Confirming chatter on the forums at, Toyota Racing Development has released specs for its all-new 5.7-liter V-8 supercharger, which fits perfectly under the hood of the Toyota Tundra half-ton pickup.

The roots-type compressor boosts horsepower from 381 to 504, and torque goes up from 401 pounds-feet to 550 pounds-feet. Boost pressure is a heady 8.5 psi.

The supercharger is compatible with Tundras from the 2007, 2008 and 2009 model years.

TRD superchargers installed by an authorized Toyota dealer carry a 12-month, unlimited-mileage warranty, or the balance of Toyota's new-vehicle five-year, 60,000-mile powertrain warranty, whichever is greater. Installations not performed by an authorized Toyota dealer are covered by a 12-month, 12,000-mile parts-only warranty.

MSRP for the supercharger kit is $5,875 (about $48 per additional horsepower). It includes two components: the main assembly kit and a supercharger fit kit. Labor is a separate cost, subject to dealer pricing and rates.
