Just when I thought the mods would stop..... Just when I thought I could give my bank account time to recover.... I have been looking up on the internet about water / meth injection and have a couple of questions. Do you only use it on track days? Can you switch it on/off at any time or does it constantly run? Is it good / better for the engine? How long would a 1 gallon or 5 gallon tank last? Is it expensive to keep filling up with methanol? Sorry for all the questions, its just something I have no idea about. I am just curious if you could use it like NOS, flick a switch and have extra power! Thanks for any answers in advance!
