What about using oil cooling of the cylinder jackets to aid the existing fins? You already have oil pumps. Oil, air and a richer mixture might win the battle.
Cooling this layout is a big question. Also a two stroke doesn't need 12 cylinders to sound right. Infact it will sound wrong. A six with the same capacity will sound like a twelve. So why not simplify it?
2 stroke is simpler and cheaper to develop and manufacture and also better power to weight ratio than 4 stroke. It is a project I would like to try once we have the 2 stroke version in full production. It has been a big challenge to get the 2 stroke engine to a flying state.
another informative vid Phil. great to see how the development has progressed - regards markc
It's beautiful, a work of art..
I can't decide if it sounds like a Merlin or an Alisson. 😀
Great work! Making it 2 stroke gave you more power with less weight.
Ah, but I'm so missing that 4 stroke sound
@@cabanford You can give me more than 4 strokes buddy boo ;)
Nice build 🔨👍! My neighbor owns a landscape company it sounds like 12 weed wackers on a mission!
That is a really nice engine.
I'm amazed this doesn't have more views
Subscribed for sure. WOW... this is so interesting!
Thanks for your positive response.

Could the cooling systen be run from a lobe on the crank,similar to the old style mechanical petrol pump on cars ?
Did you ever consider using the fuel as the coolant?
Great and impressive engineering - but surely the sound is all wrong for a Spitfire, it's more like a 90's F1 car.
Maybe they could fix it by making two - twelve cylinders fire all at the same time.
You need to put a sock over the microphone. 3/4 layers.
The sound of these engines. Are way different in person.

Ive worked on engines all my working life and this model is amazing But it sounds like a hairdryer 🙁 disappointing sound 😂😂
That crank looks bigger than needed.
Why not supercharge it, so the crankcase & crank can be simplified?
The solution is rotary valves. Compact, simple and a 4 stroke. Look up the HP .49 model engine and webra 4 stroke model engines
Why 2 stroke? If it was a 4 stroke it would have sounded much better.
Beautiful engine though.

no one would risk the unreliability, sounds terrible
Says you, Vince, you id10t.
Next step is a wasp!
