Ive got a 94 EX w/ i/h/e the basic bolt on and a wet 75 shot of nitrous. For a short while I did the FPR mod where you unhook the stock FPR from the vaccuum line and plug the vaccum from the intake mani. to raise the fuel pressure a few psi. Now I have an aftermarket FPR installed, what do i do w/ the vaccum hose? hook it back up right?

The instruction says to adjust fuel psi the motor must be on and the vacuum hose DISconnected, so when you disconnect the vacuum is that the fuel psi that you would have when its at WOT? so what should i have the fuel pressure set at for my n2o setup? As of now i have the psi set at 41psi w/ vaccuum hose on.

Thanks.

I run the FPR with the vac line on.

I'd add more fuel than that. I ran 40psi with just bolt ons NA. No N2O.

I'd do more like 50.

 

what is stock fuel psi for f22b? 38psi?

 

The service manual recommends 38-46 PSI with no vacuum

30-37 PSI with vac.
