Can anyone identify this Flat 6 Engine & F.I. setup?

[jamesweyand]

I've been getting questions asking what this fits so I figured I would post this and ask the flat 6 experts out there to see if anyone knows. I really don't know if it's 911 or Corvair or an airplane avaition engine! I'll enclose a couple pics but there are more pics at the aucstion which is # 130286850369. Thanks for your wisdom, Jim

Well, I guess its both, Corvair and Aircraft:

Cool engine!!

Hey did anyone by chance see the "how it's made" show where they were showing how an aircraft engine was made?

The engine was very similar to a Porsche engine.

One interesting thing was that they used some sort of silk thread and and adhesive that is supposed to keep the case halves from leaking.

I wonder why we don't use anything like that.

Definitely Corvair but probably not aircraft with that intake/inj. Maybe a sand rail or dune buggy of some sort.

Thats the way they put them together, the tolerances are not nearly as close as the Porsche engines, use a #50 silk thread and Permatex Aviation sealer on the case halves.

Here is a C65 case, look how course the case sealing surfaces are:

single ignition. nobody would fly it. Boat maybe, not aircraft.

Looks like Hilborn FI on a Corvair,......

I would have never thought that the tolerances on an aircraft engine would be so much less than our Porsche engines.

Thanks for showing those pictures!


Ya learn something new every day!

Its done for survivability, Aircraft engines can run with very low oil pressure, and for quite some time without any pressure at all. The engines are somewhat loose compared to building a Porsche engine.

You guys are awesome. Thanks for the input, feel free to keep the comments coming if you know anything else. Jim

could be an engine out of a military power generator. Some were modified by early expermental a/c people. somebody post on EAA.

It appears to be an early model Corvair, converted for aircraft or air boat use. It looks like it has an adapter in place of the bell housing or the bell housing was cut down. The prop would mount to the flywheel end. The engine top cover is an aftermarket piece or home made & has an aftermarket breather. On the rear (pulley end) the oil cooler has been removed and an adapter added for remote oil cooler. And flare adapters have been welded to the filter housing at the 11 o'clock position above the crank pulley. These are used for a remote oil filter. The crank pulley and bracket are aftermarket, maybe used to run the Hilborn.

All in all, a pretty rough engine.
