Whipple Superchargers Gen4 head units are now standard on all 2.9L supercharger kits
Whipple is always pursuing the latest & greatest technology and making any innovation they can to produce the most efficient supercharger on the market. The 2.9L supercharger has been the most popular head unit for the Cobras, GT500s and Coyotes. For this reason, Whipple has focused on improving the rotor & housing design of the 2.9L.
Whipple introduced the Gen 3 rotor upgrade for the 2.9L in late 2017 and it boasted a 30-150hp/tq increase at the same boost level compared to its predecessor. It’s been performing like a beast but Whipple knew they could get more out of the 2.9L so earlier this year they introduced the option to upgrade to the Gen 4 rotor & housing. The Gen 4 upgrade is great for those customers wanting a little extra hp boost but without going full Crusher or crazy small pulley setup. The step up from the Gen 3 was not as big as the 2-3 step, but still makes for a nice little gain. Compared to the Gen 3, the Gen 4 2.9L has a 4% flow increase and will make around 1-1.5 more psi at the same pulley size.
- Adds up to 30-150 hp/tq at the same boost level
- 10-80*F cooler temps
- New Whipple Crusher SC Housing for increased volumetric efficiency
- Simple bolt-on upgrade to existing Gen 1, 2 and 3 2.9L/W175AXFF superchargers
EGR and Airbox Assembly Included
TUNER / COMPETITION KITS DO NOT INCLUDE TUNING
If your craving more power from your Lightning or Harley truck, Whipple has the answer. Get the industries most efficient and latest designed twin-screw supercharger. The new Whipple system can produce incredible power levels with stock 5.4L Lightning engines as well as highly modified engines. The revolutionary new W140ax compressor has the ability to run nearly 25lbs of boost (engine modifications required) for unheralded performance.
This direct bolt-on replacement system dramatically lowers supercharger air temperatures and power consumption (hp) versus the factory Eaton roots-type supercharger. The complete bolt-on system comes with all the necessary parts for 12lbs of boost, large mouth inlet casting, high-flow cold-air intake system with massive S&B True Flow 9” filter and all as the necessary parts for a simple installation. The Whipple system accommodates both factory and aftermarket throttle bodies and there’s no need to clearance the firewall or hood in anyway. Using a clean sheet design, Whipple used the rear axial entry design vs the factory axial/radial version that sacrificed drastic performance. The Whipple axial entry reaches nearly 99% VE during its operation, significantly outperforming the stock supercharger.
Other companies make false claims and inaccurate judgments regarding supercharger efficiency and kits. It’s a simple fact that the Whipple Supercharger produces more air per rpm at lower temps and lower parasitic losses.
