umm im thinking you can run 13 lbs without having to change anything which the first thing that will need to go is the fuel pumps. but back to your engine, its not the weak link lol other things will need to go before it. ps. im a fan of whipples lol (hint)If I did add an aftermarket supercharger, what boost could i run without damaging the engine since it is stock?
if you still got the t56 in there 13 lbs is fine on it man. and for your irs get a irs brace and your good.im a kenne bell fan myself......but i would probably have to change the transmission and possibly the rear end before running 13 lbs.
what if i ran between 6-9 lbs of boost? would i still need to change anything then?
