Description

1050 CFM – 4500 – Mechanical Secondaries – Hard Core Gray – GasolineAll aluminum construction saves 3.8lbs. over original models (28% weight savings)Gray anodized finish with black anodized billet aluminum metering block and booster insertsDesigned for use on Marine high horsepower enginesFully machined from venturi 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 bowl8 (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 airflowFully adjustable stainless steel external linkage can be adjusted for 1:1 progressive, or soft progressive throttle activation. No linkage parts under the carburetor100% wet-flow tested by Holley technicians to assure it arrives ready to run!J-Style Vent TubesThe 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 valve that 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 and knurled (hand adjustable) curb idle screws. Each calibration has been dyno tested to deliver proven performance!
