i ws think about getting a purge kit for my car ive already got the nitrous hookup and everything. how much are they going for and what purpose do they serve besides looks do they help u out in the 1/4 or what

 

Well.....a purge kit is kinda useless, although I have one. All a purge does is to get the air out of main feed line. Let's say you haven't sprayed your car in a couple days and you go and open your bottle. Well when you go to purge it, you'll hear air come our for a second or so, then nitrous. It's really good for a wet kit so you're not spraying air/fuel instead of nitrous/fuel. Causing you to load up on gas possibly resulting in a really rich mixture or puddling of the fuel in the intake...which is NOT good.

With a dry kit, you can easily purge during your burnout. If you have a WOT switch, which I'm sure you do, just go WOT a couple times in your burnout with the nitrous on and you'll clear the air while doing the burnout. Of course, if you have a wet kit, the purge is a good item to get, as I explained above.
