Question Twinscroll help/hurt/not matter?

Anyway with all this talk of transmission snapping RWHP, I was just thinking about all the parts I just ordered and I think I may have done myself in

I am going with the PFAB Twinscroll & Gt35r with the help of Methanol and a 3mm H/G. I dunno if this will get me around the 500-550RWHP (350ish Torque?), but with the Twinscroll spooling quicker and making more power lower, I assume this will put more stress on the Transmission, or would it be a more gradual increase in power so maybe a little less stress, or am I just a jackass and it wont make a difference at all?

I will probably keep the Boost down in gears 1-2 and go all out in gears 3 and higher, but then whats the point of the twinscroll?

thoughts/ideas?

Also will my 255/40 tires stand much of a chance at 65MPH???? I'll be honest guys the thought of my back end coming loose at that MPH scares me, which I guess is a good thing.......

With a tune by Evans, I would imagine that you'll easily surpass 550 with meth and 3mm on the 35r..

Also - first and second are going to be completely useless. Third is the new first gear haha

TQ kills trannys. if you make boost sooner, tytpically you make more tq. hp is a function of tq and rpm, so if you make HP sooner, your making way more tq sooner.

the rule of thumb i have seen is the tranny gets pownd in gear when you make 600+whp, which is ussualy 450-500+tq.

its a game of pay to play. and the weakest link will always break first. your gonna make serious power on a stock motor. pump you will be 425-500. water/meth your gonna be 550ish. if you wanna push it, 600. shit WILL begin to break. just accept it and dont worry about it.

YOUR tires will bitch out. again, boost by gear will be your friend. but the better your tires are, the more power you can put to the ground sooner.

deadzero on his shit tires was spinning in 6th. i mean thats retarded. your gonna need some nice tires. either drag radials or r comps to get the most outa your setup. why make serious power if you cant put it to the ground.

oh boy, maybe I will aim for high 500's with using the METH, in case I encounter any Z06's and just stick with low boost (400 or so RWHP), although I am afraid I will be wanting to experience the high 500 RWHP all the time..............

either way, I either break shit or have a super efficient set-up and only need a little bit of boost to put down good numbers, either way I cant wait

with everything he says


also joey... the way you drive...you might blow your motor with that turbo. theres a high chance that your might have boost creep.

Even if the tune is perfect...its still a stock motor and one little mistake can blow the whole set-up. I only ran this size turbo because i was rebuilding the motor and to run this kind of power daily because of the stronger motor.


Also... i did a burnout in 6th gear past 110 mph. i keep thinkin it was 132mph but i dont wanna think about it anymore, That was scary!!!! i probably won't drive the car again with race fuel because of that experience LOL. there is a thing called Too much power.

your also gonna make much more torque then myself because of the twin-scroll. Like what Camuman said..the sooner the boost is made the more torque you will make.

Your gonna blow your diff very soon...a few rear mounts...if you don't launch the car im gonna assume your tranny will survive for a little longer. I know that im gonna have to change mine out i just don't know when.

yea.... you know what...maybe you should save an extra 5k on top of the set-up. just to have encase something breaks somewhere. or something melts...or you need extra safety equipment.. .yada yada yada... im not kidding either LOL

my whole summer has been strengthen strengthen...melted stuff...heat shield here and there.... but its sooo worth it after its perfect

Yeah, I never launch the car and according to Pang, he said there is pretty much 0 chance of Boost creep with the Dual 38mm MVS Tail Wastegates, but like you said, when I get everything squared away it will be a niiiiiice set-up. As far as melting shit I will have the battery & Fusebox re-located outside the bay and the manifold and downpipes/dumptubes will be not only coated by Swaintech, but also wrapped with exhaust wrap. I also ordered this system yesterday, you can never be too safe

I would say on that dyno you should be well over 500 closer to 600 capable but it's all relative. You can dial back the psi to control your HP. I guess the question to ask yourself are you overbuilding your set up for your goals. The stuff your are getting is all top quality but the diff will go with that much power and the tranny is a ??? You may want to consider a rear option in the near future. I think your car which seems to be a little HP freak should make some crazy number with your set up. Maybe some of the best around for that type of set up, with spool and top end.

yeah, as far as the diff, have these things been known to snap mid pull? I have launched my car once in its 5 years (95,000miles) of ownership and it was when I first got it.

Problem us with me, whether its food or sex I have NO SELF CONTROL, so with the METHANOL I would like to see what this set-up can do, not for daily, but just 'cause

One thing is for sure, if I find myself racing as many people as I did when I was Greddy, my motor, my car, and my license wont be long for this world
