If you want to go even faster than that in a Mustang, the only current options are the Boss 302S and 302R race cars, which may either fall below or exceed the expectations (and budget) of the weekend racer, autocrosser or time trial enthusiast. There may soon be a third, “just right” choice, as Ford showed a concept dubbed the Boss 302SX at the recent PRI trade show in Orlando, FL.
Meant to span the gap between the Boss 302S and 302R racers, the Boss 302SX gets an infusion of horsepower courtesy of revised tuning and the intake manifold from the Cobra Jet drag car. Output jumps from 444 horsepower in the stock Boss 302 to “over 500” horsepower in the Boss 302SX.
Mustangs Daily says the car borrows the heavy-duty six-speed transmission from the Boss 302R race car, and also benefits from an upgraded oil cooler, exhaust system and fuel system. It gets a fully adjustable coilover suspension, adjustable front and rear sway bars, camber / caster plates, Brembo brakes (with recalibrated ABS) and lightweight 18-inch wheels wrapped in racing slicks.
Inside, less is more. The Boss 302SX gets a lightweight driver’s seat, a six-point roll cage, a quick-release steering wheel and a data logging system for recording lap times. Like the 302S and 302R, the 302SX is for track use only, and can’t (legally) be driven on public roads.
The Boss 302SX is a concept only at this point, but Ford is paying close attention to feedback received from PRI show attendees. If enough express interest in the Goldilocks-of-the-Boss-Mustang race family, expect to see a limited production version in the not-too-distant future.
