This guy, who’s cobbling together a single-seat, tube chassis racecar from scratch. A courageous act on its own, sure, but the real heroism is in the custom drivetrain. That’d be a turbocharged V12 hanging off the tail end—or, more specifically, two turbocharged Toyota Supra inline-six engines fused together. The builder is an ex-engineer, which explains the incredible fabrication work. Also why one cylinder head is ingeniously rotated 180 degrees to achieve a common exhaust side. Oh, and those manifolds. Hero.
