Fuel Injector Question

[Ed Wright]

Bobby, I found power by raising the fuel pressure with smaller injectors. For a race car, the 80% deal is internet lore. Many Stockers I know run their's over 90% all the time. They don't hang open. You need to change the injector flow rate in your tuning to reflect the new flow rate. Injectors are rated at 43.5 psi. For example, my 36lb FAST injectors flow 42lbs at 60 psi. That is the injector size entered in my tuning.
