Whipple Cranks Up The Boost With Its Gen 3 Twin-Screw Blower

We believed there was a product evolution that needed to happen. — Dustin Whipple, Whipple Superchargers

If you are an ardent fan of the Coyote engine family, you have definitely seen some of these engines making crazy power running low e.t.’s thanks to the addition of a Whipple twin-screw supercharger. The company’s 2.9-liter blower is a popular option for power-mad members of the pack. In the world of performance, however, companies must innovate to lead. That’s why the company is releasing the Gen 3 supercharger.

But why change the wildly successful 2.9-liter supercharger? Well, like many markets, change is omnipresent, so keeping up with the performance demands of modern engines and consumers is definitely a wise strategy.

Available as a direct replacement for Gen 2 blowers or as a component in a complete Whipple Superchargers kit, the Gen 3 twin-screw unit offers a significant increase in performance for a modest up-charge. (Photo Credit: Whipple Superchargers)

Available Applications

• 2003-2004 SVT Cobra

• 2007-2014 Shelby GT500

• 2011-2017 Mustang GT and F-150

• 2010-2014 6.2-liter Raptor/F-150

“We have been using the Gen 2 successfully for nearly nine years, but we believed there was a product evolution that needed to happen to continue its success in the future,” Dustin Whipple, Vice President at Whipple Superchargers, explained. “The Gen 3 features new rotors with precision, robotically sprayed, conformal PTFE coating that adapts to the application and clearances needed. The rotors also feature a profile change, along with tighter tolerances that minimize power consumption and leakage. The updated rotor housing features revised port timing and bearing shape for increased rotor filling, along with a new, angled rib pattern for a more aggressive look.”

Whipple designed a new case and a new rotor profile to improve upon its successful 2.3-liter supercharger to create the Gen 3. The rotors are stronger, supported by more durable bearings, and coated with an innovative, robotically sprayed conformal PTFE coating that adapts to the required clearances.

Those are just some of the highlights that set this 2.9-liter supercharger apart from its Gen 2 predecessor. Not only does this new twin-screw have new rotors and a new case, it is built for better efficiency thanks to a new rotor profile.

You can distinguish the Gen 3 blower from its predecessor by these aggressive, angled support ribs on the case. This new housing isn’t all looks, however, the new case features a new port shape designed to fill the rotor with more air and decrease turbulence. All these changes combine to offer improved efficiency and power output at equivalent boost levels.

High Efficiency

On The Dyno

As mentioned elsewhere in the story, Whipple relied on extensive internal and external testing to prove out the efficacy of its new Gen 3 supercharger. Putting the new rotor pack and case design meant doing back-to-back testing with all the same parameters, including the calibration, boost level, and timing. Its internal testing revealed solid gains of 30-40 rear-wheel horsepower on California’s weak-sauce 91-octane fuel.

For its outside testing, Whipple turned to Tasca Performance. As you can see in this dyno sheet, Tasca ran the Gen 3 on a completely stock Mustang with no other changes besides the head unit and picked up an impressive 51.65 horsepower and 56.18 lb-ft of torque at the rear wheels.

Combining the more efficient rotors with an new Crusher case design designed to further improve volumetric efficiency, the Gen 3 Whipple is said to run anywhere from 10 to 80 degrees cooler than its predecessor. It is also more efficient and creating more power.

“During extensive testing on multiple applications, both Whipple and third-party testing found gains from 30 up to 150 rear-wheel depending on blower speed and engine specifications,” according to Lethal Performance. “Standard pump-gas applications can easily make another 30 rear-wheel horsepower with no other changes. Because boost maintains, tuning is not required. Just bolt it on and unleash the power of your stock application.”

Sounds like a plan. The Gen 3 Whipple superchargers are available as just supercharger head units for those who want to swap out just a blower for increased performance. They are also available as part of complete kits at a $200 premium over a Gen 2 head unit.
