How much fuel for 300 RWHP?
 
FOR TURBO ROTARIES...

I've done some figuring and thinking but want to know if my numbers match those who are more in the know with more experience.

How much TOTAL cc/min fuel injectors are needed to safely fuel a 300 RWHP car?

List what you think the total of all 4 injectors should be assuming 40psi fuel pressure.

Also what duty cycle, and BSFC you usually figure for.

Have you tried using a fuel calculator?

Both the FC and FD calculators are optimistic even though the values are FLYWHEEL.

Stock FD fuel injectors are good for a little over 300whp, maybe 325 or so safely. So 550X2 + 850X2 is 2800cc

Ive used the fuel calculators, those are easy enough. My question is more to hear from the tuners on this board with experience as to drivetrain losses in our cars. Guys that have maybe monitored pulsewidths etc...

The turbo II has more in common drivetrain wise with the 3rd gen than the other 2nd gens so i was hoping to hear from turbo FC and FD guys.
