We've long admired the crew performing a Hayabusa engine transplant into a Mazda Miata, both for its technical complexity and sheer steel cojones. The latest lesson: When it comes to molding carbon fiber air horns, nothing beats a Trojan.

Dave Coleman's crew could have just gone with silicone air pipes, but rejected that solution as too compromising for the Miatabusa's 11,000-rpm breathing needs. Instead, the perfect answer came through some plaster, styrofoam and a piece of Ikea furniture. [MotoIQ]
