Speaking of business, even though Evo's positive-displacement supercharger upgrades seem to do just fine on customer vehicles, the company is now marketing a twin-turbo kit for the GT500, though it bears little resemblance to the one on our feature car. And we suppose we should mention that Fred Cook says it makes a 1,000 hp on pump gas. Call 'em for details.

The Evolution continues...

Since so much of the Evolution Performance business plan now revolves around Shelby's GT500, it didn't take them long to get a 2010 project underway, a Grabber Blue street car to pair with its Grabber Blue racer. The new coupe is both a regularly driven street car by its owner Nelson Whitlock Jr. It is a regular competitor in NMRA's Modular Muscle class, and also serves to showcase some of Evo's rather lengthy shopping list of GT500 hop-ups.

Its power adder consists of the exclusive Kenne Bell/Evolution Performance Competition kit, consisting of a KB Mammoth 2.8H twin-screw in a black billet case, contrasting with a polished and engraved inlet, twin 75mm throttle body, 130mm Big Oval mass air housing, and black aluminum pulleys. The kit also brings a dual Boost-A-Pump, specific spark plugs, flow-matched 72-lb/hr injectors, and Evo's custom street and race tunes. Under 23 pounds of boost, Evo has dyno'd it at 861 hp and 792 lb-ft of torque at the tire.

Though it appears nearly stock on its street rolling hardware, the '10's chassis has also been attended to with Eibach springs, Tokico D-spec dampers; an upper control arm mount, adjustable third link, and lower control arm relocation brackets, all by BMR Fabrication; Steeda billet lower control arms, and Evo's own Panhard bar and brace.

The resulting well-balanced performance of Evolution's 2010 Shelby earned it an invitation to be one of our King of the Street competitors in Bowling Green last October. Since I'm writing this in early September, I'm curious to see how it does...
