best throttle body?
U.M.I.'s 90mm throttle body was designed with state of the art 3D modeling software. Manufactured from A356 aircraft aluminum alloy and machined in house on the latest CNC machining centers. Featuring UMI's new parabolic throttle bore design virtually eliminates any "tip in" hesitation found in most big bore throttle bodies. Most billet straight bore throttles don't have this cut. UMI's throttle body uses the same bearings, seals, and shaft design as production throttles. This allows for a very durable design that can withstand the extreme temperature swings seen by street and racing applicaions without worrying about throttle sticking issues seen by other aftermarket throttle bodies. This throttle body is so good; it's being used exclusively by GM Racing for their racing efforts in Daytona Prototype, SCCA Road Racing, and Dakar Hummer Off-road racing.
