Default Anyone have a good IFR for Motorons (60lbs) at 62PSI Returnless?

I searched and found lots of post on return cars, but almost nothing for returnless cars. Any input would be greatly appreciated!

Default

is that advertised flow rate at 43.5 lbs or 60 ?

43.5 = 2.48
60 = 2.12


the numbers above would be a multiplier to you IFR table based on advertised flow rate versus current FR

thing is your idle fuel press will probably be higher than driving, so you'll need to adjust for that

Those are the injectors I'm using, 60lbs at 43.5 and I believe it's closer to 70lbs at 62 psi.

so the multiplier will be 2.48, but check your fuel pressure at other than idle because it will probably be less, then you'll have to scale the IFR chart accordingly....the pressure comes out to 71.63 lbs
