makes you wonder how accurate your track is i dyno'd at 535whp on a big single and i dont trap 130 at my track. Not to mention how does gt35r's max out on 21psi ish of boost and your tiny stock twins are not? Im not knocking the car or you but either your track is way out of wack or maybe mine is.

 

Just cause you make big hp numbers doesn't mean you are gonna easily be able to go a certain mph at the end of the track, there is so many things to consider. The big single has more boost lag and more time in between shifts where you are not accelerating as fast. I believe every little part of your run whether it be good or bad will show in your et and your Mph. For example, If you have a slower start then your mph at the end is not going to be as fast as if you had a great fast start. also weather conditions play a part and everything else.

I also ran low 11's with bad starts and 126 mph last year at MIR in Maryland that has a low altitude. My local track is actually known to give slower times because of altitude and my peak boost always seemed to be a little lower there.

My first trip to the track with my big single turbo at 18 psi I only did a best of 11.6 @ 116 and it felt slow. But I think I was injecting too much water at that time.

My stock twins, depending on the weather and boost controller settings, would spike to 20-22 and then fall off to 17-18 psi.

 

Then, honestly, you either don´t produce as much power as dyno tells you, or powerband is very peaky/laggy and lacks average power.
You can´t quote some boost number and claim that turbo is maxxed out. For example one could run even more "boost" in midrange and fall of in top end.
Also IIRC combined turbine flow of twins could be slightly better than turbine flow of GT35R hotside as this is place where GT35R lacks....

 

hey a question, are you using the Tilton clutch flow control valve with a single plate clutch? and how do you install it exactly.

just started doing research on the little valve.

 

Yes. Search my posts about it, I posted pics of my install and all the part numbers for the fittings I used to instill it in another thread about the valve.

 

amazing what you got out of the stock turbos

 

Just saw this comment. A guy with a dyno sheet questioning the validity of a guy with a time slip Love the internet sometimes.

 

haha. and I'm pretty sure gt35r's do not max out at 21psi

 

haha yes. my biggest enemies on the road lol. my friend on everything stock 1st gen gsx, fully gutted except racing seat n what not, tuned for e85 on 14psi went low 12s all nite. just imagine a built motor w/ 20psi w/ that weight... i want a 3 rotor 600hp lol

it is just as accurate as any other track ive been to. ran 15.2@92-93 at PRP, MIR, and NTR (pa, md, oh) in a bone stock 2.2 cobalt back in 05. Had civics at those 3 tracks also with consistent times/mph to each other

ive seen higher psi out of them, not on an rx tho but a piston motor. i seen another pitt guy posted about meetin up or something, id be down to join ya guys lol

 

that is crazy fast for stock turbos! i'm at pittsburgh raceway all the time i'll be looking for ya!

 

Excuse me for being a noob lol but what do you have to do to keep from breaking the rear end making that much power and getting good 60's? And what do you have for shocks? Coilovers or not? Very nice times!

 

the stock fd rear lsd will break so you can put in a TII FC rear LSD and they hold up well. slip the clutch a little, don't just drop the clutch which will result in breakage. You can keep the stock suspension. I have stock springs in the back and koni yellow struts front and rear, front lowering springs, but you can just run the stock suspension which is a good setup. The crane 2 step and clutch line flow control valve helped me be more consistent and better results/times. thanks.

 

wow nice set up

 

my news challenge

 

nice numbers on the stock twins

 

nice! That's one clean, quick car.

 

Thanks guys

 

impressive! nice time!!

 

Thats really impressive, 411hp and right around 2700lbs with you in it... Power to weight is awesome.

 

Great Pass!! What size injectors are you running on the motor? Also ; youre running the stock turbos non sequential correct?

 

Thanks. That was with the 550s and 1680s, and non sequential stock turbos.

 

nice time

 

sweet!!!

 

She's making power with the trap mph. Sweet!

 

Thanks.

I took all my blown stock twin turbos to the scrap yard, along with a door, a trunk lid, and a ton of other old mx6 parts and stuff (a truck load), and only got $50 bucks for it all.
