I'd love to run in the SA class as I am a noob, but it sounds like tube manifolds are moving people to SA/U.
10's is plenty possible on a stock 9 turbo, if you have slicks...I don't see you getting that on street tires, but who knows.
Get it fully tuned spaz and then I guess we will all find out. I will match Andrews beer offer if you hit 10's on street tires though
