Topped with Whipple's largest screw blower and capable of more than 1,000 flywheel horsepower while operating on its race-fuel tune, Stage 6 No. 014 has a squeaky-clean factory look underhood, thanks in part to its black-powdercoated Moroso coolant and intercooler tanks. This thing is all about deep breathing and precise calibration.

A trio of AutoMeter Nexus gauges are mounted in the stylish individual nacelles of Speed of Sound's A-pillar replacement, along with a Raptor mini shift light. Speed of Sound also makes the three-switch console panel. The pistol-grip is from Hurst, though it commands a Steeda Tri-Ax shifter.

Bet you're thinking that all this nitrous helped generate the huge power numbers. Wrong. The engine never sees the giggle gas; instead it's used to actuate the ARB Air Locker in the rear axle, which saves having an onboard compressor. Cool idea. Speaking of cool, the spray is also used to rev up bystanders as it purges through the snake in the grille.

Stage 6 exterior mods include the subtle but distinctive step of smoothing and painting the GT500's mirrors, side skirts, and rear diffuser in body color. The KR-style hood and painted stripes on Mike's Torch Red ride are just a couple of Evolution's numerous available options. Standard Stage 6 cabin upgrades include Auto Meter's innovative Nexus fuel-pressure and boost gauges; Mike also opted for a wideband gauge and remote gauge controller. His Speed of Sound console switchplate controls Evolution's line-lock system, and includes a purge button to send red-illuminated nitrous vapor hissing out through the grille-mounted snake emblem, and a third switch to arm the rearend's ARB locking differential, also by way of nitrous instead of compressed air. By the way, Evolution's lead technician, Chuck Wresniewski, gets credit for the trunk's beautifully crafted nitrous hardware and serialization plate. Oh, and we need to point out that the engine itself sees absolutely none of the giggle gas.

To show that it isn't just a haphazard assemblage of random parts, Evolution serializes each of its striking Stage 6 Shelbys, and Mike's is the 14th of the series, having rolled out the door in December 2008. He seems more than pleased with his investment and relishes having what is surely one of the most handsome and fearsome GT500s in the state of Nebraska. As for Evolution, word has it the company is now working on a Stage 7 package, which promises to be just as revolutionary.
