Thanks

With the right fuel system setup 500rwhp

mrtstang

Around 450 rwhp with a poweradder, and around 500 n/a.

Ah 500 N/A

lizzyfan

Wrong and wrong!
500 rwhp with power adder and close to 600 N/A

I have a supercharger..and 42 lb injectors..Procharger 10 PSI

255 in tank pump what do I need to get 600 ponies out back?

I have other engine mods as well..

Thanks

600rwhp??
Your gonna have to get at least 60lb injectors and upgrade your fuel system (lines, tank, pump)
What year?

If they can really deliver 42 lb/h then its 42lb/h * 8 / 0.5 = 672HP n/a at 100% duty cycle, 538HP at 80% dc.

Running f/i its 42lb/h * 8 / 0.6 = 560HP n/a at 100% duty cycle, 448HP at 80% dc.

These are of course rule-of-thumb numbers--YHPMV...

99 model GT..

Has a SHM 5.0 with Forged Cobra crank, forged pistons..9.5 compression, forged connecting rods. Stage 2 port and polish on a set of PI heads. Stage 2 billet blower cams. billet oil pump gears...stock plastic intake stock TB and plenum. 42lb Bosch injectors..stock fuel rails and line. 255lph in tank pump.
Procharger P1SC 10 psi of boost. and some damn ****ty MAF gonna change it ASAP.
Ford motorsport shorty headers Bassani catted X pipe..no other exhaust yet..

Here is what I was thinking..LMK if I am barking up the wrong tree.
DBX97 MAF from Anderson..60lb minimum injectors, billet fuel rails( what size ), pully the Procharger for 15-16lb of boost( what size pully ). I am thinking I will need a better intake system than the stock PI plastic....thinking of a Bullitt or Trick flow..and a twin 65mm TB..

Fuel system completely evades me though..

point me in the right direction here guys..

Thanks
