Whipple Launches Supercharger For GM's 6.6-Liter V8

The new system uses Whipple's fifth-generation twin-screw supercharger, aluminum high-flow intake manifold, billet idler plate and adjustable idler system, and a complete intercooler system. The latter is an oversized air-to-water bar-and-plate with billet aluminum tanks and high-density fins. Whipple also includes a dual-pass heat exchanger to keep things cool under heavy loads. According to Whipple, this unique system offers "better acceleration and less than [one horsepower] of consumption during cruising for excellent fuel economy."

Each system is finished in a standard textured black, but Whipple says it can be ordered in nearly any custom color. The kit is also sold with an HP Tuners RDT flash tool, which can be used as a data logger and for tire/axle adjustment.

For an additional $1,000, you can also add the Global A E93 PCM Upgrade and RDT Tool, including full support from HP Tuners. If you opt for the cheaper package, you'll get a voucher from Whipple for the required PCM upgrade from HP Tuners.

The system costs $7,495, plus $1,000 if you want the HP Tuners tool mentioned above. If you want to add color or contrast, you're looking at $500-$1,500 extra.

It's a lot of cash but still cheaper than the roughly $10,000 required to upgrade a GM HD model from the 6.6-liter gas V8 to the 6.6-liter turbodiesel V8. Still, with the diesel, you get 445 hp and a whopping 975 lb-ft of torque. That makes it thetop choice for towing and hauling.
