Nitrous Systems are dyno-tested and calibrated to deliver accurate and safe horsepower gains. Nitrous kit calibrations are determined through dyno-testing, not simple mathematical formulas, which do not take into account real-world variables. Available from 50 to 500 horsepower, Nitrous Oxide Systems and components are the quickest and easiest way to get large horsepower increases with a minimum of engine modifications and expense. It’s serious horsepower available at the flip of a switch.
