Twin-Screw Voodoo

Riding shotgun in the first Whipple-boosted 2016 Shelby GT350

By Steve Turner

A push of the red button and the Voodoo 5.2 comes alive. The exhaust burbles and rumbles through fully opened mufflers. It’s not until we pull away with some more generous application of the throttle that the true nature of Lethal Performance’s latest project reveals itself. Yes, this is a 2016 Shelby GT350, but as its free-flowing pipes expel the burnt E85 there is just a hint of something else under the hood—a 2.9-liter Whipple supercharger.

Regular readers know that Lethal recently became the first outfit to supercharge the new Shelby’s Flat-Plane-Crank 5.2-liter V-8. This was not without trepidation, as many postulated that this high-winding engine could never survive having something added to its carefully balanced front engine accessory drive, much less being being boosted. As we now know, it readily accepted over 11 pounds of boost and produced over 800 horsepower at the rear wheels.
