well i wanna get either a twin turbo of a s/c. well what i wanna know is what kind of heads do i need and what kind of backup will i need to be able to push like 14 psi. i dont want the stock psi which is like 8.

new engine..... thats the easiest way. the 4.6 GT block is only good for 450 hp, and 14 psi should put you well over that. ull also need forged everything. other than that, get some real suspension upgrades including control arms and some wide sticky tires.

That about wraps it up. [&:]

forged evrything as in what. will i need to change my block or do i just need to change my heads and pistons?? or should i just change out my whole motor. i don'treally wanna change my whole motor. i wanna try to keep asmuch stuff in my stang as possible. i want to keep my motor 4.6 all the way.

Voodoo says he got 200hp out of 10lbs. So, its about 1lb=20rwhp considering its proportional.

for 14 psi right off the bat u may be looking at a new motor. the block itself is only good for 450 hp. i think 10 psi will get you that with a good tune. You might be able to go without a new block, but you will need a new crank, rods, and pistons for sure. the heads are fine. if ur going to build a motor, go get urself a 98 cobra block. they are aluminum and can withstand alot more abuse. then get a forged bottom end for it and some PI heads or use the ones off ur car. but im really not sure if the block will hold up for too long with 14 psi.

what kind of hp is voodoo putting out?? will my stock motor be able to handle 10 psi??

SpecterGT260

ive been told that 10 psi is the upper limits of the motor. you should do alright, but with stock internals you would be able to enjoy 8 for longer. same reason im getting a tune for a 100 shot and not 125. the guys at Delk Performance told me the motor couldnt handle it but id be better off in the long run with 100. other than the terminators, the modular motors arent really made to handle much.
