[@levifields5458]

this is probably the best example of one of these scale engines. it seems to have the lowest idle rpm and the best throttle response

[@blahorgaslisk7763]

Some years ago I stood watching an idling V12. Can't remember the car, though it was either a Ferrari or a Lamborghini. What stood out was the sound. It wasn't aggressive. It didn't gurgle and spit like most all performance built V8 I've heard. Instead it was like a well engineered and maintained sewing machine. It may sound silly but that was what it made me think about, and it impressed me a lot. Now a relative owned an offshore racer that he competed with. This was powered by two Lamborghini V12 engines and those were an entirely different animal. Tweaked to the limit of what was possible and without any attempt at a muffler that thing screamed. At idle it was ear shattering loud. Give it a blip and it was as loud as any military torpedo boat at full throttle, and at full throttle you better be far off coast or there would be a lot of unhappy people. Turns out the average life expectancy of offshore racers is pretty low, and competing at the pro level will drain the bank accounts distressingly quickly. So his wife put her foot down and made him stop competing and sell off the boat. Well his doctors may have had something to say also as they were talking about how how the repeated belting he got while driving that boat did a number on his back, and were showing him wheelchairs talking about how it was just a matter of time...

@@wtfiswiththosehandles You can't compared the cost of a brand new item to a 20 year old used motor. Yes it's tiny and uses few materials, but you are paying for the thousands of hours of research and design, the hundreds of hours of machine work with expensive machines and the man hours it takes to put it all together and running right. Things also tend to be way more expensive when made in small quantities compared to mass produced. This isn't a car engine that they have produced millions off, it's a tiny little art peace that they will make just very few of.

This would be a perfect engine for a model boat. I think you'll run into heat issues given that it's a scale v12 and would need a crazy radiator, but as a watercraft you can route the lake water itself as coolant the same way it's done to cool electric motors.

[@233kosta]

Too much risk of contamination there, I'd run a water to water heat exchanger.

[@LtdJorge]

​@@233kosta yep, would be the best way. Even better, use actual coolant (yeah it's made mostly of distilled water, I know) for the radiator part, and the external water for the other. But yes, heat exchanger sounds like the best option.

[@233kosta]

@@LtdJorge Yeh, that's what I meant by water-water HE, the internal loop would probably be 50% antifreeze or at least have some chemical stabilisers. Don't want to risk blockage or corrosion. But definitely better to use the surrounding water rather than air, it'd make the heat exchanger a whooooole lot smaller.

I think most, if not all, real engines run 12-into-4 equal length headers - 12 into 1 probably reduces the pressure pulses to a level where they are unusable. It may make a little more sense on a scale model, where the headers are extremely short and therefore tuned to unrealistically high RPMs
