Over 625 RWHP with stock motor and stock fuel system? Step inside...

[daltron]

Curious to know what setups people are running including pulley size for those making over 625 RWHP on the stock motor (or stock motor with OPG/crankshaft gear) and stock fuel system.

Changed it to 625 because in California I think stock fuel system will be hard pressed with our 91 octane.

I ran out of fuel with my procharger with a 3.50 pulley ...Had to add a BAP and 1000 injectors... 640/580 now but once again I'm out of fuel @ 7000 RPMs.. I would like to go to E85 but will have to add the Four fuel system ... Stock exhaust with cat deletes , stock oil pump and cam gear ..

640rw with Roush phase 2, BAP, FRTB, and original Roush injectors. No opg. I'm at the edge with these injectors and 93. I also add a little Torco. Almost forgot, removed lid from the air box which for some reason is worth more power than I imagined.

694/521, 93 octane, stock headers and cats, no BAP, 72# injectors, 3.625 pulley.

92 octane here, 700 rwhp, BAP w/1000cc injectors.

I think the centri cars have a different fuel demand than the PD blowers
