LeMons competitors Freerange Racing's unveiled their "perfected" wind-powered supercharger. Made from HVAC ducting blades connected to a flex plate, geared to a starter shaft and turning a 14L semi turbo. Pushes 1PSI of boost at 65MPH and looks delightfully dangerous.

Though the likelihood of this contraption making it through tech inspection at the upcoming Thunderhill race is infinitesimally small, you have to admire the ingenious dumbulence of this thing. It's hard to imagine razor sharp spinning blades leading to anything good when mounted to a $500 race car. It probably creates more drag than it overcomes with power, and it's a clattering madness-maker but wow, talk about cool. [24 Hours Of Lemons Forums]
