AVS2 500 CFM Carburetor # , Electric Choke, Chrome Plasma Finish (Non-EGR
Description
Edelbrock's AVS2 #1901-CP with Electric Choke is a special Chrome Plasma finished 500 CFM street carb with annular flow booster technology for near-EFI-like drivability that you can feel as soon as you step on the gas. The AVS2 1901-CP features an annular ring with eight evenly spaced orifices replacing the standard single brass tube (down-leg) fuel feed. The AVS2 booster ring distributes fuel into the airflow stream with an even spray to eliminate flat spots and greatly improves throttle response in the low-to mid-RPM range without sacrificing top-end power. The Chrome Plasma finish is applied is a 7-stage process to ensure the most durable and brilliant finish possible.
The durable AVS2 is unaffected by engine backfires since there are no power valves to blow out. For fast and simple part-throttle tuning, metering rods and springs can be changed in seconds without carburetor removal or fuel draining. AVS2 carbs have the unique ability to hold a tune when compared to other carburetors. Your tuning and adjustments stay unchanged, so performance remains consistent. Updated primary and secondary booster clusters in the AVS2 offer the most accurate and up-to-date calibration available for today's fuels and octane levels. Additionally, the unique Qwik-Tune secondary air valve allows for limitless calibration of the secondary circuit. Adjustments can be made with simple hand tools in seconds to suit your application.
AVS2 Carburetors feature a two-piece design for easy tuning that allows you to make float level adjustments or replace internal components without draining the carburetor or removing it from the engine. The 1901-CP AVS2 500 CFM is manufactured by Edelbrock in the USA.

When you design and sell the best-engineered performance products in the world, you have to have a rigorous testing program. Why? Without adequate testing, there's no way to stand behind your product with confidence. That's why every product we design and sell at Edelbrock is tested and approved by Edelbrock engineers in a real world environment on state-of-the-art equipment. Our three Super Flow computerized engine dynos are capable of measuring 11 separate engine variables up to speeds of 12,000 rpm. For 2007, we added a new Super Flow SF902 engine dyno. It's fully automated and programmable to simulate various driving situations, and is equipped with WinDyn software for the very latest in testing equipment. For real-world tuning, there's our Super Flow model SF-840 eddy-current chassis dyno that can handle up to 1,000 hp at the wheels and speeds of 200 mph. When all testing is completed, the results evaluated, and the part has passed all performance criteria, then, and only then, is the product deemed ready for production. These precise testing procedures are applied to the entire Edelbrock line for performance that's guaranteed. Edelbrock test vehicles are driven by Edelbrock engineers and employees to get a "real world" feeling for the performance improvements. Our products are also tested and used by professional race car teams and drivers. Working with these talented individuals is just another extension of our research and development process so when we say "proven performance" we really mean it! Top racing teams in all forms of motorsports rely on Edelbrock to produce parts that they can count on to win races and championships. Further underscoring our commitment to the racing community, Edelbrock is the only aftermarket intake manifold manufacturer licensed by NASCAR.
