The rack is made by SURCO , with the light mounting kits and spare tire kit, got it from Summit. The alternator is Powermaster and it came with everything to mount it from Summit also, drivers side bolts up stock and pass side had and adapter to use stock bracket ,very easy install. You have to use 2 guage wire from alternator to battery. I also ran a 2 guage ground from the alternator case to battery. I know 12 psi is alot but as far as i know only thing internally is the 1.6 roller rockers. I was going to do a thumper cam last spring but decided against it, i did the rockers instead. when I first got it and stopped it from leaning out 6 psi seemed kinda dull when I started turning up the boost with some spare pullies then added the msd boost timing master. It really started coming alive. When i was at the dragstrip last racing a friend from work vette. I snapped the rear u joint and yoke stalling it up waiting for the green. First run was 15.5 just hitting the gas pedal, second run was a 15.3 i brake torqed it a little. 3 rd run when it snapped, i really wanted to beat him to the 60ft. So i stalled it up pretty high the boost started to build and boom never even moved. I have since installed a driveshaft loop and made in USA ,spicer u-joints and yoke. But i will never stall it that much again. It makes a ton of torque on the bottom first gear is crazy and the chirps to 2nd pretty good.
