Pretty much they are spraying the nitrous across the MAF sensor. Cold air temperature is read, the PCM then fattens up the fuel mix, which in theory gives you the additional fuel you need.

For our cars, spraying cold nitrous across a HEATED MAF sensor = premature death to the sensor. If you have ever had a problem with a failing or bad MAF you can understand how problematic it can be to determine thats whats wrong with your car.

For me and my old set up, I was injecting my nitrous after the throttle body, and before the supercharger. It could handle a 75 shot no problem what so ever.

My next new current set up is direct port, via a custom made nitrous spacer plate that sits UNDER the supercharger and sprays nitrous directly into each intake runner evenly.

Problem with spraying through the supercharger, and the ONLY problem is getting true even, port mixture/cylinder mixture. The way the out let of the supercharger is designed, and the direction of the rotors and how they spin, loads up one or two more cylinders with a much greater hit of nitrous than the others.

Nitrous does not have any effects on the rotor coating, wet or dry system. The coating only peals off, if the rotors were coated incorrectly from Eaton to begin with. Same thing with running alcohol injection, no effect on rotor coating being harmed.
