2800lbs an 535hp seems good for low 11s maybe high 10s

I don't see why a car with 535hp and weighing less than 2800 pounds can't run 11's. I just threw those numbers into a calculater and it comes out around 10.7. Now granted those calculators aren't 100% accurate, but they are close enough to get an idea.

the car has only done an 11.3 at best

And you know this because.....

I am not saying that you are wrong, its just weird that they would publish a car and driver calendar that says it is well into the 10's if its not even close.

i think we need to find similar cars weight-wise and hp wise and see what they are running at the drag strip...

Yea I agree, it should probably be FWD too just to eliminate as many variables as possible.
