Dedenbear Products PK1 Primary Butterfly Kit

Description

Primary Throttle Kit for Bear Stop TS1-modelsFits Standard Holley & Demon CarbsDedenbear's optional Primary Throttle Kit was designed for extremely fast cars and/or engines with huge displacements. In applications demanding E.T. reductions of five-tenths (.5 second) or more, this second set of Bear Stop butterflies and linkage is required. Bolt it on in 10 minutes! Unlike similar kits now on the market, Dedenbear's Primary Throttle Kit was developed on a flow bench to maintain an optimum air flow curve. The resulting design effectively adjusts the geometry between the primaries and secondaries throughout throttle travel, much like progressive carburetor linkage. The Primary Throttle Kit fine tunes the Bear Stop's effectiveness and response over the entire throttle range.
