Billet 109mm Throttle Body (Mechanical) (1750cfm)

WHIPPLE BILLET 109MM THROTTLE BODY – MECHANICAL (1750 CFM)

With the ever-increasing demand for high horsepower builds, Whipple now offers the highest flowing, billet-machined 109mm round-blade mechanical throttle body—purpose-built for LS-based applications. Designed to complement the Whipple W175AX front feed supercharger as well as universal LS platforms, this CNC-machined unit delivers up to 1750 CFM of airflow for extreme performance applications.

Machined from a solid block of billet aluminum, this throttle body features a knife-edged blade and straight-through bore to maximize inlet efficiency. The result is crisp throttle response and significantly increased airflow capacity—ideal for high-output naturally aspirated and boosted LS engines.

DESIGNED FOR WHIPPLE FRONT & REAR FEED LS SUPERCHARGERS

This 109mm throttle body is engineered with a custom throttle linkage arm to clear the Whipple supercharger housing, making it a perfect upgrade for builders looking to squeeze more power out of their system. On modified engines, gains of over 100HP are common when replacing restrictive OEM 90mm throttle bodies.

KEY FEATURES:

• Massive 109mm bore for up to 1750 CFM airflow
• Precision CNC-machined billet aluminum construction
• Knife-edged throttle blade for improved flow
• Compatible with GM-based TPS sensor (AC Delco 213912)
• Whipple logo CNC-etched on both throttle blade and outer housing
• Extended throttle arm for SC housing clearance
• Optimized for use with Whipple W175AX and select universal LS supercharger systems

NOTE: This throttle body is not intended as a direct bolt-on. Custom tuning is required, and minor machining may be necessary depending on your application. Whipple does not offer tuning support for this component. Please consult your tuner prior to installation.

Finish: Natural machined billet aluminum

Fitment: LS-based engines using Whipple front or rear feed supercharger systems and select universal LS applications
