Frank N20 when released from a tank in liquid state allows us to burn more fuel into the motor(systems use gas/propane as extra fuel).Its the cheapest HP/$$$ you can get.Average Nos system on a viper will safely give 125rwhp.On my system hp jet changes can be done in 5min at you fingertips.You may want to run around the slippery streets with 100rwhp,then show off at the track with 10-11sec passes with 130+mph with 125-135rwhp jetting.There are some bada bing bada boom chances you take(such is life).Thats why you have something special with the viper(Race car with a warrenty).I like the "Juice,spray,sneeze"because its there in a few seconds anytime you need it,saving your stock motor's internal parts from high cycl.presure,excessive wear on parts, all the time.Installed correctly can keep your engine,plugs cleaner!With a cool through the hood purge set up,most of the dissrespectfull punks give you the thumbs up without a challenge!
