At what RPM does your car reach maximum boost?? Need to check something
Doc

 

Quite a tricky question doc, it depends on car type, ecu type, if the car has any modifications etc.
Post some more info about the car etc, hopefully someone will have a similar spec to that and be able to give you the info you require

Early impreza with td05 probably about 3500 (11psi)

Later impreza with td05 probably about 3800 (higher boost to acheive, 13.5psi)

Early impreza WRX wagon with td04, probably about 2800 (11psi)

Latest impreza with td04 turbo (97-> really) about 2500 (13psi)

Anything around 3200 and above is going to have a sizeable turbo.

Pavlo has answered my question really - my boost peaks far to late, i have no mid range high turbo boost
Thanks
Doc

 

So what problems you having then doc?
is the car peaking boost then dropping straigh off??

Tony

 

Tony,
I can only get 12psi boost high up the rev range in fourth the problem i`m sure stems from the boost solenoid which has been changed from the standard one, I just need to find out which way to plumb the old one back in
