i have a 2001 mustang gt an i wanna know is their anyway i can achieve 400 horsepower with just bolt ons?? and wat bolt ons would those b?
i am not lookin toward the supercharger route

 

thats not going to happen.....it could happen if u build ur motor a hell of a lot...but w/ just bolt ons...thats not possible....and besides..the amount of money and time for each part will cost more and more time consuming than that of a s/c....for our cars s/c's are the way to go....

 

N/a it would be almost impossible to reach 400 rwhp with a 4.6 even for a 4v! You could do it with a good nitrous kit (if you consider a bolt on) and full exhaust,t/b/,plenum,tune etc... .

 

Not impossible at all with a NA 4V. Shawn Johnson and Jeff Schmell are both close to those numbers with UNPORTED heads and STOCK cams. 4V would be pretty easy.
2V is damn near impossible. If you did, it would have way too much compression to be streetable. 330rwhp is about it for a streetable 2V combo.
