Description
1250 CFM – 4500 – Mechanical Secondaries – Hard Core Gray – GasolineAll aluminum construction saves 3.8lbs. over original models (28% weight savings)Hard Core Gray with black anodized billet aluminum metering block and booster insertsDesigned for use on Drag race, Pro Street, or any high horsepower enginesCalibrations optimized for today’s larger race engines and new fuelsFully machined from venturii throat to throttle bore for predictable repeatable performanceIntegrated idle bypass valve allows for adjustment of idle while maintaining correct throttle plate to transfer slot relationship12 hole billet booster inserts for superior atomization and crisp throttle responseMetering blocks feature improved durability, true gasket sealing and fully adjustable (emulsion bleeds, power valve channel restrictors idle feed restrictors)Dual 50cc accelerator pumps provide the perfect amount of fuel from idle to full throttleFuel bowls provide 20% more fuel capacity while controlling slosh with internal bafflingClear sight windows on both sides of bowls for easy and safe fuel level adjustmentsBuilt in drain plug in front center of bowl provides easy access to empty contents of bowl-8 (o-ringed) inlet threads offer a large variety of plumbing options and can be plumbed from either sideFactory ready TPS mounting points for use with data acquisition systems (Holley TPS P/N 534-214 available)Knurled (hand adjustable) primary and secondary curb idle screws allow for easy idle adjustment without the use of toolsContoured hex head squirter screws for streamlined airflow100% wet-flow tested by Holley technicians to assure it arrives ready to run!Fully adjustable stainless steel external linkage can be adjusted for 1:1 progressive, or soft progressive throttle activation. No linkage parts under the carburetorThe original Dominator® took carburetion to another level in 1969 when it was developed for NASCAR® racing. It has been refined over the years and has received its biggest change ever. The Gen 3 Ultra Dominator features a brand new mainâ??body, brand new stateâ??ofâ??theâ??art calibrations, high volume fuel bowls and sizes up to 1475 CFM!The patent pending GEN 3 mainâ??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.The main-body also features an integrated idle bypass valvethat allows for idle adjustments while maintaining the correct throttle plate to transfer slot relationship as well as an extended air cleaner flange for easy air scoop attachment when using the available air scoop adapter.The Gen 3 utilizes high capacity fuel bowls which feature 20% more fuel capacity to eliminate starvation, integrated fuel shelf to minimize fuel aeration and internal baffling to control fuel slosh. Other features include all aluminum construction, 12 hole billet booster inserts, fully tunable billet metering blocks, adjustable external linkage, throttle position sensor mounting points andknurled (hand adjustable) curb idle screwsEach calibration has been dyno and track tested to deliver proven performance!
