Custom dyno tuning is required for operation. Does not include fuel system upgrades (injectors) or programmer.
Whipple Technology. The most efficient twin-screw supercharger on the market, the Whipple W140ax 2.3L supercharger significantly outflows the competitions 1.9L roots-type superchargers. Whipples top mount design allows for cooler operation when compared to upside down superchargers which tend to trap engine heat causing hotter manifold temperatures and a loss of power. Whipples discharge down design allows for less pressure loss which gives more power at lower boost levels. Using an exclusive 3x5 rotor combo for a significant increase in airflow under the curve, this Whipple Supercharger is much more efficient than other companies 4x6 rotor combo. Whipple Superchargers feature a massive oversized intercooled air-bypass system for an industry leading reduction of burst knock and incredible fuel economy.
Application. This Whipple W140AX 2.3L Intercooled Supercharger Competition Tuner Kit; Black is designed to fit 2004-2006 GMC Sierra 1500 models equipped with the 4.8L V8 engine.
