You can feel slight chirping or slipping of the tires and apply power and clutch accordingly to get maximum traction and acceleration. The IRS provides excellent grip on launch, but it also reduces some of that feel because the tires are more isolated from the chassis. Because of this, it’s harder to feel exactly what the car is doing, which is important when you’re on the ragged edge of slip or grip. This forced us to drive more conservatively to find consistency. Of course, this wouldn’t be a problem with drag radials or slicks.
So how do you make the Shelby Raptor even better, how about slapping on King off-road racing shocks, all-new 35×12.5R18 BFGoodrich All-Terrain T/A KO2 tires wrapped around a set of custom 18-inch wheels and, oh yeah—stuffing a supercharger under the hood to give it 700hp.
The 2015 Shelby GT Mustang starts off with the very same 5.0L Coyote V8 from the Mustang GT but the similarities end there as the Shelby GT features a Ford Performance Racing Parts 2.3L TVS supercharger that bumps the power output all the way up to 650hp. You’ll also notice the unique Shelby aluminum caps on the overflow tanks that give the Shelby GT a little more sophistication under the hood. A Shelby cold air intake ensures the supercharged Coyote gets an adequate supply of air to let all 650 horses loose at a moment’s notice while a set of 3.73 gears allow the Shelby GT to get moving in a hurry.
We spent a week with this yellow screamer hitting all the local hot spots, including Bradenton Motorsports Park, home of the NMRA Spring Break Shootout. Our GT was equipped with the standard rear gear (not 3.73s) along with the Getrag MT-82 six-speed, and we ran the car 100 percent stock—so no drag radials or tune. Heck, we didn’t even cool the engine! Traction was good, but the temperature was 84 degrees with mild humidity—not mineshaft conditions, by any means, but not sweltering either. Based on our experience we were hoping to break in the 12s at about 110 mph.
