The original Dominator® took carburetion to another level in 1969 when it was developed for NASCAR® racing. It has been refined over the years and is now receiving its biggest change ever. Introducing the ALL NEW Gen 3 Ultra Dominator! The Gen 3 features a brand new main–body, brand new state–of–the–art calibrations, high volume HP fuel bowls and sizes up to 1475 CFM!

The new patent pending GEN 3 main–body is 5/16” taller than the previous generation! This new height allowed for larger radius air entries which were optimized using Computational Fluid Dynamics (CFD) software to deliver smoother flow into new fully machined, big bore venturii.

Each calibration has been dyno and track tested to deliver proven performance!

  • Internal baffling to help control fuel slosh and minimize float level fluctuations in hard launching or cornering situations
  • Fuel shelf below the needle and seat to greatly minimize fuel aeration and promote more consistent metering
  • Fuel trough designed into floor of bowl to route fuel flow directly to the jets and assist in keeping jets covered by fuel
  • Clear sight windows on both sides of bowls for easy and safe fuel level adjustments
  • Built in drain plug in front center of bowl provides easy access to empty contents of bowl
  • Contoured entry provides smooth fuel flow directly to needle & seat
  • -8(o-ringed) inlet threads offer a large variety of plumbing options (come standard with -8 o-ring to -6AN male adapter and -8 plug). Can be plumbed from either side
  • Material added in key areas (needle & seat area, fuel inlet, sight window area) for added strength in the demanding race environment
6061T6 BILLET ALUMINUM METERING BLOCKS
  • Improved durability, true gasket sealing (sealing surface integrity), bright dipped anodized for good looks and corrosion protection
  • Fully adjustable (emulsion bleeds, power valve channel restrictors & idle feed restrictors). Power valve channel restrictors now machined lower in metering block for improved fuel delivery to power valve circuit
  • Accelerator pump channel internally drilled eliminating need for external plug
  • Excess material removed for increased fuel capacity
  • New snap in place bowl vent whistle makes removal and/or replacement easier
