I love the Viper and a Stock viper vs. a stock 2003 Cobra will most likely beat it(unless the guy driving the viper just smokes the heck out of the tires) but I witnessed over the weekend, a 2003 Cobra with Cat-back exhaust and the pulley upgrade put 502 horsepower to the rear wheels and 506 torque. And just yesterday I read in muscle mustangs and fast fords that just changing a stock cobra's exhaust to cat back exhaust and K&N air filters, the car dynoed 50 more horsepower to the rear wheels and 44 more torque. So for about 1000-2000 dollars a Cobra could probably run with if not faster than the SRT-10.But I still like the viper alot better.

Sax1031,
I happen to own a 2003 Cobra as well as a GTS Viper, and while the Cobra performs well on the dyno (mine pulls 400 rwhp SAE with just catback, X-pipe, and K&N filter), I find real world performance not to be commensurate with those kinds of dyno numbers. E.g., my best trap speed is 109 mph, and my best ET is 13.2. Admittedly, that was based on only one day at Carlsbad, which is a notoriously bad track for those with street tires (on the F1's, my best 60' time was 2.2), but still....I would've hoped for higher trap speeds at least.
Bottom line: don't kid yourself. With $1000-$2000 in mods, you're looking at 500 rwhp and low 12's on the Cobra unless you get some stickier rubber. Then mid-to-upper 11's. Meanwhile, the SRT will run mid-11's on street tires and low-11's on ET streets. But of course this is speculation to some extent since the SRT isn't even out yet, despite that thread on SVTperformance.....
