Edelbrock Victor Jr. Single-Stage Nitrous Plate System #70056 is capable of 200-400+ horsepower. Dyno tests on a 500-inch Chevy proved that even at 400 horsepower settings, EGTs varied less than 5% from cylinder-to-cylinder. Features include shorter spray bars allowing more liquid nitrous to be injected into the intake for more even distribution across the plenum, a more balanced air/fuel ratio and a quicker response time. With four nitrous and four fuel jets, the Edelbrock Victor Jr. This efficient design, with a billet aluminum plate that’s only 11/16" thick, uses less nitrous than conventional plate systems at the same power levels. Precision EDM machined spray bars for the best flow characteristics available. Kits includes a 10-lb. nitrous bottle, stainless steel jet selection, hardware and owner’s manual for a complete installation. This system is for use with square-bore carburetors.
