Whipple Billet Throttle Body 109mm 1750CFM Mechanical (LSX Hot Rod / Sand Car) WTB-1750M-LSX
High-Flow Mechanical Throttle Body for Extreme LSX Builds
The Whipple Billet 109mm Mechanical Throttle Body is purpose-built for high-horsepower LS-based applications that demand maximum airflow and razor-sharp throttle response. Designed for LSX hot rod and sand car setups, this round-blade mechanical throttle body flows up to 1750 CFM, making it an ideal match for 2.9L, 3.4L, and 4.0L LSX builds.
CNC-machined from a solid block of billet aluminum, this throttle body features a knife-edged throttle blade and a straight-through bore to reduce restriction and maximize inlet efficiency. The result is increased airflow capacity with crisp, immediate throttle responseperfect for high-output naturally aspirated and boosted LS engines.
Engineered specifically for Whipple front and rear feed LS superchargers, this unit includes a custom extended throttle linkage arm designed to clear the supercharger housing. On modified engines, gains of 100+ horsepower are common when upgrading from restrictive OEM 90mm throttle bodies.
