BE WARE OF SPELING ERRORS>>>
I dont know the Fuel Pressure because the gauge dose not come in until next week


Well last night i installed my friends fuel delivery... Fuel Rail, AeroMotive FPR, new lines and a set of 550cc's when i was street tuning(only enough so that he could drive it to the dyno) his car under full throttle into some boost .. the car out of no ware would just lean out ....or would feel like a big misfire... what i think is going on is the fuel rail is emptying out at higher load and the fuel pump is not copping up with the FPR seting and in result lost of Fuel pressure...

Just wanted to see what you guys think is going on...?
AFR 10.1-10.5 Wideband...Techedge...

He has a walbro 255 its just that he has to go pick it up form my friends house didnt have it with me last night...

 

i dunno what the problem is but if your getting 321whp at 20psi on b18c1 sc61 there is a leak somewhere.

 

THis is on a different car not my car...

 

 

def the fuel pump,
but im wondering on your setup, did you find out what cause those low numbers?

 

His clutch could have been the probelm. It can not hold the amount of power it has so it slips after a certain RPM. Also his catch was setup incorrectly. I honestly think he should be well into the 400+ hp mark on a dynojet or dynopack when we get everything right.
