Nitromethane works great for alcohol injection but does not mix well with gas. I have a case of 80% meth/20% nitro sitting in my spare room from my last car and I plan to use with alky injection when I get it for this car. You will typically see anywhere from 20 to 55whp increases with it. Your car will run leaner with it however so it is best to tune for it.

You can go to devils own injection forum to read up more on it. They sell a very expensive mix of it but I have it custom mixed for me at a fuel shop for $75/2 gallons.

Do not try to run it by pouring it in your gas tank, it will not mix well and if you get a puddle of it in your tank that gets 100% injected into your motor then bye bye motor. But then again you guys are mixing all kinds of crap in your gas that is not intended for automotive use so I guess you will learn the hard way lmao.
