APD Billet Enforcer 1250 Throttle Stop Alky Carb APD-2289
APD 4500 Series Billet Enforcer Drag Race Carburetors are one of drag racing’s newest and most popular carburetors. APD’s Billet Enforcer Drag Race 4500 Series Carburetors feature a custom CNC machined billet main body and custom CNC machined booster design for maximum air flow and strong booster signal. CNC machined billet metering blocks allow precise metering, a uniform fuel curve and superior adjustability with both 2 and 3 circuit systems available. 4 Corner idle systems offer consistent fuel control at idle. APD Billet Enforcer Drag Race Carburetors also feature adjustable air bleeds, non stick gaskets, large head idle mixture screws and come with a custom hard coating anodized finish. “These features along with our billet metering blocks, Teflon coated large window sight glass bowls, screw on jet extensions and a notched float makes this what I believe to be the best value the carburetor industry has seen.” These parts being CNC machined from a billet allows us to make whatever changes necessary without having to work around casting limitations. The billet also adds strength eliminating warped or broken main bodies. The fully CNC machined main body is hard anodized after machining to eliminate any corrosion problems and makes for a good looking carburetor for years to come. The throttle shaft bushings are made from an oil impregnated bronze to make for smooth throttle transition and eliminating throttle sticking off idle. The standard 7-9/16 x 5-3/8 hood scoop tray mounting flange is integrated into the carburetor which eliminates the need to run a plate below the carburetor making for a much cleaner setup. Externally adjustable linkage is Teflon coated along with 304 stainless steel hardware making it strong and corrosion free.
