Whipple LSX 2.9L/3.0L/3.4L/4.0L Billet 109MM Mechanical Throttle Body W/ 1.75" TB Spacer - 1750CFM

This is a Whipple Throttle Body for the 2.9L, 3.0L, 3.4L & 4.0L LSX Hot Rod/Sand Car Supercharger Kits.

With the ever increasing demand for power, Whipple now offers the highest quality and highest flowing LS based 109mm round blade throttle body that fits perfectly with the Whipple W175ax front feed compressor along with some of the universal LS based systems. The billet unit that features a knife edged blade, straight bore and a whopping 1750cfm capacity!

The Whipple 109mm round throttle body is purpose built for the Whipple front feed and rear feed series LS based supercharger packages. With an extended throttle arm to clear the SC housing, the Whipple 109mm is an excellent upgrade and an easy HP gain on nearly all LS motors. Gains well over 100hp are extremely common on modified motors when replacing a stock 90mm TB.

Throttle bodies use the GM based TPS sensor (AC Delco 213912), a Whipple logo CNC machined on the top surface as well as the throttle blade. These throttle bodies are not intended as a direct bolt on, both require special tuning and some require machining. You will likely need to fabricate a throttle cable bracket. Whipple does not offer custom tuning for these units, consult your tuner.

Note: Includes 1.75" Spacer for 2.9L blowers to help clear belt, This Throttle Body has no provisions for IAC, uses remote IAC (See Picture 6)
