I have Nitrous on my 2000 Dakota R/T. From the show room I went 15.6 in the 1/4 mile to a best of 13.32 in the 1/4 using a 80 HP jet in the system and a pair of slicks. Cheap Horse Power, but you just have to be carefull not to over do it. Start at your lowest jet in your kit and make some passes. Check your spark plugs regularly (to see if you are leaning out) up your jet size if you and your vehicle are happy.
