[QUOTE="sutyak, post: 15645071, member: 12833"] I have a turbo Mach 1 with (most of) a hellion kit. I swapped out the Precision for a Borg Warner and made a few other tweaks. It would also overboost due to poorly cut wastegate hole. The wastegate is 46mm, but the hole was only 30mm. After reaming it out it stopped overboosting. The bov was also terribly undersized and it would flutter, so I swapped that little 28.5mm for a 50mm JGS bov. 700whp is right where it should be. This car made 667whp around 18psi but the SPEC stage 1 clutch the guy had in it had to be slipping. It's also 8.5:1 compression with stock heads and cams, so basically the same as yours except with a Teksid block. When I bought the car the exhaust was dumped under the passenger side with a large glasspack. It didn't sound too obnoxious, but the hack job of the install and the fumes drove me nuts. I went with a regular Magnaflow cat back and it sounds decent. Not exactly the sound I wanted, but it's decent, and tough to "tune" the sound of a turbo exhaust, especially with the different X and Y pipes in the hellion kit. [/QUOTE]
