What is the effect of rain water on the zx14 as far as power produced ? at 100 mph would it be noticeable .? Let's remove all other things like traction , wind, etc, Could you induce water as a fine mist at the intake and would it have a tendency to cool the motor or simply take up space in hte fuel charge that was fuel, thereby lowering the power?

(Sheltering in Place is eventually going to get expensive.)

Hmmm I've heard of some race motors using water injection. But water molecules will displace fuel molecules so the overall mixture may be leaner. Probably need to adjust a bit.
P-51s used a methanol spray bar on the belly radiator to cool the motor when using full Military power

I dont think water in the air/fuel mix is a good idea.

Back in the early days of the 911 S, SCCA racers had a home brewed system to spray cold water from a cooler in to the fan and past the cylinder cooling fins. May claimed this worked to keep the intake cooler and had HP gains.

IDK

Used a plastic medical syringe with a 3/4 shot glass size body. Plastic line to a spray bar with fittings aimed down the v-stacks of the 14. Had the syringe glued to the side of the frame so I could take one hand and push the handle down into the syringe and feed water, then a mix of rubbing alcohol and water. Results? Don't bother.

Anywhere from letting it drip in with a steady hand, or a rush squirt, down to a high speed hard feed; which it more fell on its face being exactly what you said, chrly. Took up space. For what it's worth... Honda came out with the horizontal engine back in '75 was it? Some high milers came in with blown head gaskets. Being water cooled and slowly dripping into the cylinder chamber, [once the steel ring is burned away], then the paper burns until it really gushed out thru the water jacket hole, she'd steam clean the whole chamber/valves/piston as if new out of the box.

Elbow bump-bump, want those miles of carbon removed so 'more' gas/air replaces that buildup, nudge-nudge, wink-wink?

Just thought about this... say about Oct time and the dense air change occurs. I wish I had that setting all year round. We condense the air, we'd walk in a fog, right? So just that colder contraction of air temp is the mist to ratio you're looking for. Smoother, responsive like. Come winter time, crude and Mad might know that feeling I'm taking about... being on this side of the atmosphere-sphere.

Edit: To correct myself some. Minutes from posting, serendipity says besides gas law and all that, there is a certain mix of air/temp/pressure at that time of year is my guess. Hot is less air so lost performance. Moist as in rain induced is lost performance. Gas law says there is so much oxygen and nitrogen, but add H20, she goes lean. So that cold day is the best [ideal] tune if I think gas law vs seat of the pants.

Thanks guys. On my turbo 1200 I injected water into intake tube infront of the turbo..I know :) But I had put 25000 miles, yes 3 zeros, on the turbo and it was time to play with it ..The setup was held to 8 pounds ( Aerocharger).
Unfortunately, I did not quite get the install right and when boost came on the water shut off and yes teh water was spraying below boost.. I have a "test track" less than a mile from home. I rode there, and realized teh bike was not acting right. Took it back home and parked it thinking I would give myself a day or so to think thru the problem . Water build up that had accumalated in the turbo destroyed teh vanes and that was that ..This time , I am trying to put more thought into it before I do it again :)

On a side note.. the year was 1954 and My folks had a 1950 ford flathead . My cousin ( local hotrodder) installed a water injection on it.. always wondered what ever happened to it . I worked at my uncles gas station/ repair shop while in high school and I remember him slowly feeding water down a cab while motor running , to blast carbon build up.:)

Chrly, I ran water injection on one of my 1200 turbo Bandits.
I might be able to help out with some tips.
I also had a number of inter cooled turbo steet bikes.
Get in touch if you want to BS.

Would love to chat. PM your way.
