PERFORMER RPM II CARB/PLATE NITROUS SYSTEMS
(SINGLE-STAGE: 200-400+ HP)
Dyno tests on a 500-inch Chevy proved that even at 400 HP 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. Plate System has more tuning capabilities than any plate system currently available. 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. Kits include everything shown to the right including a 10-lb. nitrous bottle (shipped empty), stainless steel jet selection, hardware and owner's manual for a complete installation. Add billet aluminum Solenoid Brackets #72286 or #72287 for an even more professional looking installation.
