Can anybody advise me on this.

I currently run a 92 WRX with a full scorpion exhaust (no cats) and air filter. Boost normally peaks at 13 then holds 12 psi, but after hard driving it drops and only manages to reach about 8 psi.

Drive softly for a bit and it comes back, can anybody tell me if this is normal or do i have a fault?

Also i notice a big difference in performance from day to day dependind on what mood the car is in (this is the best way to describe it)

Any help from anybody i would really appreciate.

 

Darren,

Not sure about your boost problem (?) but turbo cars are affected by the weather. I think the best conditions for power are the worst for driving fast, cold and wet. Hot and dry is bad.

Just realised your a newbie. Welcome to Scoobydom.

I have a very similar problem on my 94 WRX
But I have to drive 'SLOW' for a while before it comes back. And I really do notice the difference???????

This was even on a cold damp evening..

Same thing on day to day mooods aswell.....


Strange!!!!!!!

Didnt know there was even an Impreza in 92, I thought they came out the year after?

 

Scoootie....ever had this investigated then or do you just assume it is normal?

Trouble is mine always cuts boost when im showing my mates what an impreza goes like!!!

I also thought they came out in 93 but the data tags on the seat belts say 1992.
