Well I have read some part truths. It's kind of hard to compare a LS6 stock motor to a 03 Cobra forged motor. The reason the LS6 is running only 8lbs is because of 10.5:1 compression and not because the LS6 does not take well to boost. The 03 Cobra was built for boost and the LS6 was not. The 03 Cobra has 8.5:1 compression. Now if we make apples to apples. Add a forged 348ci bottom end to the LS6, drop the compression down to say 9.1:1 and boost the LS6 to 19lbs and see those #'s go from 550rwhp to something over 800rwhp. Also, I would like to address the price of the LS6 blower setup. It's more in the range of 5 to 6k. Not 10 to 12k. If someone paid that much they got ripped. The reason the race was so close was because of the difference in weight between the two cars. Z06 even with a passenger is lighter than a 03 Cobra with no one in it. If I had to do it all over again. I would purchase a 99 FRC and boost the hell out of it.. You get a V8, light car, and good looks. On our local board there is a 408ci C5 with twin turbos only boostin 13lbs and it makes 1100rwhp. Imagine that car locally...
