The Best Injectors on the Market. Period.
Precision-Flow™ fuel injectors deliver the super-efficient fuel
delivery that high horsepower EFI engines demand. Engineered to yield
faster throttle response and superior fuel atomization, FAST™ injectors
are manufactured to the tightest tolerances in the industry and are flow
certified to ensure consistent performance.
High vs Low Impedance Injectors?
a general rule, you will need to run high-impedance injectors whenever
you retain your factory Engine Control Unit (ECU). Failure to use
high-impedance injectors with a factory EFI computer will cause severe
damage to it. FAST™ offers high-impedance injectors up to 60 lb/hr, so
we’ve got you covered for nearly any performance scenario where you
would still want to use your factory computer. For an aftermarket ECU,
like the FAST™ XFI™ system, low-impedance injectors, available up to 160
lb/hr, are the way to go.
About the Injector Chart
FAST™ injector chart will provide a general guideline as to the
injector flow volume needed based on expected engine output. NOTE: fuel
injectors in and of themselves do nothing to produce power, so don’t
choose a larger injector because of the peak HP rating of the injector
–too large of an injector will only waste fuel and hurt your throttle
response, much like overcarbureting a non-injected engine-. Select the
right injector to support the power that your engine produces -you’ll
never run out of fuel, and you’ll experience great throttle response, a
smooth power curve, and good fuel economy.
