Has anyone messed around with these new water/methane injection kits on their classic motors.I hear that they up octane from 93 to 110-115 which would allow some of the high compression motors to work well with the pump gas of today. From what I hear they can work fine with carbs,& doesn't take a rocket scientist to hook up.
Any one know about water/methane injection

I use Water/Meth injection on my supercharged Miata and the results are excellent. I am able to run high boost on stock timing without any detonation on 91 octane. Without the Water/Meth injection I was not able to run the car at the same boost/timing settings. Unfortunately, I don't have any experience with it on a classic or carb'd engine.
If your current engine setup requires high octane, I don't see why it would not work well for you. As you suspect, it is inexpensive and very easy to setup.
Ironically, Oldsmobile used it back in the early sixties on one of their turbo charged V8;

Is your motor built? I was thinking about running it on my NA motor (stroker windsor). I needed to trim my pistons a tad in order to keep it from getting to much comp to run 93 octane. I contacted AIS (good company and customer service). I wasn't convinced that the trade off was worth it. A little more compression running water injection, versus pump gas with a little less compression. As the water slows the burn rate (higher octane) and doesn't burn I don't think I'd really be coming out ahead on power. I had my pistons trimmed, and don't plan on running the water (but still might once the motor is done if still to much comp; been waiting way to long on the motor). From what I understand it is much more beneficial on a boosted or NOS application (can run much more spray/boost than without it and not worry about det).
I dont have my motor built yet, but was wondering how it would work.I was told that for a carb motor it has a bigger tank & good for 500-600 miles. It runs off rpm & can be adjusted. So i'm hunting advice & info, & anyone that has any please let me know. My thought is it is a cheap way to get octane,& could be mounted in trunk or some other out of the way place.thanks every one
for a carb none-power adder you can run just distilled water with an injection nozzle below the carb in a carb spacer (similar to NO2). This will raise the octane (which is just slowing the burn rate of the fuel) so you will be less likely to have detonation. Again, I don't think the trade off is worth it. You could theoretically bump the compression up some (more than where pump gas would detonate with a given engine, but not sure on how much more) and get away with 93 octane and water injection (instead of race gas). But I don't think you'll make any more usable power, so now you've added weight and complexity to your car for some additional compression. If your motor is not built I'd suggest having it built for pump gas, and then you don't have to worry about it. Still don't have my motor (but supposedly it is close). I told them to check the compression for me, if it is to high I might be forced to use water injection (or race gas). Not what I want to do, but I had already bought everything. One of the dangers of piecing a motor together rather than just doing it all at once. look at http://www.alcoholinjectionsystems.com/index.html; I contacted them and they were very helpful.
