I have sent my Throttle bodies to CFM Tech to have them tweeked to 720cfm each. Now that they are no longer restrictor plates...how much horsepower are the injectors good for?

Engine specs: 575sci/502 stock bore/stroke, 7.5:1 CR, whipple low pro chiller, 871 stripped littlefield with triangulated discharge. Stock iron heads with Velako exhaust porting. Cam to be determined by Marine Kinetics

More info: On stock motor I was at ~9.5psi boost slightly overdriven

Depends if you turn pressure up, 650-700 assuming .60 or so bsfc, Smitty

I've been at 704HP(.030, 3.5" pulley, IC, roller cams) for 150+ hours with stock fuel pressure, TB's, blowers and computers. I've held it at 5300RPM for 10+minutes several times. I've contemplated the TB and blower changes. Let me know how it works out.

I also have an adjustable FP regulator set at about ~32 psi and 120* stat.

what horsepower are you currently supporting with them?

Teague claims 700 with a chiller, pulley and fuel pressure increase...everything else stock...I would think I should be almost there the way it is.

I do have a map from somebody with a similar setup with the limiter a 5800...and I'm on it with a 32p 5 blade

AT 750 with mine. punched out to 509s Alum heads smaller pulley. Started to lean out and Smith junked all the stock fuel delivery and runs great now with same injectors.
