The following vehicles are considered Emissions Controlled Vehicles:
Q1: How much horsepower does a 850 CFM carburetor support?
A1: A properly tuned 850 CFM 4 barrel carburetor can typically support up to 500+ horsepower, depending on your engine’s displacement, cam profile, and overall setup. The EVIL ENERGY 850 CFM carburetor is designed for high-performance builds that demand serious airflow.
Q2: What does 850 CFM mean on a carburetor?
A2: CFM stands for Cubic Feet per Minute—it measures the amount of air the carburetor can flow. A 780 CFM carb delivers 850 cubic feet of air per minute, ideal for mid to large displacement V8 engines that operate at higher RPMs.
Q3: Will a 4 barrel carburetor increase horsepower?
A3: Yes, upgrading to a 4 barrel carburetor—especially a performance unit like the EVIL ENERGY Carburetor—can significantly improve horsepower by increasing air-fuel delivery and throttle response, especially in high-revving engines.
Q4: What is the best 850 CFM carburetor for street and strip use?
A4: The EVIL ENERGY 850 CFM 4 barrel carburetor offers electric choke, mechanical secondaries, CNC-machined body, and dual fuel inlets, making it a top choice for enthusiasts seeking street drivability with race-ready power.
Q5: Can you put a 850 CFM carburetor on a stock 350 engine?
A5: Yes, but it depends on your engine build. A stock 350 small block may be over-carbureted with 850 CFM, but with headers, performance cam, and a high-flow intake, the EVIL ENERGY 850 CFM carb will shine.
Q6: How do I know if I need a 850 CFM carburetor?
A6: Use this formula: Engine CID × Max RPM ÷ 3456 = Required CFM. If the result is near 850, you're a great candidate. If you're unsure, the EVIL ENERGY team offers fitment advice for custom builds.
Q7: Is a vacuum or mechanical secondary better for performance?
A7: For aggressive builds or racing, mechanical secondaries—like those in the EVIL ENERGY 850 CFM carburetor—deliver instant throttle response and better wide-open performance.
Q8: Can I install the EVIL ENERGY carburetor myself?
A8: Yes! Our carburetors are designed for plug-and-play installation. Bolt it on, connect the linkage and fuel lines, and you're good to go—no tuning required in most setups.
Q9: Does the EVIL ENERGY 850 CFM carburetor fit Ford AOD transmissions?
A9: Absolutely. This carb is compatible with Ford AOD transmission linkages, making it a perfect fit for many Ford small-block applications.
Q10: What’s the difference between 600 CFM and 850 CFM carbs?
A10: A 600 CFM carburetor suits small to mid-size engines, while a 850 CFM carb is better for high-performance or large displacement engines that require greater airflow at higher RPMs.
