Holley GEN 3 Dominator

 Holley released their new generation 4500 series Dominator carburetor at SEMA last week, and it looks like they broke the mold for this one. 

Features include:   

-- 20% more fuel capacity vs. a traditional v-bowl eliminates fuel starvation and provides consistent air/fuel ratios

– 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 Pyrex 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
