Boost Your Formula Student Engine Performance with AT Power’s Shaftless Throttle Body
Experience superior airflow and performance with the AT Power Formula Student Throttle Body, engineered using our exclusive patented Shaftless throttle technology. Unlike conventional shafted throttle bodies, our design removes the central shaft, delivering a fully open, unrestricted cross-sectional area for significantly improved airflow characteristics.
Weighing just 331g, this lightweight throttle features a 28mm diameter Shaftless housing and our patented knife-edged butterfly valves (Blades). The result is enhanced induction airflow speed, improved throttle response, and increased overall engine performance, proven in competitive Formula Student environments worldwide.
