wet shot meant that your nitrous line is spliced in with your fuel line, thus when the nitrous is injected, it has a small amount of gasoline mixed with it...it helps to prevent from extreme leaning conditions which are naturally caused by using a nos mixture....dry shot is simply the nitrous gas, injected alone....
dry shot kits are much easier to install, due to the lack of having to splice into your fuel line...also with a wet shot system, in the case of a V6....you have to fuel rails to deal with...but the wet shot kit is MUCH safer...if there is such a thing as a safe nitrous kit...i have driven/raced a bottled car..and it is quite a bit of fun...until it blows up...[&o]
i mean..for instance...we bolted a wet kit 55 shot onto a car, and it was a bit of a pain to install it...but it went from running 16.50s to 15.40s...on an engine with 160k on it...and it ran for a whole race season...spraying on the street and track...but 55 isnt a very heavy shot...
on the stock motor in my car, we ran a 50 shot dry, and went from a 17.2 to a 15.4. but after awhile, N2O gets old, and youre gonna want a turbo or SC.

the wet mixes the nitrous with fuel and is allot safer to use b/c of the extra fuel. the dry is just nitrous. when used w/o any richining and a high shot (100) then ur asking for trouble
