i dunno what the specs of an SVT focus, but a bone stock 2G GST has like 205 hp at the crank and weighs in around 3000.

the BOV adds no performance on a stock car, and as for the turbo being loud my turbo whines very loudly when im on it, its stock but just have the silencer removed and all the little free mods and 16psi, i know of a eclipse you'd love to race, im sure he would give you a 3 bus headstart
