Hmmmmmmmm - Do you guys smell that? I call Shenanigans.
No way dude, not even in the SRT8. You see, I've unfortunately raced one, so I know what they got. Even though you have 50 (or so) more horse than I have (Sublime), our power to weight ratio just doesnt add up to be racing cars with 550+ horse and weigh 1000 pounds less. Shenanigans.
The difference between the SRT8 and the Daytona at speeds over 100mph is large. You can not use your experience in a Daytona and extrapolate that out to a SRT8.
That being said, I agree with you that if a SRT8 hung with a 997 Porsche Turbo the guy either couldn't drive or wasn't really trying. Now if it was an older Turbo then that is a different story.
