The current combination is the same, basic '03-'04 Cobra engine with beefed-up rotating parts, stock camshafts and valvetrain, and a Kenne Bell blower, but with a more reasonable 8 psi of boost, for an output of around 550 horsepower. It's still a potent combination.

"The car still makes all kinds of power and it's a blast," says McCombs. "It's better-suited to the track, because the power is easier to apply."

Note that McCombs said "easier," not "easy."

"When the boost hits, it hits hard," he says. "It's probably not ideal for road racing or autocross-type racing, but it's the combination we've got and with the Gateway suspension, the car bites hard and has been very competitive."

Indeed, the Mustang has been competitive enough to draw the interest of the producers of the new hit SPEED show "R U Faster Than a Redneck?" It pits modified American muscle against highfalutin' imports and with Jason Childress behind the wheel, the Mustang has already outgunned a Lamborghini. It's also taken a few runner-up places, which McCombs aims to change.

"We hadn't run the car for a few months when the call came about the show," says McCombs. "We only had about a week to get it ready. All things considered, we've done well, but I tell you, running Second time and again gets annoying."

And in true Hollywood fashion, the Mustang's knockout good looks reinforced its performance to land the part. The simple yet effective aesthetics—rooted in the black hood, R-type lower apron that shows off the enormous heat exchanger for the supercharger system and big, 18-inch Torq-Thrust–style wheels—give it a devastatingly serious appearance. It's clean and contemporary looking, with an unmistakable all-business stance.

McCombs and the Childress brothers are working to refine the Mustang's balance and trim a few pounds from the admittedly nose-heavy combination. Removing the power-assisted steering rack will help shed weight and they've already pushed the engine back a few inches in the chassis to improve the front-to-rear balance. Then again, the car is holding its own against modern sports cars and Pro Touring cars built expressly for competition.

"We've been very competitive in a car that was never envisioned in the first place to be a race car," says McCombs. "It's like a slot car and goes wherever you point it, as long as you can modulate the power."

It's also eminently streetable—a claim some of the more purpose-built Pro Tourers can't make. McCombs often drives to track events, competes and drives home again. And with the high power-to-weight ratio and the low cruising rpm delivered by the Tremec Magnum six-speed, this all-around performer has knocked down about 28 mpg on the highway.

"It's not a trailer queen. You can drive it every day. It's comfortable, streetable and, in fact, it's the most efficient vehicle I own right now," he says. "We've done the best on the track with what we have and it's been fun to be on the leading edge of a trend with these cars."

It's been a long journey from a six-cylinder secretary's car to a race-winning television star, but McCombs and the crew from Gateway have nurtured the career of this pioneering pro-tourer and are working hard to ensure it stays vibrant for the long haul, in the cut-throat world where racing meets entertainment.

To put it another way, think of this Mustang as the Meg Ryan of modified Mustangs, not a crash-and-burn Lindsay Lohan—that is, if they can keep it out of the late-night clubs and off the nitrous.
