New! Hasselgren’s first billet barrel throttle valve
Barrel throttles have an inherent advantage over butterfly throttles in regards to flow and power. This package has been designed for stock port injection or “trumpet” injection.
In “trumpet” or “gantry” style injection systems (where the injector is mounted upstream of the velocity stack) the barrel throttle typically has issues with part throttle fuel droplet handling. Hasselgren’s internal design details addresses these shortcomings.
Note: as a retrofit to a Swift 014 chassis, the trunnion bar also needs to be replaced.
