Choosing the Right E85 Carburetor: Key Factors to Consider
1. Carburetor Size and Cubic Inch Displacement (CID)
Selecting the correct carburetor size is paramount for achieving optimal performance and drivability. Carburetors are rated by their venturi diameter, which dictates the volume of air they can flow. Oversizing a carburetor can lead to a lean condition at lower RPMs, poor fuel atomization, and bogging, while undersizing will starve the engine of air at higher RPMs, limiting top-end power. Engine displacement (CID) is the primary factor in determining the appropriate carburetor size.
Manufacturers provide sizing charts or recommendations based on CID and the intended use of the engine (e.g., street, strip, or a balance). For street-driven vehicles with moderate performance upgrades, a carburetor sized for the engine’s CID is usually ideal. For high-performance applications or engines designed for racing where maximum airflow is critical, you might consider a slightly larger carburetor, but always err on the side of caution to avoid the detrimental effects of oversizing. It’s often better to have a slightly smaller carburetor that’s perfectly tuned than an oversized one that struggles to deliver a consistent air-fuel mixture.
2. Fuel Metering and Jetting for Ethanol Content
Ethanol has a different air-fuel ratio (AFR) requirement than gasoline. E85 typically requires a richer AFR for optimal combustion and to prevent detonation. E85 carburetors are designed with larger fuel jets and different needle and seat assemblies to accommodate this richer AFR. Simply installing E85 in a gasoline-specific carburetor will lead to a dangerously lean condition, resulting in engine damage.
When selecting an E85 carburetor, pay close attention to its jetting specifications. Most E85 carburetors come pre-jetted for E85 or are easily tunable with E85-specific jetting kits. Look for carburetors that offer a wide range of jet sizes, allowing for fine-tuning of the fuel mixture across the entire RPM range. This adjustability is crucial for optimizing performance and ensuring the engine runs safely, especially if you plan to switch between fuels or run blends.
3. Construction Materials and Ethanol Resistance
Ethanol is a solvent and can degrade certain rubber and plastic components over time. This makes the choice of construction materials incredibly important for an E85 carburetor. Carburetors designed for E85 use materials that are resistant to ethanol’s corrosive properties. This includes specific types of brass, aluminum alloys, and specialized nitrile or Viton seals and gaskets.
When researching different E85 carburetors, investigate the materials used for the fuel bowl, floats, needle and seat, gaskets, and any O-rings. Reputable manufacturers will clearly state that their E85 carburetors are built with ethanol-resistant components. Avoiding carburetors with standard rubber or generic plastic parts is essential to prevent premature wear, leaks, and potential engine damage.

Researching user reviews and dyno results for specific carburetor models can also provide valuable insights into their real-world performance and ease of tuning.
5. Carburetor Type: Mechanical vs. Vacuum Secondaries
The type of secondary throttle operation – mechanical or vacuum – significantly impacts how the carburetor responds at higher RPMs. Mechanical secondaries open proportionally to the primary throttle opening, providing a more immediate and aggressive response. Vacuum secondaries, on the other hand, are controlled by engine vacuum and open more gradually as manifold vacuum drops, offering smoother acceleration and better drivability, especially in street applications.
For aggressive performance applications, drag racing, or engines with significant camshaft upgrades, mechanical secondaries often provide the edge in top-end power. For street cars, especially those with milder performance upgrades, vacuum secondaries can offer a more user-friendly and predictable driving experience. Some carburetors also offer a hybrid approach, combining elements of both. The best choice depends on your intended use and desired driving characteristics.
6. Mounting Flange and Intake Manifold Compatibility
Ensuring that the E85 carburetor you choose will physically fit your engine’s intake manifold is a critical step often overlooked. Carburetors come with different mounting flange patterns, the most common being the square bore and the spread bore. Your intake manifold will have a corresponding flange, and they must match for a proper seal.
Before purchasing, identify the bolt pattern on your existing intake manifold or the one you plan to use. Most performance aftermarket intake manifolds are designed to accept either square bore or spread bore carburetors, and many adapters are available if needed. It’s also important to consider the overall height of the carburetor, especially in vehicles with tight hood clearance. Some E85 carburetors might be taller than stock units due to their internal design for handling ethanol.
