Fuel pressure Questions on 8psi
I'm running 8psi on a turbo setup and I'm running into fuel problems.
I hooked up a fuel pressure guage so I can monitor as I drive around. My stock idle low rpm driving is around 45 psi give or take. When I mash the gas in WOT sometimes it climbs to 50 sometimes 60 then falls to 30 sometimes to 20 Up in 4500 and higher rpm. It's different in pressure every time. Needless to say it's running lean My setup is walbro 190hp Supra 3.0 312cc injectors. Running 8psi on t25 My questions 1.What fuel pressure scenarious SHOULD I be seeing after going WOT 2. What could be causing erratic fuel pressure. Stock fpr? Thanks for any help! |
I'm almost afraid to ask: what engine management are you running?

What's an engine management system?

From 5 month's ago: rich then lean

Are you using a fuel pressure regulator? If not, don't get one but get a stand alone ECU.
