i think most of the guys dynos that i've seen are 210-220 to the wheels, and yes that's one hell of an underrating
Yeah the highest i saw was 236hp but Chevy has been know to do that stuff. You got a love when they do that stuff.selfinfliction said:i think most of the guys dynos that i've seen are 210-220 to the wheels, and yes that's one hell of an underrating

GM says 205hp @ 5600rpm. If you take a look at most dynos people have posted, you see about 175ish wheel horsepower (SAE correction = 1) at 5600rpm. Assuming around 15%driveline loss, you end up with 205hp at the crank at 5600rpm. And if you stopped the pull right there, you'd have 205 crank horsepower, just like GM says.
BUT.. most don't stop there. The thing is still building power up to 6500-6700 or whenever fuel cutoff occurs. By then you're making substantially more power.
So technically, GM wasn't incorrect, and they didn't underrate it. The car does make just about exactly [email protected] Why they chose not to publish a higher number is anyone's guess. Insurance reasons? CAFE? To give ppl a pleasant surprise? I would say 270 is pushing it, but GM certainly could have gotten away with calling this 230-240hp.
