Low Boost Pressure

[N I B]

The R31s hit a nasty boost cut very early so don't go to far.

The R33s are easy to boost up using the factory controller.

Hey steve, what exactly needs changing using the factory solenoid to improve boost?

Rob77,

My 32 is boosting to 11.5psi (dropping back to about 10ish) now with the boost controller off. So essentially its running standard boost. Thats just from having a full exhaust system from the turbo to tip. Dump pipe made a HUGE diffrence to when the car comes on boost too.

I suppose i could set my boost controller up for 12, but hey, its only .5psi.

Besides, i think my HKS dinosaur boost controller has finally given up. It behaves very strangely.

steve-SST: at what boost level does the boost cut operate in the R31's, and how do i get around it??

cheers

with my blitz turned off my car only makes around 0.55 bar, with a cat back exhaust... should have the front+dump pipe on in the next few weeks.
