Fuel pressure

[Clutch]

Hello i have a tuned up nova GTE with EFi and my fuel pressure is at 2,5bar. With my FSE valve i can put some more pressure on, normally what?s the pressure used to a best performance?

More pressure means less top end?


Thanks very much

erm well depends on what your exhaust gas is like...
IE you will need to have the FPR setup on a RR to make sure that your not overfuelling etc.

ok
I will give 0.5 bar just to test and then i will see.
My exhaust system is a 4 into 1 manifold and a strait 48mm down pipe with a direct backbox.
I?m going to change the down pipe to 55mm.
About the camshaft i have a 280? schrink cam.

the exhaust size has naff all to do with it lol.

i mean the exhaust gases (eg the CO and O2 levels) Have you got a lambda sensor? if so then the ecu will just fix the fuelling so you wont really see any gain from adding more fuel lol

No i don?t have a lambda sensor.
It?s an E16SE engine.
About the CO numbers i don?t know but i can find out in the machine.
