The EVIL ENERGY 850 Carburetor is a high-performance 850 cfm carburetor built for serious power and racing applications. As a true racing carburetor, it delivers rapid throttle response and strong high-RPM pull, using a mechanical secondary design to open the secondaries instantly when you need full power. Dual fuel inlets keep this 850 cfm carb supplied under wide-open throttle, preventing fuel starvation during drag launches or sustained high-load racing conditions.
Constructed from 100% new, high-strength alloy materials, the EVIL ENERGY Carburetor ensures reliability and temperature stability on track, not refurbished or remanufactured components. Performance matches the Quick Fuel BR-67201 racing carburetor, but the EVIL ENERGY 850 Carburetor offers the same airflow and horsepower capability at a more affordable price point—making it the smarter, high-value choice for performance builders.
With universal square-bore compatibility, this 850 cfm carburetor installs cleanly on GM, Ford, and Chrysler V8 intake manifolds, making it ideal for drag racing setups, street/strip builds, high-compression engines, strokers, and track-ready muscle cars.

Who It’s For & Where It Performs Best
The EVIL ENERGY 850 Carburetor is built for racers, street-strip drivers, engine builders, and hot-rod enthusiasts who need fast throttle response and reliable high-RPM power. This 850 cfm carburetor is ideal for high-compression V8s, stroker builds, and aggressive camshaft setups where airflow demand is high. Whether you’re dialing in a weekend drag car, upgrading a track-day muscle car, or building a performance street machine, this racing carburetor provides consistent fueling and strong top-end pull.
On the road and track, the EVIL ENERGY 850 Carburetor shines in:
- Drag racing launches — instant secondary opening and full airflow.
- Highway pulls & roll acceleration — strong mid-to-top RPM power.
- Street-strip performance driving — crisp throttle and stable idle.
- Track days and test-n-tune nights — repeatable performance run after run.
For drivers wanting Quick Fuel BR-67201–level performance but at a more accessible price, the EVIL ENERGY 850 Carb delivers real racing results without the premium cost.

Why Choose the EVIL ENERGY 850 Carburetor?
1. Race-Level Performance at a Better Price
The EVIL ENERGY 850 Carburetor delivers the same airflow and race features found in premium 850 cfm carburetor models like the Brawler/Quick Fuel BR-67201—but at a significantly lower cost. You get full 850 CFM flow, mechanical secondaries, and dual fuel inlets without paying $800+.
2. Mechanical Secondaries = Instant Power
Unlike vacuum-secondary street carbs, this 850 cfm carb uses mechanical secondaries that open directly with throttle input—providing immediate acceleration and sharper response, ideal for drag racing, high-RPM pulls, and competitive performance driving.
3. 100% All-New Construction (Not Rebuilt)
The EVIL ENERGY Carburetor is built entirely new—no reused jets, shafts, or seals. This ensures long-term reliability and stable performance under race heat cycles, wide-open throttle, and rapid RPM transitions.
4. Pre-Calibrated for Track-Ready Performance
Tuned with #76 primary / #84 secondary jets, a 0.033-inch pump nozzle, and a 4.5HG power valve, this racing carburetor is ready to run strong right out of the box. Only fine-tuning is needed for aggressive custom builds.
5. Fits a Wide Range of Performance Builds
With a square-bore flange, the EVIL ENERGY 850 CFM 4-Barrel Carburetor installs cleanly on most GM, Ford, and Chrysler V8 racing intake manifolds—making it easy to upgrade street/strip cars, big-block builds, strokers, and drag setups.
