When every tenth of a second matters, serious racers turn to components that deliver consistent results, lap after lap. The JEGS Race-Series 750 CFM Gasoline Mechanical Secondary Carburetor is built with one purpose in mind: to unleash the full performance potential of your engine. Whether you're bracket racing at your local strip or fine-tuning your weekend warrior for the street, this race-proven carburetor offers the control, adjustability, and airflow your high-performance build demands.
Built for Power: What Makes the JEGS 750 CFM Race Carb Stand Out
At the heart of this carburetor is a high-flow design engineered for maximum throttle response. The streamlined main body eliminates the air horn and choke tower, removing airflow restrictions and allowing your engine to breathe freely. With wet-flow testing and a vibratory polished finish, it delivers both function and form under the hood.
The 4150 square bore design ensures compatibility with a wide range of intake manifolds, making it a drop-in upgrade for many high-output V8 engines. Designed for use with gasoline and with mechanical secondaries, the JEGS 750 CFM Race-Series Carburetor is all about putting power to the pavement.
Precision Tuning with Race-Bred Features
JEGS designed this carburetor to be highly tunable. It features hard anodized metering blocks with adjustable screw-in air bleeds, four-corner idle adjustment, and changeable idle feed restrictions. These components work together to provide ultra-precise fuel delivery no matter the RPM range.
The throttle baseplate includes power valve blow-out protection, slabbed throttle shafts, and slip-link secondary linkage for smooth, reliable operation. Whether you're launching off the line or holding steady at high speeds, this carb keeps up with the demands of racing.
Dual fuel inlets with included -6 AN adapters allow you to plumb the system from either side. A sight-glass-equipped fuel bowl with internal baffles ensures that fuel delivery stays consistent, even during aggressive acceleration.
Specs That Matter
Here are a few of the key technical specs that racers will appreciate:
- 750 CFM airflow capacity
- 30 cc accelerator pumps
- Mechanical secondaries
- Primary jets: 71 | Secondary jets: 82
- Primary discharge nozzles: .031 in.
- Power valve: 4.5 Hg
- 4-corner idle control

This carburetor is compatible with Innovate Motorsports TPS 39300 or a similar sensor if your build requires a throttle position reading for data logging.
Perfect for the Track or the Strip
JEGS Race-Series Carburetors are designed to work best in high-RPM, high-output environments, such as drag racing or competitive street/strip builds. The mechanical secondary design, combined with dual accelerator pumps, ensures an instant and aggressive throttle response. No delay, no hesitation, just raw, controllable power.
If you're looking for a race-ready carburetor that blends high-end features with JEGS-level value and support, this is the one to beat!
Easy to Service and Upgrade
One of the greatest advantages of the JEGS Race-Series Carb is its standardized components. It uses industry-standard jets, air bleeds, gaskets, and power valves, making it easy to service and customize. If you want to fine-tune fuel delivery for different tracks, weather conditions, or power adders, you can do so without tracking down rare or proprietary parts.
Final Thoughts
The JEGS 750 CFM Race-Series Mechanical Secondary Carburetor is more than just a bolt-on performance upgrade. It's a precision instrument that gives racers the tools they need to dial in their engine and stay competitive.
