What are your fuel pressure readings on your car? mine is at 70 psi then goes to 66 after driving for awhile.

I'm not the 700hp guy but that 70psi sounds kinda high. What fuel system are you using?

j37hasag37

255 walbro. i also have a tt on it.

From the manufacturer the oem fuel pressure regulator is around 45-50 psi.

Ur fuel pressure should increase directly related to the boost. So if ur base pressure is 50 then ur pressure at 10 lbs would be 60 psi. 70psi for fuel pressure is alot unless ur boostig like 20lbs

Damn man imagine 70 psi of boost, lol.

j37hasag37

where the hell u getting these numbers from?

man where is the g37 with 700 hp guy. we have the same set up.

if u have a turbo'd g37 and have a fuel gauge let me know. other than that stop giving me weird math that makes no damn sense.

How about I was just giving example numbers to try and help out. I'm currently finishing up a gt35r build on my friends 350 with a cj motorsports return fuel kit, twin walbro 255 pumps, 1000cc injectors and aeromotive pressure regulator. All I'm trying to say is that if your driving around with 70psi of fuel pressure that seems really high to me unless your boosting a high amount.

Don't expect to get help from the forum with an attitude like that, he was clearly trying to help you out, show some appreciation.
