You're only making 326rwhp running 11psi? You're running stock E7 heads? Thats holding you back big time!
I'm putting down 400rwhp at 10psi with 302 stock bottom end componants (other than balancing), mildly ported GT40 irons and Explorer intake. 1.7 rockers with stock cam.
I would seriously think about getting some better heads if I were you. Those E7's are gonna bottle neck a turbo too.
Get some nice aluminum heads and lose weight too.
This is a good point. Power adder alone does not a stop-light beast, make.
It makes a little more sense where some of the turbo idea might be coming from since you're already aware of the associated headaches. Granted that doing many things is a PITA with a KB sitting on-top too.
