Our Camaro did about 297 at 5,000 miles (stock). Back to back with it was a '98 LS1 vette (also stock) that did 310, so I always thought the stock Vette exhaust was the reason when there was probably a bit more power.

Now, with basically a full-house 408, it does 515/530 HP/T at the rear wheels NA and around 250 more with nitrous.
The 'vette (sold it last Saturday) did357 stock (LS6, 3500 mi), 465/480 with the stock LS6 and a non-intercooler Magnusen on it,and 704/664 HP/T at the rear wheels with the 427 and procharger and full mufflers and pump gas: a bit more without but that's cheating.

Not really too interested in rules or requirements for posting dyno results, or whether anyone believes me for that matter, but . . .

Not that anybody would care, but the Porsche does 266/244 HP/T at the rear wheels. Remarkable it can do 13.5s with only that much and an auto trans.
