From the gas turbine engine in a wicked small car department comes the Jet Kart. This speedy runner sprang from the collective brain trust of Chy Wright and Henry Donald of sunny Yorkshire, England. Seems the fellas saw an advert for this small turbine, originally used to start the full-size engine on a F4 Phantom fighter jet, and thought putting one in a kart was a bang-up idea. The boys proceeded to cook a few turbines in testing before they mounted one of the 60,000 rpm turbine units into the kart and took it out to a runway for some SUPER JET-POWERED AMUSEMENT! The body is specially designed to create downforce and add stability, as the Jet Kart is not at all intended to be a flying car.
