Whatâ€™s cooler than building your own jet engine? If you said nothing, youâ€™d be correct. The guys at Bad Brothers Racing and Garyâ€™s Jet Journal have teamed up to bring you instructions for building one of the most bad-ass ways of powering any vehicle: a jet engine. Using an automotive turbo, a homemade combustion chamber, and a little down home ingenuity, you too can burn down the highway on your own jet-powered vehicle of choice. I for one would love to see a jet-powered skateboard, though itâ€™s partly because Iâ€™m sure it would make for some great video of a guy falling flat on his face at greater than highway speeds (though I would want it to be one of those â€œand he walked away unharmedâ€ type videos, otherwise Iâ€™d just feel bad for they guy, taking one for the team like that and all).
