6psi...8 psi is pushing it

I was told by Steeda (the local KB dealer) that I could go a max of 8psi without a Snow Meth Injection kit, and 9 with a meth kit and a good tune. (including 42# injectors, a 90mm MAF and god tune)

i dont want to waste my money on a 5 psi supercharger cuz they only add like 70 horsepower....i want more than that....but i also want to be safe...i dont want to ruin my engine....should i go with an 8-10 psi vortech???

8-10psi all day long with a good tune. There are alot of guys running more than that safely.

I agree - I'll be swapping my pulley out to 9 psi this summer and following it up with a good tune.
