How do you figure out what size injectors you should run? I haven't dynoed yet. Just was wondering if I should go to a little smaller injector...

I have a LT1. Here are my mods:
Forged 383- 8.75 compression
4-bolt main
Custom Blower cam
1.6 roller rockers
Ported pollished heads with matching intake 2.02intake-1.60 exhaust
D1SC 14lbs FMIC
75lbs injectors with injector driver
Headers and full exhaust without cat
A4

 

Those injectors are good for about 850 flywheelHP on a blower motor, without exceeding 80% duty cycle. I wouldn't make them any smaller.

 

As long as the motor will idle and you're not running out of fuel they should be fine.

 

OK thanks guys! It idles good and I have the Aeromotive A1000 set-up for fuel system.
