16g. I am sure that there is a turbo set-up out there that can give you the mid range that the 16g has and 75% of the top end that the 35r has.

IMO, the car loses too much in the mid range to gain a lot of power up top. Isn't there a more balanced turbo for the road course?

 

the set-up im in the process of completing.... a 3076r with alky, 264s and aem.

ill be around 410-430 on a mustang.

 

True, I am definately not trying to convey the message that a 35R is an ideal track setup.

I think the 30R on race fuel or alky can give the characteristics you are looking for.

However, IMHO on the street the 30R (either 3071 or 3076) on pump fuel gives up too much low end power for not enough high end gain compared to a proper BPU 16G.

The 35R while gives up even more low end power than the 30R, it makes up for that fact with its greatly increased pump gas hp potential.

I've tuned 3071Rs, and 30Rs, and to tell you the truth around town the drivability with those turbo's aren't that much better than the 35R. below 4k they all feel terribly laggy. The difference is the 35R will suck you back into the seat and feel scary fast when it finally does kick in and it doesnt need exotic fuel or an aggressive tune to do so.

Also, I think that the dyno is a very poor example to judge exactly what a car feels like. It does not measure the engines transient response during partial throttle action, which is the real meat and potatoes of real world driving.

Going with a turbo like a 35R just means you have to adjust your driving habits, if you absolutely love the fact that you can keep your car in gear at 3k and just hit the gas and go, this type of setup will make you mad.

If you can accept that acceleration events require a downshift to get into the powerband, then the 35R will make you happy.

 

solenoid boost controller will help you get that boost faster. that powerband would look a little better. and a bigger throttle body will really help too

free up the flow so the turbo doesnt have to work thru un needed loads while building boost
