A supercharger is a belt-driven air pump bolted directly to the top of the engine that force-feeds it more air than it could pull in on its own.

why this one — Whipple's Gen 6 3.0L twin-screw kit is the T1XX-generation L87 successor, CARB certified and confirmed for both Chevrolet Silverado and GMC Sierra 1500, with a real, specific claimed number (up to 685 hp/655 lb-ft) rather than a vague pitch.

where the number comes from

Whipple's own product page states "up to 685 horsepower and 655 lb-ft of torque" on 93 octane at 7 psi boost for this kit.

heads up

CARB EO# D-231-143 per Whipple's own product page. Major forced-induction upgrade - expect a supporting-mods conversation and potential powertrain warranty impact.
