JNJ fuel systems is the source for high performance carburetion. We're your source for custom built carburetion, race track proven racing parts.
Each JNJ carburetor has been individually modified based on critical, confidential information provided by the customer. We'll ask you to provide engine and fuel-delivery system specs and tell us about the operating conditions your vehicle faces in its typical racing environment. That way we can customize your carburetor to help your engine make competitive power in the broadest possible RPM range.
We can wet-flow carburetors measuring airflow, fuel flow, manifold vacuum, and air/fuel ratio throughout the entire RPM range. This enables us to properly match and balance fuel delivery on all throttle bores and control the metering signal and strength at all engine speeds
When completed, the carburetors are tuned and tested on an in-house engine attached to a Superflow SF-901 dyno featuring the latest version of WinDyn software. This monitors the various aspects of an engine’s operation, such as horsepower, torque, and O2 sensors for real-time air-fuel ratio.
JNJ manufactures a complete line of Quality Fuel System Components carburetor kits, billet spacers, CNC billet metering blocks & billet baseplates, replacement parts, gaskets, linkages, braided and stainless line kits.
JNJ Fuel Systems' goal is to make each customer's racing effort more successful. Let us put our knowledge to work for you!
