If i crush down the top of my stock regulator will it increase the pressure out put of it. I know kid's that used to do this to there 1st gen eclipse and talon waste gates, in theory there would not open until a higher then stock pressure was meet.

Will this increase my stock fuel pressure!

 

Yea, I guess that would work... A more efficient way to do this would be to buy an aftermarket FPR... I just wouldn't recommend that... Take a nitrous or oxygen (don't think you would wanna use CO2), "T" your FPR vacuum line, then pressurize that line... This puts closing pressure on the FPR's diapham intern bumping up your FP... That's how I run nitrous... I wouldn't do this on an N/A car just to get some FP tho, just get an aftermarket FPR... Just my $0.02... Peace
