High Flow / High HP

Carburetor Spacers + Adapters Catalog Pages

Brzezinski - Manufacturers of the highest quality and largest number of special application phenolic resin   carburetor adapters and spacers available!  Specialize in  2bbl Holley® and 2bbl Rochester® carburetor applications.        

High Velocity Heads - Manufacturers of the outstanding "Super Sucker" and "Street Sweeper" lines of aluminum carburetor spacers. These are by no means your average carb spacer! Designed with air/fuel flow technologies versus ease of machining. Tested and used by top engine builders. Specialize in square bore (Holley®, Carter®, Edelbrock®, etc) 4bbl carburetors. Dyno tests show on average 10-30hp gains. We have a dyno test that even shows a 47hp gain! Click here.

CFM Technologies - We have been secretly making high horsepower carburetor spacers for years. We make these by hand porting our special air flow designs into Brzezinski phenolic resin adapters/spacers. Our ported adapters/spacers are now available to all those who want to make some serious horsepower. Compared to all 2 hole spacers and adapters, our 2bbl carburetor adapters/spacers  will make a minimum additional 15hp and a maximum 30hp+!

Engine Builders are Invited to Inquire.
We Want To Help You Make More Horsepower!!!
