While that's the story on Vortech supercharger availability for the '05 Mustang GT, this particular car is also worth examining. As the '05 Mustang used to prototype the Vortech package, the company also added some other goodies to make it more appropriate for the automotive-press spotlight.

Starting with a basic Deluxe-packaged five-speed car, the first step was to get the ride height down to give the car a more road-racy flair. That was accomplished with an Eibach Pro Kit spring package that resulted in about a 1.3-inch lower ride height in front and 1.4 inches out back. Tokico D-Spec struts and shocks were fitted to the car to complement the springs.

Also installed was a prototype Baer brake system, with Baer/Alcon six-piston calipers up front, along with a set of 13.5-inch two-piece EradiSpeed rotors. The rear rotors are 13-inch units. When Baer's production '05 Mustang system becomes available, 14-inch rotors that fit behind an 18-inch wheel will also be available.

With the stance of the car just right, Vortech went with a slick set of Ronal LZ Eleganz wheels, which measure 18x8.5 inches up front and 18x9.5 in the rear. Toyo Proxes RA-1 tires are wrapped around the wheels-245/40ZR18s in front and 275/35ZR18s out back. A pair of Bassani Quiet Thunder mufflers that fit behind the rear wheels on an '05 Mustang gives the car a nice, aggressive audio track (and some extra power along with the blower).

The wheel, tire, suspension, and brake updates make this '05 a solid notch or two more fun to drive than a stock Mustang because of its aggressive look. But factor in the blower and sporty sound emanating from the Bassani exhaust, and the fun factor really jumps. Why? Because a new Mustang, with all the inherent pleasures it provides, would be mated to pure big-block-like pull. When the gas pedal hits the floor, you'd get the same feeling a 428 CJ provides and then some.

"Then some" was proved when our colleagues at Motor Trend ran this car through their usual testing regimen on a 300-foot-diameter skidpad and a 600-foot slalom. The suspension and wheel/tire upgrade made a noticeable difference. A stock '05 Mustang circled the skidpad at .87 g and ran through the slalom at 65.4 mph. This car bettered those figures in fine fashion with .92g and 67.3-mph showings.

As for pure straight-line acceleration, a new supercharged Mustang will easily run and hide from any big-block vintage Mustang. Even on this car's Toyo street tires, the Motor Trend boys hustled this blue bomber to 60 mph in a scant 4.65 seconds on the way to a quarter-mile time of 13 seconds flat at 108.5 mph. And that's with the car's stock 3.55 gears. We'd surmise that with a high-output aftercooled Vortech kit, a pair of 10-inch slicks, a set of 4.10 gears, and a good driver, a supercharged '05 Mustang GT could possibly be an 11-second ride.

Any takers?
