RE: New fuel pump?

i have the saleen 475hp upgrade (thats at the crank) and the fuel pump stays the same. i'm going to brenspeed and have their stage 3 kit done later this month and that would be 500 plus at the crank about 420-430 at the wheels. for that you have to get a k/bell boost-a-pump. i'm going to have the gt500 pump added instead, but hope this helps you.

The only reason you should need to upgrade is if you are F/I with some big numbers or your spraying a wet kit over 125 shot.
