LS3 fuel pump and injector limit Anyone know what the fuel pump and injector limit would be on an '09 LS3 vette?
If I could hit a measly 640rwhp I'd be happy.

Rule of thumb for the fuel pump is about 450-500.. Best way to tell is to put a fuel pressure gauge on it. If it is a wet system the injector is not an issue. If its dry you need to watch the injector duty cycle as you go up in the power level. What size are the LS3 fuel injectors?

Using your wet plate kit for the LS3. I spoke with Chris and he recommened the Racetronix wiring harness which sounds like an easy fix. Most people agree the ls3 pump limit is around 580rwhp.

cool. No nee dto worry about injectors then. Start small on the power range and watch the fuel pressure gauge as you move up. Dont trust your motor with other people experience. I have personally tuned identacle cars where one was fine at X horse power and the other one was having fueling issues.
Better safe than sorry.
