I want to put a supercharger in a mach 1 mustang. I heard that there is a good vortech kit that works very well for this car. I was just wondering how much HP i would get if i kept the whole thing stock except for the supercharger. It is a 4 speed auto also.

 

need more info what vortech kit? s tirm? t trim? but for the most part if you S/C a mach your looking at around 430 or so on 8psi maybe a lil less any more than 450 and your getting really really close to the limit of the internals
