Well, reading through all the mumbo-jumbo:
"The efficiency is high (above 95%) because the gun-engine is cooled internally and the cooling preserves heat that is than converted into additional work."
If he had claimed 50%, or even 100% increase in efficiency, I could give him the benefit of doubt. But claiming over 95% right off the bat when a usual IC engine is around 20% - 30% efficient -- no way!

"The design of the gun-engine eliminated all causes of inefficiency in current engines inherited from the first prototypes of Otto and Diesel inventions. The myth that engines must be inefficient is exposed!" -- Stan (August 15, 2008)"
How did he eliminate friction and other (i.e. pumping) losses?

Water injection kits has been on sale as far as I can remember (at least 20 years) so there's not a whole lot new there. They actually work to some degree, but are rather finicky and capricious. However, because of his wild claims, my conclusion is that his engine is either a BS, or a scam.

Pratt and Whitney supplied water injected R-2800 engines to Douglas Aircraft for American Airlines' DC-6B order around 1950. The expanding steam inside the cylinders did provide a power boost for takeoff and acted as an anti-detonation agent. That was all good. However, the plane was still not able to fly from New York to Los Angeles non-stop with a full payload. Very little, if any, increase in fuel mileage was gained. It wasnt until the Curtiss-Wright R-3350 Turbo Compound engine on the DC-7 that non-stop coast-to-coast passenger service was possible. I wonder if the turbo compound system could be adapted to car or truck engines. It extracted waste exhaust heat like a turbocharger, but put that recovered power directly back to the crankshaft through a fluid coupling.

There's a WWII plane that uses the exhaust to keep the wings from iceing and they condence the exhaust. Separate the inert gasses and re-inject the water. Don't remember what model in was. I've ran leaner mixtures and had same power output
in non turbo engine useing water injection too help vaporize the fuel.

100 mpg carburetor

If you rerouted your exhaust into the carburetor you will eliminate emissions from unburnt fuel. It will not decrease the HP either. Grandpa saw one in the 60ís. Fuel companies bought the patent bc it works

I did some searching and came up with a few sites (all though I lost the sites.. but I do have some of the information I copied and pasted) about 4 months ago and came up with a few hits, but lately I've just been wondering why this information isn't let out.

Anybody have any light to shed on this?

I guess this one is doomed to repeat inspite of the information that shows it is almost completely unworkable. You will spend far more money and time trying to make this work than just going ahead and pulling up to the pump. The Pogue carburetor was the one we went to the seminar in Tampa Fl to hear about, as I said in my earlier post (much earlier). You have to stop and think of just how the carbs and F.I. work in such a wide range of conditions. As far as water injection goes, I did a lot of looking into it with a S.C. Supercoupe T-bird. If you want to see how it works, just read about what the Grand National buick guys did with it ! Information has it that just water alone on an engine with high compression (or for that matter any compression for which cheap gasoline pre-ignites) water allows timeing to be advanced up to where it should be in the first place, which does increase performance. By adding a mixture of alcohol it supposedly adds ~ 5% to that. Both are cheep, but then you need to buy some sort of water injection system. I think they are still being sold. In fact, I have an old (new, unused) edelbrock one on the shelf in my garage that I never found the roundtuits to install. T-bird gone and anything else high performance for that matter. None of the lawn mowers are that for sure !! BTW maxc P-38's and Mustangs had water injection.....P-38's were so bad because their 2 engines allowed them to pull out rapidly to either direction, apparently single props could only pull out very well in one direction because of engine torque. Sorry for the long.........but I am waiting on the roundtuits for that damn lawnmower!

As far as the "200" mpg carb, well, that's a nice objective but the Pogue carb and the carbs that Smokey Yunick built did everything they were designed to do......80 mpg.....Yunick's carbs on his rabbit and fiero...he initially got 50+mpg , doubled the hp/tq (IIRR they turned 13 sec 1/4 mile) and would meet epa emissions 5 years+ ahead of all proposed regs….they almost completely eliminated the coolant (down to 1 qt IIRR)...and on the initial got 50+ mpg.....80 mpg was obtained after further development.....
