Whipple HEMI Supercharger

Whipple Superchargers plans to release their all-new lineup of 2.9L twin-screw supercharger kits for the Dodge Challenger, Charger, Magnum, and Chrysler 300c in the coming months. Whipple, who has manufactured twin-screw blowers since 1987, has designed a 100% complete, bolt-on, and intercooled twin-screw supercharger system designed from the ground up for your 5.7L, 6.1L, or 392 HEMI engine. While the system was engineered with stock engines in mind, it has enough capacity to fully push a heavily modified Mopar motor.

The system features a massive air-to-water intercooler for improved cooling capacity and a unique front feed Whipple W175ax twin-screw supercharger, giving you a whopping 2.9 liters of displacement. The included W175ax reaches 99% volumetric efficiency and offers huge horsepower gains. Whereas the intercooled bypass system improves fuel economy and uses less than 1 horsepower of engine power when cruising. The kit also includes a set of high-flow fuel injectors, an aluminum high flow intake manifold, and a Whipple Power Flash Programmer from Diablosport to re-calibrate your factory ECU.

Whipple HEMI Supercharger Black Angled Whipple HEMI 2.9L Supercharger Features
  • Front entry W175ax (2.9 liters) Whipple twin-screw supercharger
  • Integrated casting to minimize bolt on pieces, adapters, leaks and flow restrictions
  • Integrated Crusher™ venturi shaped inlet for maximum airflow capacity and minimal rotor cavitations
  • Integrated Crusher™ 112mm round inlet for optional 102mm, 105mm and 112mm throttle bodies
  • Optional Crusher™ 120mm (4.75") air inlet system for increased air flow
  • Integrated design allows for oversized intercooler core, reducing charge air temperatures- allowing for more boost and more advanced timing, even on pump gas
  • Massive air-to-water aluminum bar-plate intercooler
  • Whipple Superchargers massive oversized intercooled air-bypass system in order to reduce burst knock and improve fuel economy
  • Self-contained oversized oil system for dramatically reduced oil temps in even the most demanding conditions
  • Exclusive 3x5 rotor combination for significant increase in airflow and under the curve power
  • Zero turn inlet allows for lower induction losses
  • Center discharge port for better cylinder to cylinder distribution
  • Discharge down design allows for less pressure loss which gives more power at lower boost levels
  • Top mount design allows for cooler operation
  • More boost at the "hit"
  • Flat torque curve for incredible acceleration
  • MSD™ Fuel pump booster with pre-defined voltage curve for less pump duty cycle, only supplies increased voltage when needed, unlike on/off sytems
  • MSD™ Fuel pump booster voltage curve can be adjusted by user
  • Oversized heat exchanger for incredible intercooler water temps
  • No internal modifications required
  • Completed installation looks factory installed

  • Instant boost at the touch of the throttle
  • Quick 3 minute pulley changes
  • 1 year warranty
Optional Upgrades
  • 112mm round billet throttle body
  • 120mm (4.75" diameter ID) cold air inlet system
  • Custom colors
  • Pulleys from 4.25" to 2.75" in every .125" increment
  • Optional 4.5 liter supercharger for race applications
Why Whipple Superchargers?

Whipple has been building twin-screw superchargers for over 23 years. Whipple's HEMI superchargers and other systems not only look like a piece of art, but they perform as well. The revolutionary front feed 2.9 liter (175 cubic inch) twin screw supercharger took over two years to develop every single component of this ground breaking supercharger system. The results speak for themselves, not only does it make the most horsepower, its fully upgradeable with camshafts, head work, throttle bodies, and bigger air intakes- so you have the ability to build a system from mild to wild to suit the needs of your Challenger or LX.

Whipple Front Inlet Superchargers

The Whipple front feed system offers less inlet restrictions. Furthermore, Whipple's front inlet design eliminates one intake bend, which promotes equal rotor filling and a higher overall volumetric efficiency. The system also incorporates a high-flowing, round, 112mm opening(flows nearly 1800cfm capacity or 1200hp) which will not limit your potential power gains. The optional competition inlet has only two bends.

Whipple HEMI Supercharger Orange Exploded. Whipple Fuel System

The Whipple Hemi supercharger kit comes with Siemens Deka 63 lb/hr fuel injectors that are rated up to 80psi of fuel pressure. These injectors give your 5.7L, 6.1L, or 6.4L / 392 HEMI engine the capacity for far greater power levels than standard systems. The Whipple 2.9L twin screw kit also supplies you with a MSD™ fuel pump booster. The MSD™ pump booster comes pre-programmed with a gradual curve, due to the fact that increased voltage is only required at peak boost levels. Additionally, the MSD™ fuel pump booster is also user adjustable allowing you to increase the voltage up to 22 volts, if required.
