11psi and as the RPM go up the boost dies due to 2" exhaust lol
We hit 129kw at 12psi one run but backed the boost off for safety.
As for the whole pod filter thing Weq was going on about..
Good in theory but not true..
I lost power using the GReddy filter.. so the heat shelfed ones saying
Nuff said
Need a new head gasket though

Too much timing. D-series engines can take on average 1/2 the timing as a b-series engine. You have to keep combustion pressures down, otherwise you will blow the gasket.
And the filter sucks. I never once said the (dirty) greddy filter was any better.
And the exhaust has little do with the greddy turbo loosing boost. Its all to do with the bleed valves. You need a proper electronic boost controller with closed loop feedback. The stock actuator is really really bad. You need to shorten the arm until its reaches about 9psi off the gate, then get an electronic controller to up the boost from there. I had best success with the GReddy profec B (now called type-S) and the turbosmart eboost's. I tried other electronic controllers, but none could hold the boost over 5500rpm. This was with a 2.5" exhaust. Bleed valves had NOOOO luck at all.
This is a typical australian thread. not learning anything from other peoples previous experiences, and then re-inventing the wheel over and over.
