Stock Injectors
Re: Stock Injectors
They will be below 90% duty cycle up to about 375 flywheel HP. That's at stock fuel pressure (43.5psi). With a higher fuel pressure, they could support more.

Re: Stock Injectors
Do you already have the LT4 28# injectors? They will be below 90% DC up to about 420 flywheel HP. You need to tell us what your flywheel HP is to pick an injector. Can we assume your NX kit is a wet kit?

a lot more HP than I do.

LT1 (94-97) are 24#, the LT4's are 28#, as posted above. You could live with them at 400 flywheel HP. A set of 32#'s would give you room for future increases.
