Steve Witman inverted motor

[Roland M]

Looking people who have inverted motors and would like to talk about
it.
Why there is a group of diesel enthusiast"" 100 members"" who want to
fly diesel planes using production diesels.

Due to weight conciderations and need,no redrive.
VW/Citroen-Peugoet/Daihatsu-Toyota all have all have all aluminium
motors that weigh less than 220lbs and can produce over 100 hp.

Not everybody lives in America with cheap fuel "" do not go there! due
to other goverments high goverment taxes)

Questions what problems did you have and would you do it
again/cost/touble shooting.

That engine is not the easiest to find. It was a lightweight aluminum V-8
installed in Buicks and Oldsmobiles during the seventies. It turned the
prop at crankshaft speed, had high compression, and put Steve Wittman into
the bushes a couple of times. The last I paid any attention to the engine
it had been sold by GM to Rover and was being used in Land Rovers.

A man adapted a similar engine to his Beachner Special and flew it for
several hundred hours, but not inverted, until it killed him.

There is a fellow in Canada who is flying a Bearhawk with the rover V-8
in an upright configuration through a PSRU. He actually mmanaged to fit
it inside the standard aircraft engine type cowling. Here are some
pictures:

I don't know of anyone using them, but some of the 3.8 to 4.3 liter 90 degree V6
engines look attractive for the inverted direct drive application. They should
produce between 130 and 150 horsepower at around 3200 rpm; and should be easier
to maintain than the _nearly_ antique Buick/Olds engine that Witman used. I
also believe that they are nearly the same weight.

I am also hoping for some of the same user information on the inverted direct
drive scheme, as I would consider one myself--if I ever get to that point.

I did not know that the diesels were now that light! It makes them attractive,
especially with all of the difficulties in finding a reliable supply of unleaded
fuel to make the automotive FADEC systems function reliably.

HUH... well I hope you have better luck with the 90-degree GM V-6 in a plane
than I've had with it in a car.

What problem have you had? I have owned three of them, and found them to be
reliable and nearly bullet proof.
