Velocity Carb Spacers

This spacer has been designed to form the bottom side of the carburetor. The design increases airflow and air fuel mixture quality by creating a pathway for the air fuel mixture to enter the manifold. These two qualities lead to increased horsepower throughout the entire rpm range of any motor (not just the "peak" power number). This greatly differs from that of an open or four hole spacer which create an abrupt transition from the carburetor to the manifold which slows the air fuel mixture down and allows atomized fuel to drop out of suspension and puddle (reducing low and midrange rpm performance).

CNC machined from 6061T-6 aluminum with this spacer look for:
  • Increased Horsepower (up to 20hp) Throughout the Entire RPM Range
  • Better Throttle Response
  • Increased CFM Flow through the Carburetor
  • Stronger Carburetor Signal

The Velocity Carb Spacer on a 750 Holley Carb

The velocity spacer was placed on a 347ci small block Ford. The spacer increased the the overall horse power by almost 40 and nearly doubled the vacumm. Check out the dyno pulls below!
