Running a 100% meth... No big difference from running race gas or E85 with a really good IC IMO. To say there was no corrosion doesn’t mean there wasn’t. Its fact methanol is corrosive to Aluminum, no way around it.

See though, with direct port injection it’s very very hard to see atomization; there is just not enough space. Even with high pump pressure it’s still going to pool up, which makes for great cylinder cooling but not very effective charge cooling. So at that point the benefit is no different than race gas. Cooling the charged air is very important.

Another fact with H20 when you inject it you have to take out the extra fuel that is used for the cooling of the motor. When you do this you remove CO which was created by the excess fuel. CO which is bad air, when it’s removed it is replaced with good air which is then burned allowing for more power.

I promise you could make the same power and Tq with little to no corrosion out of a 50/50 mixture with just 2 jets properly placed. Direct port will see the best gains out of 100% water. Just like the rally teams do. Whats the point of doing something if your not getting the absolute best gains out of it?

The other factor, you’re in a cold climate, I’m in a hot and dry climate, and waters benefit to me here is much higher than yours. Being that as it is, meth should be a better option for you than me. Water is better for me as I can get H20 to fully evaporate in the heat here.

So many factors, what’s best for you, your car, your tuning, your boost, your jets, your mixtures, may not be best for me. That is why Aquamist and a majority of your injection companies say 50/50 mix with at least 1-2 jets for everyone.
