as the topic say I need opinion on this subject... So im boosting 15 psi and I know if I could a little bit more on it... when I was tuning it I reached 20 psi a cupple of times... I loves my turbo for the fast spoolin... but at higher rpm im not sure of it

My car pull really hard but when I go over 6800 the engine begin to feel less powerful ... but I think that my OEM spring, valves, cam could cause this...

I want to add crower spring and ret. + cam + bigger valves ...

So give your opinion...

 

anyone ???

 

that turbo is worthless after 14 psi. and does not have the power to flow over 6500 rpm.

if your pushing more then 15 psi. your prolly just blowing hot air. if you want more power you need to upgrade the turbo.
