It's all about the torque.

You keep telling yourself that. With exception of a few cars expect the numbers to be way off from the factory specs especially with the automatics. Get that car on a dyno, and I'd bet youd pull out a 130fwhp if that. My brother's grand prix gtp dynoed 220fwhp with pulley swap, cat back exhaust, intake, and aftermarket pcm (stock specs are 240hp) LS1's seem to dyno pretty close to their stock specs though, but still not what the factory says.

The only cars I can imagine pulling better numbers then what they claim are japanese cars complying with the gentlemans agreemant of 280ps (?).

The SRT4 and '03 Cobra pulled more than their factory rating.

The srt-4 pulls around 220whp a the 03' cobra from what I've seen 355whp. Still not over the stock numbers. Factor in driveterain loss, and yeah then a lot of cars including the camaro, dodge viper etc. are over their flywheel power. Some of the japanese cars have actually been known to dyno at 280whp+ however.
