RC Fuel Injection

Per this calculation, not knowing your numbers exactly.

Here is what I put in:
600HP
8 Injectors
.575 BSFC
.70 Duty Cycle
43.5 psig

It returns:
61.96Lb/hr
651cc/min

My choice would probably be 60's. If your fuel pressure regulator is not boost referenced I would probably upgrade that as well. This will allow you to set your fuel pressure at 45ish without boost and under boost it will increase 1:1 for every psi. RC
