Use this worksheet:
http://www.rceng.com/technical.htm#WORKSHEET

Approximate data:
BSFC = about 0.62-0.64 stock
Max Duty Cycle = 0.60 with stock ECU, 0.80 with aftermarket ECU
Fuel Pressure = 34-40 psig stock, more with upgraded fuel system

psi doesn't mean anything... any pump will put out 100psi. it just won't flow much fuel. what you look at is fuel volume... not PSI. the fuel pressure regulator controls the pressure. and you can't change the stock pressure without changing it (big job)
