Miniature V-12

I got away from this project for quite a while but finally got back to it and made several revisions and went with different springs in the valve design and it runs much better. I have forgotten how to add a video but will give it a try. If it doesn't work I am open to suggestions.   Gary[youtube1]https://youtu.be/30PnhI58krM[/youtube1]

It's uncanny how much like a full size Allison or RR Merlin that sounds. Very cool, and beautiful work!

Very well done and sounds great!  Do you have any more details on the induction and how you're feeding air to those cylinders?  You've managed to hide it in all the pics and video

I have to add my congrats. Well Done and I like the sound too.

Thank You for sharing.

Thanks for the comments guys. Now for Mike R. asking where is the air coming from and where does it go. I attempted to hide the air intake hose and apparently it worked. In the photo you can see the intake nipple. It is below and on the back side of the supercharger. In the video I angled the engine so the one upright on the stand hides the hose. The heads have a modified version of Chuck Fellows sleeve valve system.
