Hi all,

Just fitted an FSE power boost valve to my 94 WRX jap import 260bhp version


what Bar pressure should I be running in the fuel lines??

tried 3 bar as I had been advised previously and it seemed to be down on power to begin with so I tried 4 bar pressure in the lines and it seemed better...just added another 1/4 turn to the adjuster as I still wasnt sure and it seems better still I presume it is now on 4.2-4.5 bar in the lines!!

any advice on this greatly appreciated as I dont want to run lean or blow all the pipes off and soak my engine with petrol...I'm travelling a fair distance tomorrow night and wanna make sure I dont end up with either holey pistons or a fireball by the side of the road!!!

Help me please!!

Sounds way too high, you will be loosing power up top as your running too rich. I would say between 2.8-3 bar is correct if the car is standard. Stick it on the rollers and get the fueling set-up correct.

I take it you did set it up with the vacuum to the FPR disconnected ?
