The early (1st) generations Vipers were pushing about 400bhp. They are not as fast as the newer ones...I believe they trapped in the 115-116mph zone. An 03/04 Cobra is not as fast as a zo6 (c5 or c6). The zo6 traps 117-118mph with a good driver. The FI Cobra's are hitting 111mph with good drivers. Also guys, remember there is more to the car than just straight line... To many comment on how the car is a "waste" or "overpriced" and then bring up quarter mile times. E.T. don't mean much, especially on a car that could see considerable road course action...and the suspension is setup for that, not low E.T.'s... Look at trap speed with a good driver...that shows potential.
