Whipple Supercharger Kit

11-14 Dodge Challenger 6.4L SRT8



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 engines. With over 30+ years of twin-screw supercharging experience, Whipple’s team have now engineered the most powerful supercharger system available today for your Hemi engines. The all new, Gen 5 supercharger systems feature the latest patent pending dual intercooler, dual pass technology for industry leading cooling capacity, massive 112mm high flowing inlet, Gen 5 3/4 rotors and upgraded belt system to give you the most advanced upgrade available today. More power per pound of boost with neck whipping torque and ear to ear grinning top end horsepower, the Whipple Supercharger system is absolutely a beast!
The all-new Whipple Gen 5 supercharger system features the same technology that Dodge uses for its factory built Drag Pak program and is helping teams set new records nearly every race weekend. Not to be confused with the Gen 3 or 4, this all new supercharger features industry leading efficiency from idle to redline. All new bearings, gears, rotors and housing allow the new supercharger to spin faster, longer and safer while producing more power than any other positive displacement supercharger ever built. The new Gen 5 features an all new 3/4 rotor combination vs previous 3/5, 285 deg helix vs previous 270 deg, new bell mouth inlet, optimizied dishcarge port and increased diameter vs length for higher efficiency.
The Whipple Supercharger system features new, high flow fuel injectors, billet fuel rails, oversized heat exchanger, high flow intercooler pump, all the pre-formed and fitted hoses and all the necessary wiring connectors for a easy installation.

Model years 2015-2022 require unlocked PCM's. Whipple includes HP Tuner unlock code with supercharger system purchase. PCM must be shipped to HP Tuners for unlock service.

Model years 2018-2021 kits include security gateway module to allow for reading/writing PCM.


Boost is for reference, results may vary from application to application.

No other upgrades required, just massive power right out of the box

  • Front entry W175ax (2.9 liters) Whipple twin-screw supercharger that significantly outperforms competitions 1.9L and 2.3L roots-type systems

  • Front feed supercharger utilizes precision ground helical cut gears vs a problematic belt or shaft through the inlet that causes massive VE loss

  • Massive high flow cold air intake system included

  • Integrated Crusher™ 109mm round inlet outflows smaller 90 and 93mm inlets such as other Eaton based systems

  • Integrated Crusher ™ 109mm round inlet for optional oversized throttle bodies

  • Integrated design allows for oversized intercooler core compared to other smaller intercooler cores giving Whipple lower air charge temps which allows more boost and timing to be run on pump gas

  • Massive air-to-water aluminum bar-plate intercooler offers more cooling than any other positive displacement system available

  • Massive aluminum intercooler reservoir holds more than double the IC water than any of the competitors, more water, more power

  • Industry first billet auto drip oil catch-can system using factory quick connect fittings

  • Whipple Superchargers massive oversized intercooled air-bypass system for industry leading reduction of burst knock and incredible fuel economy, no ridiculous fabbed steel tubes or systems that circulate hot air

  • Self-contained oversized oil system for dramatically reduced oil temps in even the most demanding conditions

  • Exclusive 3x5 rotor combo for significant increase in airflow under the curve than less efficient 4x6 rotor combo

  • One-turn turn inlet allows for decreased induction losses when compared to rear inlet systems and 180deg bends

  • Center discharge port for better cylinder to cylinder distribution then other twin-screws with cobbled together billet adapters and forward facing discharge

  • Discharge down design allows for less pressure loss which gives more power at lower boost levels

  • Top mount design allows for cooler operation then upside down SC's that conduct heat from engine and are trapped by runners and covers, causing hotter manifold temps and less power per pound of boost

  • More boost at the "hit" than any other twin-screw

  • Flat torque curve for incredible acceleration

  • MSD™ Fuel pump booster with pre-defined voltage curve for less pump duty cycle then other pump boosters, only supplies increased voltage when needed, others are on/off

  • MSD™ Fuel pump booster voltage curve can be adjusted by user, no need to purchase "competition" version, already included

  • Oversized heat exchanger for incredible intercooler water temps

  • No internal engine modifications required

  • Completed installation looks factory installed

  • Kits come complete with all necessary parts and hardware for installation

  • Unique oil level sight glass for easy oil level and quality check, no dipstick to bind or misread

  • Plug and play wiring with male and female connections

  • High flow air filter system featuring a S&B True flow filter

  • High flow fuel injectors included

  • Proven 6-rib belt system with adjustable idler system for easy belt changes and multiple pulley configurations

  • Stainless steel jack-shaft with unique plastic cover (or optional carbon fiber) for increased safety

  • OEM quick connect fittings for easy installation, no ugly brass or steel fittings on the SC

  • Complete kits, Tuner kits and Hot Rod kits are available

  • Available in wrinkle black, polish or any custom color

  • Easily upgradeable with big cold air intakes and bigger throttle bodies

  • Instant boost at the touch of the throttle

  • 3 minute pulley changes

  • SCT Flash tool that allows you to read and erase codes and multiple data log features

  • 1 year warranty

  • Optional 3-year 36,000 mile powertrain warranty
