An rc car with this motor, is a beast.

[@None_yabusiness69420]

A boat would be cooler imo

[@coconutmallman]

I’m saying because I don’t know, but wouldn’t an engine like this be impractical for an rc car? Seems like it would be too heavy

[@just.jose.youtube]

​@@coconutmallmanit all depends on the size of RC car you build... ;)

[@Reiner_Markenfreund]

Thanks JohnnyQ90, the fuel distribution appears to be too rich in the centre cylinders and good to a little too lean in the outer cylinders due to the very different exhaust gas temperatures. This is probably because the full volume of the intake manifolds is less than the full volume of the cylinders before they merge and go to the carburettor. The speed in the intake manifolds is also a key to perfect engine running. At max torque, 83 m/s in relation to the mean piston speed is the key. If the intake manifold is divided into several segments, such as an 83 m/s segment for idling at approx. 800^-1min and one for 1/2 max torque speed, then one for max torque and the total cross-section 83 m/s at maximum speed, and if a whole cylinder fullumen enters this group before they are grouped together to the carburettor, the exhaust gas temperature for all 12 cylinders should only differ by a few ±10°. MpG. EISENEXE Michael Fritjof Mueller

[@GreenLantern814]

This sounds like an interesting and very difficult engineering challenge to solve for a typical hobbyist (I imagine the only way to solve it is to alter the intake manifold or make a new one.) It also sounds like it might be a very good reason to move to an ITB setup, as complicated as that would become.

[@bartboosman953]

Indeed. Easiest way is to provide a large plenum into which 6 (or all 12) equal length trumpets enter. One butterfly at the entrance of the plenum. And fuel injection in each trumpet. This is what Ferrari did from the 456GT on for their V12s. Before that they used one carb per cylinder (6 double carbs) like most other performance engines. This motor seems a bit odd, with nice exhaust manifolds but very crude intakes. Surely the builder can improve on this. And also drastically reduce fuel consumption and see a significant increase in output!

[@Imagineering100]

It will be another bit of junk from Enjomor. My v8 has turned out to be just that junk.

@@yourbigfan1777Right, and it doesn’t appear to have rubber bushings or any other type of vibration isolation. And yet the gasoline has basically no movement at all, no ripples or other signs of vibration. A V12 is pretty much perfectly balanced as far an an ICE is concerned. They’re known to be basically vibration-free.

[@Giuliana-w1f]

EFI would be really hard to do in such a small scale, speciallly multi point EFI (required for ITBs). But a second carb would probably help, that one seems too small for a 72cc engine

[@ncopp4358]

They were still firing. Otherwise they wouldnt be sitting at 80 degrees. Probably some issues with the valves or the carbs are feeding too much gas.

It’s more likely the other 4 runners are just restricted and not flowing as well

@@ncopp4358 ~75° is the temp of the coolant in the engine. Combustion temp is higher than coolant temp, 119° in other pipes.

[@KentRoads]

that revs up so nicely

[@TheDustyShredder]

Putting two 3-1 collectors before the main collector will help exhaust flow a lot. Additionally, having 2 carbs will help with fuel distribution since each carb is feeding half the engine, akin to stacked v6 engines. Finally, addressing the inconsistent exhaust manifold temp: that can be caused by fuel mixture or timing issues. Investigate the possibility of late timing in the outer cylinders and rich mixture in the center cylinders.

[@iacopotuttino5515]

[@kieren7763]

If you look close the cold exhaust pipes are the same colour as the exhaust flange there not firing at all thats residual heat

[@gheumann]

That is a thing of beauty. Congratulations, much respect. Absolutely brilliant. Some (constructive criticism) thoughts: 1) Ditch the 3D printed housings - they don't do the rest of the model justice. Either step up to a better quality 3D printing process or fabricate those somehow - machined billet, welded sheet metal, molded plastic... 2) How do you KNOW those cylinders are firing? Given the "one cylinder per flange" design - I'd say they aren't. 3) It boggs on acceleration - I suspect it is running lean or timing could be adjusted. 4) You've got distributors so I assume you have spark plugs - but what is that thing you're disconnecting after start? Reminds me of a glow plug battery..... Don't let anything I've said take away from your achievement. It DOES sound great but I think it can be even smoother.
