For years, Pigpen, the junkyard rescued 1950 GMC truck from Roadkill, has sat dormant. Now the guys awaken a monster by donating the chassis of their own legendary 1985 S-15 in a body swap for the ages, then take on Randy Pobst at Atlanta Motor Speedway.

The guys convert their motorcycle-engine-powered '72 Honda Z600 coupe named Bozo into a micro sprint-inspired dirt-track ripper. Pro driver Taylor Reimer sets the bar in her 400-hp 1,000-plus-pound Toyota, but how close can Bozo get to her time?

The guys uncover a cop car racing series around the Ford Crown Victoria P71 Police Interceptor. With a handful of bolt-on upgrades, they turn their former police auction find into a road race ripper around Willow Springs. This much fun should be illegal.

The guys take on off-road Baja legend Cameron Steele on a brutal desert off-road course with a Baja Bug. They may be outmatched by Cameron's unlimited racing rig, but the addition of a 350 V-8 to their Bug closes a big gap.

The guys take their V-8-powered Pontiac Fiero–based Lamborghini Countach kit car known as the Scamborghini and give it a 6-foot lift. Why would you do that? To take on an insane wheelie-popping mud truck through what's known as a bounty hole, of course.
