Faster with Finnegan

Mike and his friends use their Roadkill ingenuity to try to add major speed to their '85 S-15 truck. When they're done wrenching, they'll see if it can beat Randy Pobst and a new Shelby GT350 Mustang around a road course.

The guys take on YouTuber, internet legend and drag racer Cleetus McFarland in a matchup for the ages. The small-block-Chevy-powered XJ12 Draguar goes up against a 1986 Ford Thunderbird that's been boosted with a 6-71 blower.

The Vette Kart has proven itself worthy on autocross, big track, dragstrip, sand dune and stunt courses. Now the guys are testing the Kart's rallying capabilities against champion drifter Chris Forsberg and a RallyPro Subaru WRX.

The guys and their big red K5 Blazer take on a local racer at the West Georgia Mud Park. After finding numerous issues with the Blazer, they decide the best way to add more power for cheap is a good ol' LS swap.

The guys see if the Nascarlo or the Death Metal Charger is faster around a dirt oval. After Finnegan wrecks the Nascarlo, the guys improve the nose, but also add speed to the Charger, setting up an epic "goin' left" battle.

John Andrade Jr. from Street Outlaws joins the guys in a messy battle, when a '75 dirt-track Camaro goes head-to-head with a big-block-powered Toyota mud truck on a makeshift drag strip down the center of a mud park.
