Can anyone guess what this is and what it belongs to?

wow ill take it .

turbo CIS with 964 looks.. maybe some racecar engine from the 1990's

Porsche 3.2 engine for aircraft use. Pretty much all repurchased & crushed by the fatherland.
Neat items like gear driven cams, dual ignition, others

[silverc4s]

Plane was a Mooney, I think.

Love the redundant fan belts. This would be a cool thing to have.

I read somewhere that Porsche ignored, or did not allow sufficiently for two major factors in the design of an IC engine for aircraft use:
1. The load on the engine is high and constant compared to automobile requirement.
2. The weight of the entire aircraft is impressed across the crankshaft bearing surfaces while underway.

Someone had a nightmare & decided to make these engines all disappear before the lawyers got started..

Anyone here have additional/other information about this project?

This is an amazing statement that when I really thought it about blew my mind. Gonna do some more research on this...makes sense though

1) obviously was considered and established certification.
2) no, this engine had reduction gearbox with prop shaft and thrust bearing.

Silverc4s was the first to guess. Here is a photo of the plane that it belongs to, taken at the Deutsches Museum for Airplanes a few weekends ago outside of Munich.

In my years of flying I never had the opportunity to hear one. Must have been the sweetest sound in small aircraft.

Hahaha mooney got porsche to pay for the certification of their streched fuselage then dumped them.
