  • Horsepower Reduction Carburetor Spacer

    This 1.000” thick 4-hole spacer is designed to reduce horsepower when the racetrack gets dry slick and high horsepower becomes a problem. The 4-holes are machined to match up with the base plate on one side and then taper down to .875” on the intake manifold side. The .875” portion of the spacer can be machined to reduce the horsepower, as you desire. We also offer them machined to special sizes as well.

    Many racers select 2 to 3 different sizes and select the one best suited for the track condition. The horsepower can be varied from 50 to 200 horsepower depending on the size of the hole.

    The spacer can be used for classes that require a restrictor plate. You can purchase a spacer the size of your restrictor plate and greatly increase the power by smoothing out the fuel entry into the restrictor plate.
