Whipple GM LSX Rear Feed 4.5L Supercharger Intercooled Hot Rod Kit w/ 12 rib W275AX

WK-1840
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.

Description

There are many options available for Whipple Supercharger kits. If you have any questions please email sales@TREperformance.com or call 760-586-5617.

Since 1987, Whipple Superchargers have been the pioneers and leaders of twin-screw supercharging. Whipple was the first to bring positive displacement technology to fuel injected, emissions legal GM applications. With over 26 years of GM twin-screw supercharging experience, Whipple's team have now engineered one of the most powerful intercooled twin-screw SC system available today for your LS based engine. Whether you have a LS1, LS2, LS3, LS6, LS7 or anything in between, Whipple has a front entry universal SC system that will work for your hot rod, sand rail or whatever other application you need neck whipping power for.

The unique intercooled bypass system offers better acceleration and less than 1hp of consumption during cruising for excellent fuel economy. The new system is very modular, offering many different belt system and cylinder head options. While others claim, Whipple Superchargers simply deliver more power per pound of boost than any other supercharger on the market today.
