When are you GT35 guys hitting full boost and what psi?

 

+1, also go back to the stock int mani just to check it out....

your exhaust manifold may have some play in your spool as well

 

What hotside is on the turbo? Drop down to a smaller hotside and you will decrease spool time.

 

DAM i forgot this one...good idea

There are situations of leaking intake manifold gaskets, the car will build a lot of boost but still build no power...

 

i have the hated ATP 3037s/3076r kit and i love it. hit full boost in 3rd at about 4500. full boost being 21.5 psi right now on 93 pump.

 

Sheesh, your car feels like it has 10psi off idle! Amazing. But of course, there is just a leeetle bit of difference between your setup and what other 3076R users have . . .

 

I hit 15 psi in 5th gear between 3700 and 3800 rpm with my 35.

 

Not toooo much difference, twin scroll housing/divided manifold but I don't think its that outlandish to expect out of another well designed setup or possibly a stroker like mine.

Not too much difference? A worthwhile note from first-hand experience . . .

IF you ever get the opportunity to drive such a setup, you will know the difference before you even get the turbo into boost. Believe it.

 

Fair enough, never driven one I am sure its mouch more responsive and quicker spooling just a shame that doesnt come across on the dyno.

What do you mean 3037s/3076r? I thought they were 2 completely different turbos...

Also, it appears i hit full boost around 4200-4300 in 3rd .

 

im missing something. what is driftos set up? a twin scroll 3076r?

 

um to be honest, im not 100% sure of the differences. we both have the ATP 3037s HKS version, but im not sure whats differs it from the 3076r

 

Yes, using the ATP twin scroll turbine housing.

 

huh??? so he has a 3076r with an ATP twin scroll housing? wow i want to see this
