Nitrous Oxide - what is Dry or Wet set up? There is another...

What is a Dry set up or Wet set up and what are the advantages of each one? What are the disadvantages? Few days ago I exchange a turbocharger (Just the turbine) for a NOS system I'm try to figure how to connect all the system. I went to a friend's house to know how to connect it and this is what he told me. "This is very easy, just install the fogger in the air box before the mass sensor and use only the nitro solenoid. With this setting the car will compensate for gas automatically.” This is true; I can inject NOS only and let the car compensate for gas because the mass sensor will read the drop in temperature? Or this is a huge lie.

Dry kit sprays N20 through the MAF. The MAF detects the increased flow and the IAT sees that it's really cold. Fuel is then automatically added.

However you can't go a huge shot (i think 125 is the most that you can be safe with, and event hat you can have problems). If you max out the injectors you wont be able to add enough fuel and kaboom.

Wet kit is more plumbing but you have more control of how much fuel to add to the car. This setup sprays nitrous in after the MAF and the fuel solenoids add fuel

Yep...just as stated above. But just to make sure...what motor are you spraying this on. It is an LS1 based motor?
