Dude I was wondering the same damn thing. The only thing that scares the crap out of me is Nitrous backfire. It's like someone took a Wenchester 12guage with 4" slugs and took a straight shot through my block. Please be careful when you/ if you use NOS. If your timing goes bad, so does the nitrous. LOL Reminds me of a guy I raced at the track awhile back, he was backfiring from the lights to the finish line.
I like the wot switch along w/ a window switch. Eliminates the chance of a backfire. If it's your first time w/ nitrous. Probably just start w/ a dry kit usually 75-125 hp. Wet kits usually cause the manifold explosions. Zex makes an easy wet kit, but never seen it used in person.
GET A ZEX DRY KIT !! it's idiot proof, has a nitrous management unit that compensates for bottle pressure and is super easy to install, you don't have to rig up a microswitch either, all you have to do is run a switch inside the interior and then tap into your throttle position switch, you don't need to tap into the fuel system either, the instructions are excellent , you will not be disappointed !!!!!!!
i've used lots of nitrous kits, nitrous works, big shot, nozzle types and the zex dry is my favorite, btw if you are a decent driver and can stay off the rev limiter you won't need a window switch
I am running a Zex 75 dry shot. It was super easy to install and now all I do is open the bottle and flip the switch. I have been just practicing around with it. It is Awesome. I cant wait to make my first pass in 2 weeks at the track.
