Once in Fourth, all that’s left is to ride it out. With 3.73 and a few mods, it may be necessary to upshift one more time into Fifth. This always makes us nervous because we don’t want to mess up the last shift, plus Fifth gear can be fragile and we don’t want to break the trans. Our test car did not require shifting into Fifth, but we’ve had to do so in 2011-2014 5.0 Mustangs.
A set of Rouge Racing upper and lower control arms offer a heavy duty suspension package that can hold up to the stresses of high-speed off-road jaunts while a set of King 2.5-inch coilover remote reservoir shocks soak up the hard hits and smooth out the bumps. Out back, a set of King 2.5-inch bypass shocks keep the truck floating over the whooped out roads.
The Ford SVT Raptor is without question one of the ultimate street-legal go-fast off-road rigs you can buy and hit the dirt in. While the Raptor is incredibly fast in the desert, it leaves plenty to be desired on the table. Contrary to keyboard racers, the Raptor is not a Trophy Truck, but it was built to race—in fact, it did just that back in 2008 at the 41st SCORE Baja 1000. Of course this means that improving upon the performance of the Raptor is quite an uphill battle if you still want the truck to have decent road manners.
Certain models of the 2015 Mustang have Launch Control. You can use this driver aid or do everything yourself. Either method requires a cool head on the line and smooth release of the clutch. Once you’re staged, your adrenaline will be pumping and you’ll be itching to unleash all that power. Launching on street tires is tricky, so your full concentration will be required.
The suspension is a little on the stiff side but that’s to be expected in a car that is setup for the track. Trust us, you wouldn’t want a floaty suspension with 650hp on tap. Speaking of suspension, Shelby has really done their homework with the Shelby GT as we were able to carve around more than a few corners at speed while the car gripped the tarmac and took it like a champ.
We are pleased with the performance of the 2015 Ford Mustang GT. It takes time to get the best performance from any new combination, but if you utilize the driver aids such as Line-Lock and Launch Control, you’ll get up to speed quickly. Ford has done a wonderful job providing the necessary power and technology to make this one heck of a Mustang.
But more than the history and visual cues, the Scat Pack package is a nod to all the engineering and performance upgrades that must necessarily accompany a powerplant of this magnitude. Improvements over the 5.7L Hemi R/T Challenger include larger four-piston Brembo brakes, wider and taller 20-inch rubber, a larger-diameter 2.75-inch dual stainless-steel exhaust system, Performance Pages, aerodynamically enhanced spoilers, an uprated 3.09:1 limited-slip rear, higher-output 220-amp alternator, and High-Performance suspension. And except for Performance Pages, it’s all needed to safely meet the needs of the Scat Pack’s 177 mph top speed.
Dimensionally, the new Camaro is slightly trimmer in all exterior dimensions and notably in a nearly 2-inch reduction in wheelbase but the overall effect is more dramatic, particularly with almost fastback profile. It simply looks lean and taught.
In Launch Control mode, follow the prompts to set up your rpm. Once you’ve staged you can put the throttle on the floor and keep it there for launch, or for the entire run if you’re powershifting. When you step off the clutch to launch, the Mustang will do its best to give you maximum acceleration. Using Launch Control still requires a smooth release of the clutch to give you the best performance. While the system allows some spin, excessive spin will cause the computer to apply rear brake and kill a bit of power to regain traction.
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.
First came Hellcat, forever changing the gearhead meaning of the numbers “707.” Hellcat almost overshadowed what was arguably the more significant performance/value breakthrough—the 485hp Scat Pack Challenger and Charger. Nevertheless, it hasn’t escaped our attention, and we hope it won’t escape yours either.
The inside of the 2015 Shelby GT is just as impressive as the exterior with plenty of unique touches such as the Katzkin interior, Recaro bucket seats, Shelby 3-gauge dash pod as well as a Ford Performance Racing Parts Short Throw Shifter to help you bang through the gears with ease.
If you’re looking for a good elapsed time, shallow staging is a must. Prestage, stop, collect yourself, and then carefully inch forward until you barely turn on the Stage beam. I’ve seen lots of racers dump the car in both beams in one motion, which usually results in the car being “deep” staged. Since your time starts when your front tires break the stage beam, shallow staging gives you a running start on the timing system. Shallow versus deep can be worth as much as two-tenths of a second!
