In the Uk, on a classic car MsB, someone has posted pics of an engine rather too big for any car, bought by thier neighbour. Anyone here (Big Don?) able to ID it? It looks a little 'distressed'.

Looks like a four row radial to me. The 'corncob'. The bottom picture looks like a prop spindle. 32 or 36 stacks. Big mammajamma. I'm not a round engine guy though, so I reserve the right to be wrong. :)

Come on you're saying you wouldn't strap a seat onto that thing and go for a spin? (No throttle, no brakes. Just you, some goggles, a leather helmet, and some goggles. Also a lot of liquid courage and big gigantic brass ones that need their own harness)

More goggles. I need more goggles!

I need to read more carefully. And learn not to not to not to not to repeat myself. Not to.

The goggles, they do nothing!

Looks radial to me too.

You mean something like this (http://www.ronpatrickstuff.com/)?
Or maybe this (http://www.richard-seaman.com/Aircraft/AirShows/Miramar2004/Highlights/JetTruckAndMig.jpg)?

Yeah, it's a BIG radial engine, not a jet. There weren't that many 4 row radials built so it shouldn't be that hard to narrow it down. One possibility is a Pratt & Whitney Wasp Major (http://en.wikipedia.org/wiki/Pratt_%26_Whitney_Wasp_Major). Big mamma: 28 cylinders in 4 rows, 4360 cubic inches displacement, reportedly 3,000 - 4,300 horsepower depending on the version.

While doing a quick search for radial engine info, I found this radial engine motorcycle (http://thekneeslider.com/archives/2006/05/10/radial-engine-powered-motorcycle/) (!!!). What a freakshow! I have to wonder if the bike wants to lean hard if you try to accelerate too quickly. Be sure to follow the links on the page.

It would be nice to have some better pictures. I don't think it's a 4360, it looks too short and too enclosed. I thought at first it was a centrifugal turbojet (Whittle, GE) but I can't see where the thrust would come out. I'm going to the Patrick AFB library tomorrow, and I'll chech out an excellant book on aircraft engines, maybe I can come up with something.

The splined shaft in the bottom picture sure does look like the engine was intended to drive a propellor. It does seem to bear some resemblance to the R-1830 Twin Wasp. "Radial aircraft engine" does seem like a pretty good conjecture at this point.

It doesn't look like a Wasp Major - it isn't long enough. Possibly an R-2800 double wasp or an R-1830 Twin Wasp.

I found a cutaway (http://www.aviationtechcenter.com/images3/Radial%20Engine%20Cutaway.JPG) of some kind of two row radial. You can match some of the parts up to the ones in that guy's backyard.

Looks radial to me too.

Looks more radical, than radial, as in trying to fly with the front half of an engine...
