efi performance fuel injectors

NOTE: FAST Performance Fuel Injector rating assumes 45psi fuel pressure, your actual fuel flow at the fuel injector will increase or decrease if fuel pressure is higher or lower than 45psi--

HP rating is flywheel HP, not wheel HP--

FAST ECU can use either high or low impedance--



formula to find how much HP a fuel injector will support:

HP= (injector size) ×  (# of cylinders) ×  (.8)--this applies to 80% injector duty cycle (see note below)
divide above result by your BSFC(.443 for N/A) (.533 if supercharged) (.555 if turbo)

Note: suggested duty cycle is 80% (.8) to 92%(.92)--if you go over 95%, damage to the injector may occur from overheating.

Caution: Do not use low impedance injectors in factory ECU
Minitimer fuel flow rating is based on 45lbs of fuel pressure
