Hp roof for 510cc injectors

[1badgvr4]

I need about 275hp,and found some 510cc injectors,but i heard they might be to small.they have been cleaned and flowed to 528cc.Im tuning with only an old school 5 knob afc.Will they work with my setup.

510s should be godd for around 300hp

 

275 whp or chp? What octane pumpgas? Stock 37 psi base fuel pressure? You should have good 93 octane available in Georgia, right?

Yea 275hp to the wheels.Im tired of seeing guys with the same setup putting down like 240 around here.I will be on 93 octane gas,and will be getting your chip soon

 

Running it through RC's tech spreadsheet, it looks like you'd be cutting it pretty close with the factory 37 psi FPR. Assuming 15% drivetrain loss, that means ~325 chp. You would have to run those injectors at 100% duty cycle with a rather lean (for pumpgas) BSFC of .57. If I were you I would hedge your bet a little and pick up the FPR from an AT DSM Turbo, which is 43 psi, which would give you a true flow of 528cc, instead of the diminished 482cc at 36.3 psi.

 

^The AT fp regulator is a great idea Jeff!
