Here's the view from the passenger seat of the Q650. Even driven sedately, because of the marginal track conditions, the car's acceleration and handling were breathtaking.

The Adaptive Performance Calibration is designed to work seamlessly with the Steeda's new high-efficiency Whipple Gen II supercharger. If you followed our recent series dealing with the myths surrounding superchargers, you know that a blower at fifteen pounds of boost can effectively double the horsepower of your engine. Even more important, it works throughout the rev range, unlike a turbo that must spool up or nitrous that works only during full throttle bursts. Forced induction is nothing new at Ford. It was a favorite way of increasing horsepower and goes back to the flathead days when a McCulloch Supercharger was fitted to '37 Ford 85hp engines, taking them to a neck-snapping 124 hp! McCulloch centrifugal superchargers were used in the '57 Thunderbird F-models, resulting in an impressive 300 hp. Shelby added a Paxton blower to his '66 Mustangs to keep them ahead of the competition. Today, with increasing government regulations and corporate average fuel economy (CAFE) standards forcing auto manufacturers to downsize engines and vehicles, supercharging is the best way to create increased torque and horsepower throughout the rev range.

Steeda's research, using more than 100 parameters and its own custom designed data acquisition system, has led to a Whipple Generation II Twin-Screw supercharger that flows more air, operates at a lower temperature, and has less parasitic drag than any other supercharger on the market. The carefully designed 3/5 rotor profile maximizes low-end torque as well as top-end horsepower. The precision-cut helical gears mean whisper-quiet operation, the cast-aluminum housing allows for more effective heat dissipation, and the advanced seals have 100,000-plus-mile reliability. The combination of the Whipple forced-induction system and Adaptive Performance Calibration gives you the best of both worlds, with approximately 600 hp available. Add the Steeda Hardware Kit Upgrade (105mm MAF, 60 lb/hr injectors, revised supercharger intake, and oval throttle body) and you can expect more than 700 reliable horsepower. If your Mustang already has a blower, you can still experience all the horsepower and protection benefits from Steeda's Adaptive Performance Calibration since the versatile package works with any supercharger on the market.

The Steeda Spec Racer is designed to compete in SCCA Pro 1 category. It begins with a stitch-welded body in white and uses parts from the Steeda catalog. It will produce between 650 and 700 hp. Helping to plant that awesome power are fully adjustable Tokico struts and a new Watt's linkage that allows simplified raising or lowering of the car's roll center. Up front, the car has a new heat exchanger which is 130 percent more efficient. Both the air dam and the rear wing have been wind tunnel tested for aerodynamics.
