This is NGM's 90MM Billet Tri-Flo throttle body designed for the Assassin big blower kit guys. The throttle body can be used in any application that uses the big ford bolt pattern. This throttle body is one of the most innovative designs on the market. It is the only 90MM throttle body that is completely plug-n-play for the Hyundai Tiburon 2.7L engine when used with our Assassin blower kit and 90MM inlet plenum. This unique design uses the factory TPS that is fully adjustable and factory idle air control. The throttle body has an innovative design that no one else employs on the market. We have designed the throttle body with three sizes in mind, 80,85 and 90MM. How did we do that? We have machined the throttle body to accept inserts in the throat of the throttle body to increase or decrease throat size depending on the insert used. We have found that the Assassin blower kit would draw almost 4 inches of vacuum at the plenum under a WOT dyno pull.This made the blower very unhappy. When testing with the 90MM throttle body, we picked up 30whp and elimintated the vacuum in the plenum making for a very happy blower.
