New for 2022 is the 90mm HI-BOOST (HB series) of performance throttle bodies. Specifically developed for high boost applications, the new design provides improved performance and durability. 

We start with a sealed shaft that is pressure tested to 100 psi and stable under the high engine temperatures and high inlet air temps seen in competition and high-power street applications.

Next, we've redesigned the mounting coupler for the TPS sensor to eliminate erratic signals sometimes seen under high boost. Then the blade is installed in a split-shaft for superior strength – counter-sunk mounting screws hold the blade in a contoured design for improved airflow at full throttle. Initially offered in the popular 105mm opening, additional sizes will be coming soon.
