Got my car back again... But the problem is it wont boost pass 10 psi on the highway??? But on the road I can boost it to 13 psi. SO what the hell is going on? Am about to kick this car... Help please.
I gather its a BB DET by your other question and posts. Are you running a BoostControler? The problem I was having on the strip/high rpm driving is the t25 coulden't breath enough air for the motor. I'd set it to 13psi and it would hold from 3kto5k then it would rapidly drop from 13psi to 6-6psi from 5k to redline.
What kind of BC are you using? How long is a sec(RPM range?) I woulden't boost the t25 past 10psi for long periods anyway. You'll end up: Cracking the manifold,blowing out you manifold gaskets or destroying the turbo.
I found that the t25 DET turbo seems to make the most power @ 10psi. When I turned it up to 13-14 it got slower. I can pull 13.9's @ 10psi and the best I could get @ 13-14psi was a measly 14.2. I think the back pressure from the tiney t25 housing was making some mad reversion in my case.
