Re: Full port AI + 8lb Procharger

Im running mototron 60lbs high imppedance injectors and my stock FP regulator gives 50psi ??? (no vac) so i have set the injectorconstant to 65lbs.
At 570rwhp 5900rpm they are at 70% dutycycle....
stock fuellines, Walboro intankpump widh new wiring from the alternator, V-plus volt booster.
Tried lucas 42lbs before i installed the new wiring to the pump, FP at 58psi injectorconstant 49lbs and they hit 100% dutycycle and the fuelpressure dropped at the top....

Im very pleased widh the mototron injectors, idles perfect at 950rpm...

I honestly have never used the Sieman 57lb injectors but I will say overall that Sieman makes a great injector. I have used Siemans 55lb (low impedance injectors) and am currently using 83lb Sieman injectors. I would email Jack at Racetronix and see if he has any experience with the Sieman 57lb injectors.
