hmm... catch the water from the AC, suck it up (through vacuum) to the main water tank and you'll only need to add ethanol + water in winter. if you have the main tank air tight, it'll suck the water from the AC right in as you're using the water injection.

I have a water injection kit from the 70s!
I am really surprised that the EPA hasn't mandated it. I mean, they mandated the asinine pee tank systems which have ridiculous cost.
My guess is they haven't figured out a way to make water injection super expensive and a major inconvenience.

True WW2 planes had water injection , also the B52 and KC135 had water injected engines , thousands of gallons were sprayed into the engines to produce more thrust on takeoff but it made them smoke badly and it made them extremely loud.

Back in the day they mixed washer AF in with it, or used it straight up. I wonder what impact if any that would have though.

The biggest problem is that if the system goes awry, you have either a hydro-locked engine the next day, or corrosion issues in the upper cylinder ... As long as the system is functioning, no problem. One drippy water injector and you have big problems ...

Learn something new every day. I saw one of those aluminum 215 blocks at a junkyard once, but never knew they could be had with a turbo.

Back in the day, I was (for want of a better word) technical advisor on a low buck Hillman Hunter Hill Climb sports sedan, big turbo, big boost, single 1-3/4" S.U. carb 1725cc 4 potter.
We came up with a boost sensitive water injection system by porting boost to a pressurised tank, which then fed water into the turbo intake through a basketball needle...worked great...high speed enrichment, pull the choke on, and the SU carb would drop the jet that the needle sat in and get the lambda back somewhere reasonable.
(the guy later adapted a Haltech to it himself, which I was pretty impressed with)
Water has a surprising effect on power in many cases. Tolerance level varies per platform, but I have seen real world increases. Small, but with the added bennies of cleanliness and low egts it's easy to like if you are a serious enthusiast...

Hahaha, give them a little time, they'll surely muck it up...

Along these lines, people have experimented with 6 cycle engines. The extra cycles were for injecting water and not gas. The water would turn to steam in the combustion chamber and rapidly expand, pushing the piston down. It produced more power, and used less fuel.
It is a way to reduce some of the energy loss to heat. Not sure why it is not being developed by major players... maybe impractical/too expensive for the gains?

Can't figure out how to modify my posts if I come back at another time. Is there a way?
Here is what I was going to try to edit in: https://en.wikipedia.org/wiki/Six-stroke_engine

Vari-Jection was the product name; I had a 430 Buick I installed it on; GREAT product.

The water wasn't for thrust. The water was for cooling. And it the smoke was from rich combustion, not from water. They were loud (with or without water) just like every other turbojet of the era.
