New Technology for throttle bodies !!

The Only Four Barrel Drive-By-Wire Throttle Body in the racing industry.

1991 – We made the first in the speed industry billet 4-barrel Dominator 4500-series throttle body

2006 – We incorporated a dedicated high flow idle air control (I.A.C.) provision into the housing

2019  – Another first in the speed industry !!!  We packaged our Drive-By-Wire (DBW) system onto the totally re-designed throttle body.  The Version 2 throttle body has an increased throttle size, now 2.250″ .  Throttle shafts move effortlessly on Kinsler’s bearing style architecture with retainers which have internal lip seals.  The initial customer is an Off-road Trophy Truck Engine Builder, so this package is built for life in a very rough and dirty environment.

A control algorithm using three coefficients

This is a control loop feedback mechanism, providing a continuously modulated control

We use positioning feed-back provided by 6-wire TPS
