So im about to max out my stock 24 lb injectors, and i was thinking about goin with some LS1 injectors for $60 NIB. Does anyone have any advice?

Im thinking i should be somewhere in the range of 450 NA rwhp.

 

Verify the pressure at which the injectors are flow rated. The LS1 fuel system runs at 58psi (4 bar), compared to only 43.5psi (3 bar) for the LT1. You need to verify that the injectors will flow 28#/HR (or whatever they are claimed to be.... LS1 injector sizes vary from year-to-year) at 43.5psi. Its always been a little fuzzy to me what pressure the stock LS1 injectors are flow rated at.
