I am looking at purchasing a complete wet NOS kit that is the Nitrous Express with a 150 shot. It comes with all the sylenoids, cables, 15lb bottle, arming switches, bottle heater, and guage for the bottle. My questions to everyone is this, is NOS worth the money and if so which system is better wet or dry? How do you tell which sytem it is? Sorry is I sound dumb I just have never used it before. I can get the setup for $250 and the guy is a mechanic and will install it for free. Please leave me some suggestions. Thanks to all your help.

seems like a deal. I would do some reasearch on google and see what others say especially in those ricer forums. they tend to use nos more often than really building an engine. Seems like a deal. Wet kits usually go for a grand or so?

Wet kit introduces an extra shot of fuell with the nitrous oxide. Dry kit is just nitrous oxide. I recomend going with the wet kit so the engine doesn't run too lean. Also you will have to modify your timing. For ever 10 Hp added retard the timing 10 degrees, but you should get a timing box so it kicks in and retards the timing ONLY when you hit that little button. Also look to invest in an intake manifold and camshaft designed especailly for NOS.

ok.....quit telling people 10 deg for every 10 hp;) thats wrong.....to be x-tra safe on your system some people follow the 2 degrees of retard for every 50hp rule
but as long as you have a good fuel and spark system and are running good gas 110 or higher you can get away with 1 degree of retard for every 50hp.
make sure you are also running a plug anywhere from 1 step to 3 steps colder than stock...depending on how much your throwing at it.

how do I retard my timing only sometimes please explain thanks

I aint no expert but I would refer you to the Tuning with nitrous post I know DAZ28 is very knowledgable about the systems as are others on that post.

You can prolly use a dry kit on a fuel injected for a 125-150 shot, the stock fuel injectors should flow enough to handle that, the nitrous kit ya buy should have directions with some of the limitations in it. Ya would have to get injectors that flow more for larger shots or go to a wet kit. You can search the Corvette forum too, alot of guys run dry systems an blowers on they're C5. http://forums.corvetteforum.com/zeroforum?id=86
