i had absolutely none....i am speaking from experience. I ran 10 11.5's at 122+mph with it. THat was at only 25psi , stock intake manifold, throttle body, maf, ecu (with pump gas flash).

no surge whatsoever. Thats the point of the anti-surgering inside the intake side of the turbo. It prevents surge as far as i know.

 

What upper ic pipe you running and clutch? Did you also upgrade your fuel system?

 

how long do you have to wait before the boost kicks in?

 

I seem to be getting full boost around 4200rpm, but hard to tell right now... as I have uncontrollable boost... I think one of my vac lines has a tear in it

 

Injen Intake kit with the injen upper i/c pipe. Stock clutch with ACT Heavy Duty on the way. 720cc injectors, and walbro pump. Got all my stuff from prostreetonline.com

 

As soon as I hit 3500, i floor it

 

What exhaust manifold did you use? What was your spool time like?

 

Why not the ATP 3071R? That has better response right. Was thinking of getting that over the 3037s like yours but in the .63 a/r.

 

How much does the turbo kit cost?

 

it looked like in your first picture you have buschur's upper intercooler piping. did you change it? if so, why? didnt it fit?

whos flash did you use?

 

That first pic looks exactly like te stock uip not buschurs.

 

I hit 23 psi by 4000 rpms. I had a sfp manifold (but bet money those $200 ones online are better than that was)...lol

just a question. But on the ATP kit or any 3037s turbo, looks like they have a 4" compressor inlet, does the kit come with a stepdown hose so you can run normal sized piping for us who have to use intake pipes with the stock MAF?

 

bump.
