The Great C8 Roadshow
CitizensHaveRights:
Looks like it got deleted.
Somebody claimed a car magazine sent a C8 to him for dyno testing and it put out something like 560hp/545torque, at pretty much the same RPM, as if the power fell off a cliff shortly after 5400rpm. The numbers didn't seem to make sense to me.
gryphon:
GM is claiming that preliminary C8 dyno testing is 490 HP, so the other report is over 10% higher. Probably not 100% accurate for a stock C8.
CitizensHaveRights:
I thought advertised power was around 475-495 at the crankshaft depending on the exhaust options.
The deleted arfcom thread was talking 560 through the tires, or presumably 650+ at the crank.
Sometimes performance cars are understated, but I never heard of factory spec being that far off, not even the old L88.

gryphon:
Absolutely. Cars are understated for insurance purposes. That's why the HP rating measurement was changed years ago. Prop v. crank.

I don't see pics either.
