Oh, and Saabstory is the winner. I'm calling it Stage Plaid. LOL
I know on the rabbit stg 4 is larger still injectors, rods, pistons, return fuel line, 4 bar fuel pressure regulator and is around 400hp. Figuring with that intake manifold of yours, and headwork you get what you have... wait though, are you building the whole top end of the motor. The 2.5 guys running fully build heads that can rev 8500rpm out of their motors are running into the accessory belt shooting off at 7400+rpm
