APD Billet Main Bodies
Instead of thinking outside the box we have thrown the box away with our new billet main body carburetors. Our new APD billet starts as a chunk of 6061 t-6 aluminum. This carb gets rid of the possibility of any bad castings or porosity issues seen in the past. This body is available with throttle plate sizes ranging from 2.000 all the way up to 2.650, while still retaining a standard bolt pattern. The combination of venturi shapes is endless. All of the machining is done here in house at APD on our CNC machining centers. These carburetors will have an additional circuit that will be very helpful on the throttle stop, and also aid us in feeding the fuel demands of the larger bores. This fourth circuit is also tune-able per venturi. This feature really aids the larger cubic inch single carbureted engines because it allows you to balance out all of the cylinders, especially when tuning with eight O2 sensors.
We have also incorporated the standard pattern for a dragster scoop tray right into the main body to eliminate the need for stands and spacers to get the hood scoop mounted on your dragster. Instead of the throttle shafts riding directly in the body, we have machined ours for graphite impregnated bronze bushings. These bushings will greatly smooth out throttle shaft operation and make sticky linkage a thing of the past. Like all of our new dominator carburetors, our billets will come standard with our adjustable external linkage. Even with all of these great features our billet main body will still utilize standard metering blocks and bowls, along with standard 3 circuit metering block gaskets. All main bodies will be anodized in the color of your choice.
Our in-house testing along with the testing of several other large, well known engine builders has shown our gas billet carburetors to be 25-40hp better than our cast bodied 1250. The alcohol versions that have been tested have shown gains ranging from 30-45hp over our most current alcohol 1250 carburetor.
APD Billet main bodies are in production now and will be available for $2398, with a 3-4 week lead time. Custom Black Widow spacers are available to match the larger bore billet carbs. For the ultimate Super Gas or Super Comp weapon, combine with our APD on-carb air stop for an additional $898 for the best .90 combination available.
