[QUOTE="Boost or Bust, post: 16796347, member: 199611"] So I had a bearing spin on the idler pulley that’s on the supercharger bracket, that equaled catastrophic supercharger mount failure. I ordered the new bracket etc to replace everything and waited the month for the parts….. and that’s how it started. So I ordered a smaller pulley and threw it back in the dyno. I jammed a 3.12 pulley on the vortech S trim on a stock 97 cobra with a treadestone intercooler, 47lbs injectors, 255lbs fuel pump, bassani x with cats and dynomax turbo mufflers. The result !! The tuner looked scared on the first pull, 474hp and 431tq at 5800rpm. The car makes 9psi, we pulled the limter down to 6k, took some timing out and cleaned up the fuelling. End result is 463hp and 413tq if I remember correctly. They will email me the chart in a couple days and I’ll post it. The car works very well and pulls like a freight train to 6K. I guess I will be buying forged internals after all this year. I was trying to avoid it. Either way 463hp seems like big number for 9psi does it not? [/QUOTE]
