With all the latest technology, the all new Whipple system makes more power than any other positive displacement supercharger system on the market giving you tire frying, neck whipping power that will give you a grin from ear to ear. The all-new system features Whipple's massive oversized air-to-water intercooler for unmatched cooling capacity, a unique rear feed W275ax (a whopping 4.5 liters) integrated Whipple twin-screw supercharger that reaches 99% volumetric efficiency and industry leading power potential. The 4.5L blower uses the better 8mm bolts for the supercharger pulley and runs a 12 rib setup, the 4.0L uses smaller 6mm bolts and a 10 rib drive. The 4.5L also has a better gear case which holds more fluid, keeping the blower cooler and making it more efficient than the 4.0L.

This kit includes only the supercharger and built-in intercooler and intake manifold system. No heat exchanger, piping, fuel system, or any other parts. Mechanical elliptical throttle body included, and will require the use of a mechanical throttle pedal assembly purchased separately. It is also recommended to run a standalone computer setup. Air entry must be placed on driver side. ATI balancer required. Usually the supercharger will fit under the hood and inside the firewall for GM trucks, but it is not guaranteed, some trimming may be required. The cowl in the back of the engine bay will most likely need to be trimmed. Photos are for example only, there are no available photos of the exact kits.
