methanol injection

has anyone tried methanol injection on their race car and how did it work. this would be on a carb engine.

Are you talking about straight Methanol or Meth/H20 (washer fluid)? I run a Snow Performance water/meth system. I mainly installed it because I'm at about 11.2:1 and I didn't want to drop $8/gallon on race gas when I'm at the track. It works well on the street too. Snow claims big HP gains w/ the system, I'm guess because you can run as much advance as you'd like. Here's a chart on a 426 Hemi. Here's a link to my set-up. https://www.youtube.com/watch?v=JYw2q7igDGs

I've considered this as a alternative to intercooling. I am planning on going with air to water intercooler over my air to air but if this would work as good as an air to water it sure would save weight.

Assuming you mean switching entirely over - it's a great option for a race car as long as you are willing to handle the fuel system maintenance. I switched to gas in between races and had ZERO problems. Of course I was running EFI so I was able to keep it lean enough at idle to not milk the oil. Mechanical system usually run richer at idle. Engine ran much cooler too.
