What size fuel injectors would I need for a dry EFI Pro Fogger kit like #04470NOS? The instructions say "a general rule of thumb is an extra 30 lbs per 100 HP shot".
I am using an HP ECU. I have a purpose nitrous built LS3 based engine, which originally used 42 lbs injectors, and I want to shoot at least 300 HP.

1) Would I need 120 lbs injectors?

2) If this was an E85 car, would I need to go to a 16 injector set up for a 300 shot?

3) What is the largest injector I can run on the street without running into "driveability" issues?

Thank you, Scot
