What is Edelbrock AVS2 Carburetor?
The Edelbrock AVS2 Carburetor is a high-performance carburetor that's designed to deliver optimal power and performance to your vehicle's engine. Built with advanced engineering techniques and state-of-the-art materials, the AVS2 Carburetor is designed to provide superior throttle response and help increase horsepower and torque.
One of the key features of the Edelbrock AVS2 Carburetor is its annular flow booster. This booster design allows fuel to be more efficiently mixed with air, resulting in better fuel atomization and more even air/fuel ratios throughout the engine's power range. Additionally, the AVS2 Carburetor features a new calibration system that allows for fine-tuning and adjustment of the carburetor without changing its internal components. This makes it easy to adjust the carburetor for different applications and performance needs.
Another advantage of the Edelbrock AVS2 Carburetor is its durability. Constructed from high-quality materials and built to withstand the rigors of high-performance driving, the AVS2 Carburetor is built to last and deliver superior performance year after year. Whether you're racing or just looking to maximize the performance of your daily driver, the Edelbrock AVS2 Carburetor is a top-performing carburetor option that will not disappoint.
Frequently Asked Questions about edelbrock avs2 carburetor
Air-Valve Secondary
On the secondary side of things, this line of AVS and AVS2 carburetors gets its name from the spring-loaded door over the secondary venturi. Carter called this an Air-Valve Secondary (a slightly different “AVS” definition than Edelbrock).
AVS stands for air valve secondary, which describes the spring-loaded air-valve door. The Edelbrock carb uses a mechanical secondary but does not employ a secondary accelerator pump.
Basically, the AVS2 was designed to help your classic engine start quicker, run smoother, and allow for better low-end throttle response – all the benefits of EFI but without the electronics. When upgrading from a traditional down-leg booster carburetor, improved fuel economy is a definite positive!
The AVS is an acronym for Air Valve Secondary, which is Edelbrock's line of entry-level carburetors intended for mild street engines. This line already enjoys a great reputation among street rodders as a carburetor that you can bolt on and reap immediately success.
Edelbrock AVS2 650 cfm Square Bore 4BBL Carburetor 5.0 out of 5 stars. Read reviews for average rating value is 5.0 of 5.
Make sure your fuel pressure does not exceed 6.0 psi, optimum pressure is 5.5 psi.
Yes, to an extent. The carburetor regulates the air-fuel mixture by means of suction while an EFI system is able to deliver a much faster and accurate response through the use of injectors. EFI systems are able to run more efficiently and effectively which means fewer emissions and better fuel economy.
6.5 psi
Carburetor Fuel Pressure by Manufacturer
| Carburetor Style | Recommended Fuel Pressure |
|---|
| Holley | 5.5 - 7.5 psi |
| Edelbrock | 6.5 psi (max) |
| Demon | 5 - 6 psi (at idle) |
| Quadrajet (street engines) | 4 - 5 psi |
The entire engine is rebuilt. The guy building it says the stock 7.5 - 9.0 psi fuel pump will work fine with the Edelbrock AVS2 carb without a regulator. I've talked to a couple of Edelbrock techs and they insist that 4.5 - 5.5 psi is optimal, with no more than 6.5 psi.
Series carburetors. And is a traditional square bore carburetor. First of all the primary. Differences. Right are the butterfly sizes. And if you can see these two side by side the primaries.
Typical four-barrel carburetors are set up as either square-bore or spread-bore designs. The square-bore carbs have equally spaced and sized throttle bores while spread-bore carbs have two smaller primary bores and two larger secondary bores.
The fuel pump pressure should never exceed 6.5 p.s.i. Take the top of the carburetor off and check for debris in the needle & seat, also inspect the needle tip to be sure it's not compromised.
Fuel pressure to the carburetor will range from 4 psi to 7 psi, with some vehicles using higher pressure. Using the wrong fuel pump that delivers excess pressure can cause problems ranging from poor performance and lower gas mileage to flooding and carburetor damage.
Increased Reliability
EFI systems maintain optimum air/fuel ratios, eliminating random engine stoppages, oiled spark plugs and other problems associated with sub-optimal ratios. Carburetors tend to need frequent adjustments; EFI engines eliminate the need for repeated modifications.
Although fuel injection is by far the most effective and efficient form of fuel delivery, carburetors do offer their own set of benefits. Although fuel injection delivers more precise air-to-fuel ratios, it is significantly more costly and difficult to maintain than carburettors.
Make sure your fuel pressure does not exceed 6.0 psi, optimum pressure is 5.5 psi.
