A twin screw supercharger kit. A 3.0L belt driven blower replaces the factory intake manifold and pumps air into the engine. Twin screw units are positive displacement, so boost comes on low in the rev range instead of building with rpm.
why this one — The highest published output of the superchargers here, up to 595 horsepower and 570 lb-ft on 93 octane, and this is the version built for the Global B computer used in 2023 and newer trucks. It is also the priciest, and you still have to buy a PCM unlock service from HP Tuners before it will run. Trucks 2022 and older take the WK-1210 kit instead.
Whipple's own product page for this SKU states "Up to 595 HP and 570 lb-ft of torque on 93 octane" - a TOTAL output figure, same published number as the Global A WK-1210 kit.
