Default RE: Fuel Injectors

Injectors by themselves do not add anything.They are upgrades when using nitrous or a supercharger.Bigger injectors by themselves can really screw up your engine tune.(make excessivley rich)The nitrous or supercharger and turbo manufacturers will tellyou what size to use with thier applications.

Default RE: Fuel Injectors

You don't need bigger injectors right now. Like stated above they do not add hp in themselves, they simply help to support higher hp levels. At a 90% duty cycle (the most you would want to safely go), with the stock fuel pressure, 19# injectors will support 304 hp @ 6k rpm. After that hp level & rpm you will start to run lean unless you either bump the pressure or upgrade injectors sizes. You will have to have practically every bolt-on in order to NEED 24#'ers
