Kevin and Willie are stoked when one of the quickest SUVs in the world rolls into the shop, the Jeep Trackhawk. They'll take the supercharged Hellcat V8, with its factory 707 horsepower, and give it an extra boost.

Kevin helps a veteran buddy get his bike ready for Biketoberfest. They'll wet blast some of the bike and properly lay paint on it. Then it's back to Detroit one more time to dyno Kevin's completed ARP Coyote engine build.
