Absolutely lovely! Now *that* is a real car, with real gauges, no electric crap, no "technology" and no touchscreen. The way the Gods intended cars to be!
It works! Revving the nuts off a TJ ended up giving it way more power (no more carbon buildup)

I love running distilled water in my engine every once in a while. Does no harm and helps it! On old engines you can see where a head gasket is leaking when you pull the head off and the leak is right next to a sparkling clean piston 
Also, running your Jeep around 3,000 rpm is great for it. Peak efficiency

I had 2 Spitfires many years ago never could afford a TR4 or TR6 although I wished I kept my GT6 coup
as stated earlier, doing this going uphill is a must. it doesn't work going downhill , it doesn't let the carbon roll out !X 2, still an issue even with unleaded.
My favorite method is driving HARD up a mountain pass like Rabbit Ears or Eisenhower flat out in 3rd for minutes.
Keep the revs up, world of outlaws style
Believe the folks on here this works.
i always remove my plugs and fill the cylinders with dawn and water. man it removes the grease and oil and gets those pistons squeeky clean, adds atleast 30 h.p.to my 2.5 according to the butt dyno....I love running distilled water in my engine every once in a while.

This used to be used in aviation to cool the air and add power for short durations. I believe it was used in conjunction with leaning out the mixture (which runs hot).
They used it for long duration flights during WWII too. It helped Allied bombers with heavy bomb loads reach and maintain their high cruising altitudes. They still use it in some aircraft, and even for some jet engines. Mechanics love working on engines with water injection, they're squeaky clean inside.
You can always tell the water injection acft like the A model KC-135...they used to leave a plume of smoke behind them on takeoff. I remember seeing them when I first enlisted thinking they must be on fire.
I did the Italian tune up on the highway a few days ago and got a scary raspy noise from my engine bay I believe.
Dropped the rpms and it instantly went away then I went back to 3500-3600 and it did it again. I could smell a tiny little bit of burning (no smoke). It’s possible that it was my 42rle transmission that needs replaced but I don’t believe it was.
Jeep’s driving fine since then. Maybe one of the newish idler pulleys weren’t happy with the higher rpms and 7up in the gas tank.

Y’all talking like 3500-4000 rpm’s is a special event……. I drive a SE. That is an average trip up the mountain.
Just be careful using this mixture and getting to 88MPH. The Flux Capacitor is pretty picky about the water you use in the tank.
But what if that carbon is in The combustion chamber raising the compression? Shit!!!!! I need to lug mine around a while.
