HI-BOOST 105mm V-Band Throttle BodySKU: 471105VHB
New for 2020 is the HI-BOOST (HB series) of performance throttle bodies. Specifically developed for severe duty and 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.
Clamp is NOT included. Available as an add-on item above.
