the mustangs come straight from fords auto alliance plant. they come to you as the purchaser ready to race. including the sealed 5 liter engine. they must run the factory supplied computer, and an air intake restrictor, whereas the camaro runs no intake restriction, is allowed a bosch computer(i though that they came with bosch computers, but the rules specifiying this tell me that they're allowed to use an aftermarket one)

you can walk down to ford, order part number M-FR500-BOSSR1, and you will have a complete mustang ready to race(minus fuel, spare tires, and a professional driver of course).
on these cars, virtually the ONLY thing not built at the auto alliance plant, is the cage.
these mustangs come down the very same assembly line that your neighbors gt will come down. to a point. then it's pulled off, shipped down the road for the cage install, shipped back to the auto alliance plant, where it is assembled the rest of the way by hand.

everything i've been able to find on the camaro gs-r, is that you have to purchase it from chevy, then ship it to riley racing, and they do the race prepping on the car. that's not production.

i wish i'd have seen this post while i was still at home.....for some reason youtube won't open videos on my work computer......i'll have to wait till tonight.

i should add....i think that both the gt500, and the zl1 are amazing cars. the only things i can't like about the zl, are those stupid looking offset rectangle openings below the bumper, where the foglights are. they kill the nose of the car.

Anyway you are using a little bit heavier C6Zand a little bit lighter GT500 that I am. But small variations in weight +/- 20lbs to account for slight differences (ie. ~0.4 or ~0.5 lb/hp) kinda supports my feeling that the margins are small. A full vs. empty tank of gas could swing the weight 50lbs. Anyway, my weight numbers are from Edmunds, though I do know my own C6Z came in at 3181. Granted the '12 could be a bit lighter than the 2011, but I dont have official curb weight specs.

But more importantly, beyond the specific cars in question, when you get into the realm of mid 11s or faster it takes more and more horsepower to gain less and less ET and trap speed, the relationship is less linear as well as other dynamics having a larger effect as well. The difference between a 13lb/hp car and 12lb/hp car is greater than the difference between a 9lb/hp and a 8lb/hp car despite both having a 1lb/hp difference. Im pretty sure you know this, but that is really why I think ~0.4 lb/hp is a slim margin... Not insignificant necessarily, but well within the proverbial "drivers race".

However, the over rev feature does change things I suppose, but how does the feature work? Can it over rev every gear in every situation? If so, and if the over rev feature can be used at will when one pushes it to 7K, then why not just advertise the redline and hp accordingly? If it is like the temporary overboost on some turbo cars then that is has its own considerations too, but I digress...

At any rate not arguing per se, just walking through my reasoning. I dont care enough to turn this into a C6Z comparo since I think the true glory days of this car was 3 or 4 years ago anyway, back when the GT500 still was anchored by an iron block engine. Besides, I agree with the fundamental point that the 2012 GT500 will run 11s anyway.

I see ur points now and i must say i agree.

Curb Weight/Distribution/Rear Tire Size

2013 Mustang GT 500:

3820 lbs; 56%/44%; 285/35ZR20

2012/13 Corvette Z06:

3199 lbs; 50%/50%; 335/25ZR20 - Michelin Sport Cup (available)

Power-to-Weight is only ONE stat and, if it can't be adequately transferred to the rear wheels, or is applied through less-than-adequate tires, very sophisticated electronics will need to be utilized.

Regardless, an aweful lot is going to be asked of 285 tires...

...and not many folks purchase a Z06 solely to drag race...

ive seen people work wonders using 275mm tires. Im sure 285's. Something larger would be nicer but not necessary IMHO.

it's kind of nuts comparing the gt500 to a vette. vettes are in a class all their own for the most part.........

You're absolutely right...on DRAG RADIALS...

...in fact, in the current issue of Hot Rod Magazine, there's a street-driven FORD PINTO that ran an 8.02 (!!!) on 275 Drag Radials... Yup...with a Chev LS-series engine...the REAL "magic ingredient"...!!!!!!!!!

that's true. the gt 500 is quite inferior.

maybe they figured the ford engine would overpower the tires too much

Just how far is TROLLSVILLE from San Jose? When did you move there?

DUDE....nearly everything is inferior to a corvette.......but if we compare the gt500 to the zl1......the gt500 wins.
