When describing the obvious performance benefits from using nitrous oxide, substantial horsepower increases (from 50 to 350) are possible on your average small- or big-block Chevrolet, Ford, or Mopar V-8 engine, when equipped with a single-stage street/strip N₂O kit using a standard-flange Holley, Ford Motorcraft, or Autolite single 4-barrel carburetor; a dominator-flange-design Holley; or a spread-bore-design Carter Thermo-Quad, Rochester, or Edelbrock single 4-barrel carburetor. However, no matter what type or brand of carburetor used, it is vitally important to the overall performance of the system that you start with a good one; adding nitrous only compounds existing problems. Sticking floats, lazy power valves, partially clogged jets, and/or fuel metering rods that are in poor condition can result in sloppy throttle response, backfires, or more costly and permanent engine damage.

Carburetor size also matters. A carburetor that is too large runs rich at idle and lean at wide open throttle (WOT). If in doubt, contact any of the leading N₂O kit manufacturers’ technical hot lines. They can assist you in selecting the right N₂O kit and recommend the right carburetor for the application.

Purchasing a factory blueprinted carburetor from either Holley Performance Products or Edelbrock Corporation not only provides peace of mind, it’s also a viable alternative to costly rebuilds. Ordering a ready-to-install carburetor from a specialty shop, such as The Carburetor Shop, Braswell Carburetion, or Quick Fuel Technology (just to name three) is another choice.
