So with h/c/i, p1sc-2, tb&plenum and exhaust you made 413rwhp at only 10psi!?!?
damnn!!
shits lookin good then haha.

thats kinda the same setup i want.

H/C/I, TB&Plenum and Full exhaust with either a vortech or a procharger
but i was gunna get forged pistons, rod and cobra crank just to be able to handle the power.
i should be very well off.

is your intercooled?
do you have a vid of the new setup?
you should make one if you dont

those are worked Npi heads though...take that in account when you think about your heads.

I was told that a full PI swap would raise the compression......resulting in the block blowing up when u put a supercharger on it

Ill go with some ported NPI heads instead :rockyou:

there wasn't that much of a difference between ported npi and ported pi on there site. The difference wouldn't make more than a few horsepower more if any.

so just porting the NPI heads and gettin a new cam and intake plus exhaust and S/C will make 400?
cuz i have PI intake, npi heads, npi cam and full exhaust. if i got another cam and ported my npi heads then S/Ced it, i would be set?
forged bottom end would let me run more psi as well.

its all about how much you want to spend and how fast you want to be ;)

Yep, that's about right. Another thing I just found out yesterday, is that the adapter plates that come with the Livernois kit are port matched to the head, but not so much to the intake itself. There's a local machine shop that's port matching the plates on my buddy's 96 GT, they're expecting good gains from this. I was thinkin about doing it, but I'm already pushing the limits of my shortblock so OK for now...
