ls1-Fast 90 and slp-kooks header results Ken for Eastside Performance retuned my 98 SS Camaro yesterday. The car has a 228/228 .576/.576 cam in it with patriot 98 style stage 2 heads. With the stock ls1 intake and slp headers, y-pipe and a borla, it made 382hp and 364tQ. This was a few years ago and I was very disappointed with the numbers, but what are you going to do.
Yesterday, redynoed the car. And a big thanks to Ken because the car had alot of misfiring issues on the dyno and Ken dove right in and fixed the problem. With a Fast 90/NW90 and a set of Kooks 1 3/4 headers with a true dual system that I built with a Burns Stainless x-pipe, borla xr-1 mufflers, the car made 431hp and 410tq. Needless to say, I'm grinning from ear to ear now. Thats a gain of 49hp and 46tq. The car pulls very hard now and doesn't nose over at all up to the limiter. The way the graph looks, it is damn near flat from 5800-6600, so it would probably still make good power up into the 7000 range, but I still have a stock bottom end with 98 rod bolts. I'd post the dyno sheet, but no idea how to do it.
