This is the only site on the internet that considers meth spray aka nos aka nitrous lol.

It is a cooling mod, plain and simple. Try it on a N/A engine and see if you make power lmao.

It raises the octane of the fuel and cools temps drastically. All the information regarding alcohol injection you could ever want is just a google away.

Also as for nitrous, anyone that thinks it is cheating is ignorant. It is no more cheating than drag radials, weight reduction, turbos, superchargers and so on. It is just another power mod. Some people just like to complain about what they are afraid of or no nothing about and they are typically the ones that never break records.

I am sure a lot of misinformation will fill up this thread but if you really want to know about it then do a google search and read to your hearts content. That is the best advice I can give you, not to listen to people that have never used it or know little to nothing about it or heard from a friend that had a sister that knew a guy that once had a uncle that used it once he thought.
