Roseville, MI: PROFORM gives racers an economical way to quickly
optimize their air/fuel flow rates. Its new Trackside Carb Spacer Kit
(PN 67160C) combines a 1"-thick frame with a choice of three inserts:
open, standard four-hole and tapered four-hole. All components are made
of lightweight, heat-resistant phenolic material to minimize thermal
transfer between the carb and manifold, fighting vapor lock in the
process. The three inserts offer an easy way to tune the powerband. Four-hole models accelerate airflow to improve low-end torque. The open insert creates a high-rise manifold effect, increasing plenum volume and moving the throttle blades away from the roof of the manifold runners. This improves air/fuel distribution and flow, adding mid-range and top-end power. The PROFORM Trackside Carb Spacer Kit fits Holley 4150-style carburetors as well as PROFORM Race Series models.
