Fuel Pressure - LotusTalk

Those of you out there with adjustable fuel pressure regulators, what are you setting your base pressure to? Just wanted to hear back on some other setups and if anyone even knows what the stock base pressure is.

In case anyone else can use it it's 43.5psi with the vacuum line disconnected.

Stock pressure with the stock FP and internal FPR is 47+/- 1 psi at idle... FWIW... I've got pressures all mapped out in a thread floating around here some place... I've got it on my website as well so you can see what the FP does under load...

Also, make note that adjusting your FP to above what the stock FP is won't do too much good since the internal regulator is what it is... You can easily block off the stock regulator...

Not sure if that helps ya or not...

Best,

TP
