Alright...now here is what is detrimental to your argument. Say you take these cars and run them from a roll. Who decides what roll speed to run at? A 2nd gear 40-roll (or whatever) may put one car right into its sweet spot, where it may put the other above or below its peek torque/horsepower figures. You've got to keep in mind. These cars are geared differently to pull different weights, push past different drag coefficients and to perform at different levels and different top speeds. The Blown GT’s power curve is much different than the N/A Z06’s. Like all Positive Displacement blown cars, it makes ungodly torque from a very low RPM and softens as the RPM climbs, so wouldn't it make sense for Ford to gear the car accordingly? Why do you think the GT runs at over 210mph? Sure if you wanted to make things totally equal, you could gear the cars the exact same, but then what? You get a factory 10-second GT that’s nearly unmanageable to drive in a strait line on anything but slicks, but cranks out a 198mph top speed to match the Vette, or you get a Z06 geared to run the same (or as close as it’s power level allows) 214mph top speed as the GT, but won’t run better than mid/high-12’s because of it’s now running far too tall gearing. Doing this would take away from the balance of either car, which is one of the very many things they’re both praised for.
So, going from a roll which puts the GT at an initial disadvantage at one RPM may give the win to the Vette and visa versa. So what....does that prove that the Vette is a faster car? We already know that it's not and the GT has a
significant horsepower and top speed advantage over the Vette. So why shut down when roll racing at all....why not run them right on through until they quit pulling? Wouldn't that prove in fact "which is the
faster car"?
You're right.....drivers skill “could” hand an advantage over to one driver over another when going from a dead stop, but with equal drivers and conditions, this advantage is all but gone and it’s up to the sheer power and balance of the vehicle to prove the victor. When roll racing, the advantage is going to go the guy that chooses to race from an RPM and speed where his car is going to perform at its best. Fact of the matter is, is that when going head to head, if he’s smart, the Vette owner is going to want to go from a roll every single time! This is where he’s going to have the best chance of winning. Let’s face it, as good as the Z06 is from a dead stop, the power advantage of the blown 5.4L in the Ford GT just makes it better. Whether it be a quarter mile or 2-mile race. The only way a victor can truly be determined between the two is to run them from start to stop.
