Every work truck needs a Whipple. We bolted a Whipple Supercharger system onto this 7.3L Godzilla F-250 to turn standard heavy-duty utility into real, effortless power across the entire rev range.

When a 2.9L Whipple fails, you don't replace, you upgrade. Dropped a 3.0L Whipple onto this 50th Edition Camaro to restore the platform and push the airflow potential even further.

Clearing out the restriction on this F-150. Upgraded to a Stage 2 Whipple with a custom sized griptec upper pulley and Kooks long tube headers. The port injectors were upgraded to Injector dynamics 1300s and fed pump E85 by the one and only Aftermarket Industries fuel system.
