[SleeperGT]

Here's a little input on the Kenne Belle, not sure if is worth anything. This past weekend I had my car tuned and there an 02 GT getting his Kenne Belle, 10 pound, intercooled kit tuned also. He made 355 rwhp. He had all the standard mods, exhaust, 90 mm MAS, plus long tube headers, stock gears though with a 5-spd. My Vortech'ed GT, running 6 pounds of boost made 320 rwhp. My boost was down because I did not upgrade to the smaller pulley when I had an air to air intercooler installed. My tune was done on the stock, largest SC pulley, 3.6"". When the car was tuned without the intercooler I was making 350 rwhp on 12 pounds of boost. That's on a total investment of about $3600, including installation. That is on a stock MAS, 30 pound injectors, no C&L upper intake, and stock throttle body. It did have a custom tuned Diablo Chip. These dyno #'s are on a Mustang Dyno. I went for a ride in the Kenne Belle GT and it was impressive, especially considering he was on the 3.27 gears. Amazing how different the boost works with the roots type blower, I mean he was at 10 pounds of boost instantly, no gradual build like the centrifugal SC. He hit the gas and that boost needle instantly stood at attention.
