1 cubic inch V-8

[griz]

Here is a guy who wanted to build a very small scale, yet running, V-8 engine.  Amazing.

That's a quarter beside it:

Cool, that's even smaller than this:

Being 2 feet tall would be a lot of fun.

Gas guzzler! 

He should have made a miniature four-cylinder instead

Cracks me up.

Yeah, but I bet it won't take a supercharger.

I would hope his next project is a Pratt & Whitney R-2800 Double Wasp.

This one, home-built, blew my mind.  Looks like the pushrods are like fine sewing needles. Supposedly, it runs.





Captured off a craftsman's site, but can't give pic credit.  Sorry.

I'd like to see a V-5. :D

here's a Radial you can just buy

The detail on that is incredible.

I spent enough years machining the full size parts that I can't imagine what it was like to make those.

I can't even deduct points for it having the wrong rear main seal and crank flange.

Love that tiny Ferrari.  I was amazed that he got the tach to work!

Yeah, but I bet it won't take a supercharger.

I'm actually surprised that it runs at all naturally aspirated, considering how small the valves are. (remember, when you cut a diameter in half, you cut the flow rate by 3/4).

The 1:3 scale Ferrari is absolutely mind boggling.  I've seen that video before, and I love that the entire car works.  He taught himself glass blowing to make the bulbs.  Watchmaking to make the gauges.  If I recall, the only thing he didn't make or machine himself was the transmission, as the gears were too complex for his skill level and equipment.  I really love that he worked to tune the exhaust to generate the "Ferrari music".

I'm actually surprised that it runs at all naturally aspirated, considering how small the valves are. (remember, when you cut a diameter in half, you cut the flow rate by 3/4).

I would expect it to go the other way, as another consequence of the square-cube law.   Making everything half-size gives you 1/2² the flow rate, as you say, but the cylinder volume would be 1/2³, so the smaller you get, the easier I would expect aspiration to be.

Or I'm smoking crack again.
