Real rough, 550whp+ (although there is no consensus on this topic, searching will get you better info than just asking).

ok, now that i know i won't have big enough fuel lines, has anyone heard about the new perrin kit. does this kit require a sump system. they are saying the system is good for 1000 hp, im just wondering how much pressure that is, and if im a WOT will i have to have a full tank to make sure i don't cavitate my pump?

At 750whp, most tuners would probably recommend an Aeromotive a1000 type setup as well. Do a search on 'aeromotive' and you will get a good idea.

THe injectors and the pump will allow 650 to 750whp. But the lines are going to hold you back alot. You can try it and monitor fuel pressure on a gauge. If it falls off the lines are choked. At that hp level you should have:

Stock fuel pump
Swirl pot tank in trunk
Big fuel pump like A1000 or Twin Bosch
-8 lines
Aeromotive or other big rising rate FPR.
