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.
Shelby saw the opportunity to improve upon this awesome off-road beast and decided they could make the Raptor a little more aggressive for off-road use. In 2013, they introduced the 575hp Shelby Raptor which had us drooling instantly. It was equipped with a supercharger, Method wheels and BFGoodrich Mud Terrain KM2 tires. Needless to say, Shelby stepped up the off-road game but like any true horsepower junky, sometimes you just need to give it a little more power.
The 2015 is comfortable and nimble on the street. It has good power and a great sound too. We were anxious to get on track, do a real burnout, and launch on a prepped surface. What we found is that the 2015 Mustang is tricky to launch compared to the out-going S197 Mustang. Why? In layman’s terms, the live axle in the S197, which is considered somewhat crude, provides great feedback for drag racing. The three-link suspension does a fantastic job of planting the tires and transferring the torque loads to the body to create pitch rotation (nose lift) to transfer weight from front to back. The heavy axle assembly also gives lots of feedback to the driver and really communicates what the tires are doing.
To get started, select “Line Lock” in the Track Apps and follow the prompts. Once engaged, you get 15 seconds to smoke the tires—but you probably only need a third or half that time to get the job done. Be sure you have the engine revved above 4,000 when you dump the clutch; this will prevent the engine from bogging and overloading the clutch.
