1400cc/30 sec injector flow rate?

not sure if CIS flow rate can cross to EFI, not sure why not but I did a check for a 400HP motor,
it called for 455cc/min which is 227cc/30 sec.
227 x 6 is about 1365cc/30sec.
this is at 100%duty cycle. the flow rate goes to 1700 for an 80%DC.

the early FP was 1170cc and the later FP is 1500cc.

I was told by larry that the FD factory setting is about 20%below max, if so that is about 185cc/30 or 373cc/min. (based on 1400cc)
at 80% in the calculator a 370cc injector flow rate supports a 260HP engine.

at 100%DC a 370cc/min flow rate supports a 325 HP engine which would support a stock engine.

so based on 100%DC and 1400cc/30 that comes out to 466cc/MIN (at the injector)which based on the calculator should support 410HP.

there was a BSFC figure in the calculator, I entered the suggested value that gave the highest flow needed (.65)


can you post you CP under boost? 2.9?
you may want to drop this pressure
