But here's the catch: they won't be able to see a thing! Each team will have three attempts to feel their way blindfolded to victory. Whoever makes it the furthest, or completes it quickest, will win. During the race, nobody was able to get exactly to the goal, but Red team won by finishing the race with team's own vehicle being closest to the goal. Team members Rich, the Californian godfather of custom cars Kurt, a computer genius with a list of inventions as long as his beard Rosanna, a hot-tempered junk artist from San Francisco Johnny, a tough-as-nails New Yorker and master fabricator Mike, a machine-minded cop who has his own problems with authority Sig, a theatrical set builder who loves tools but hates taking the back seat

S11 E7 • Sky Snipers

Both teams have only ten hours to build mobile weapon systems that can shoot down weather balloons which are floating thirty feet above the ground.

S11 E8 • Junkyard Mega-Wars: Speedway Showdown

Racing team members from NASCAR, Indy Racing League, and NHRA leagues spent 10 hours to build race cars that can run fast in staight line, a chicane road course, and an oval track. First course is a 1/8-mile-long drag strip, second course is a 5-lap road course, third course is run in 1/3-mile oval circuit for 10 laps. The combined scores in first two course will decide the pole positions of the drivers in third race, with the highest scored car at first. The triple track winner would be the one that finish first in the final round.
