Prime example of why I dislike Nitrous. If you ask me, it's a pretty dangerous way to get that extra power you want. It's too damaging to engines (as you can see) even if you do know how to use it properly. I'll never think about N2O as a performance mod, and that is why.
Why do you need nitrous in a car that can already kick everyone's ass? If you have a car like that, I'm sure you can afford upgrading engine internals to get the same performance boost as Nitrous provides. Idiots....
