We sit down with John Hennessey (@HennesseyPerf) to catch up on Hennessey Performance's new builds to commemorate their 25th Anniversary, including an 804 horsepower Mustang, Dodge Challenger SRT Hellcat with HPE1000 Twin Turbo/Supercharged Engine Upgrade proudly painted in Shell yellow, and VelociRaptor 6X6. We also hear about Hennessey's new Tuner School, a 14-week program for the young who have the dream and passion to learn a variety of modifications.
