Enough fuel for 20psi?
I am getting maximum 92.5%IDC at 12.6 A/F ratio running 20psi from 3300rpm dropping to 16psi at 7000rpm. I am running 520cc (at 3bar) STi injectors with a 355bhp fuel pump.
Will an increase in the fuel pressure from 3 to 4 bar using an uprated regulator reduce maximum IDC to 85%?

That's leaner than most people shoot for. Is that on C16 or something?
I can't comment on how much your IDCs will drop with increased f/p. |

((3/4)^0.5)*92.5%=80.1%

OK on second thoughts my maths is'nt so bad or is it my memory I recall Mr. G Bell mentioning that equation, must have forgotten. Thanks for the reminder |
