Well that makes sense. I'm still not well versed in engines but I am learning quickly. The only reason water surprised me is that I have pretty much been taught to NEVER put water into en engine but I do understand why it is ok now. Thanks for the answer to that.

Yeah, water in any other case is bad, except mixed 50/50 in the cooling system, lol. In this case it's sucked in in small amounts and flashes to steam in the cylinders, so it's not going to hydrolock the engine.

Exactly. A little bit of water goes a long way.

Back in the old school, non computered, low-quality fuel days it was common to see water injection units on engines (generally run as a water/alcohol mixture). It was used for anti-knock purposes and operated off of manifold vacuum. The reason it worked was that the cool water absorbed heat, reduced cylinder temperatures, and could even clean up emissions. This technology dates back to WWII radial aircraft engines, has been used in racing, and is still in use in huge diesel engines.

Some of our members have used Water/Methanol Injection on S/C engines, with varying results.
