When it comes to our Mustangs, and their performance, we sometimes get impatient with wanting more power. We want it, and 5 minutes is too long to wait. We want it now.

In the case of Lethal Performance’s Jared Rosen, he has used his Mustangs as calling cards for several years now. He uses them as test mules to see what works and what doesn’t, so his company can pass that information and knowledge on to its customers.

In the case of his Performance Pack ’15 Mustang GT, Rosen is not one to sit around, and when Whipple unveiled its ’15 Mustang GT system, it was a foregone conclusion that the car would have one on it, and very soon. Lethal is Whipple’s largest dealer, and whenever a new model comes out, Lethal is quick to give it a whirl.

Lethal Performance’s ’15 GT wears a custom wrap applied by Kauff’s Wraps and Tints in West Palm Beach, Florida.

Lethal, with installation help from its performance shop of choice, Power by the Hour, and tuning by Lund Racing’s Ken Bjonnes, has the car making  805 hp and 618 lb-ft of torque using VP Racing Fuels MS109 fuel.

The supercharger is Whipple’s 2.9L twin-screw, front feed supercharger, but to help the car make that power, it also benefits from Whipple’s billet throttle body upgrade, a JMS Chip and Performance PowerMax FuelMAX fuel pump voltage booster, ID1000 injectors, and an ARH exhaust system. Support equipment includes a McLeod RXT clutch, a Barton shifter, and Driveshaft Shop 1,400hp half-shafts and aluminum driveshaft.

At Palm Beach International Raceway, Redline Motorsports’ Jeremy Martorella piloted the car to a 10.33 at 134 mph with a 1.55 short time on Race Star wheels wrapped in M&H 18-inch drag radials.
