The OP has the right idea. This car/airplane engine has been done more than once.





A few years back I was staged in back of a jet dragster. Now that was an experience.

Use Tesla style running gear and a gas turbine running a generator.
Been wanting to do this for years in an aircraft, gas turbine running a generator, attached to a glider, altitude record for electric powered plane.
All I need is a huge pile of someone else's money.

Just use a radial. It'll fit, no problem...

And people have put turbines in motorcycles even - Leno's got one.

That is pretty impressive (and funny). The guys have to wear (David Clarke) headsets because of the noise of the engine. I wonder if they installed an aviation intercom as well. If it is a 7 Cylinder (looks like it) from a Cessna then it is most likely a Jacobs radial engine from a C-190 or C-195 with either 275HP or 300HP. At "cruise" setting (I believe somewhere around 2,100 RPM) the engine will burn 14 to 15 Gallon per hour.

I think an Intercom is installed, if for no other reason than what you said, the incredible noise. I also saw another video that must have had a feed from the intercom as he could be heard quite well.

The owner said the mileage was about a gallon per block. Certainly not gonna win any accolades from Greenpeace...

Since we are talking aircraft motors. Has anyone ever seen this truck? 3 Pratt & Whitney J34-48 jet motors.

Shockwave.

It might hurt the resale value of a 911, but heck, if it makes you happy, go for it! If you do it, please post a few pictures ...

Air-cooled GA engines are built to looser tolerances for better reliability at low RPMs. Spin them above 3k for any extended period of time and you will probably lose the reliability advantage.

The Piper Arrow I fly has a max continuous limit of 2700 RPM (@~200hp). Controlled by an adjustable pitch prop.

And they only hold a max of 8qts of oil.

But, I'd love to see you try and what solutions you come up with. I'm sure it could be done....somehow. The only reason the aviation engines cost more to rebuild is because they're...well, FAA regulated mechs $$ working on them. Everything's a lawsuit once you're airborne. If you did the work yourself you may not have that issue.

Why not just go down to a local airport, learn how to fly, get your private pilots licence, and save money on destroying a good Porsche and a Cessna or piper in the process.......

The W 12 was a very popular Pre WWI engine that was modified for many subsequent uses. https://en.wikipedia.org/wiki/W12_engine

HorstP pretty much covered most of it in his post but to add a few things...

To quote my ground school teacher in high school, "If we put an airplane engine in your cars all of you would seize them in a week with all your getting in and revving them and driving them before they warm up." (Yes. Ground school was a course in my high school!)

An air cooled engine designed for operation only with a careful check listed startup, regular tear down based maintenance, fixed low RPM operation, and cooling from a completely consistent high speed air source coming from the direction of the crank flange instead of from above.

Water cooled engines will let you have a bit more wiggle room but the fact is it is a lot easier to adapt an automotive engine into an aircraft then the other way around.
- Oh and a turbine is no cake walk. Find Leno's video about what he had to go through designing his "Jet car". An engine that idles at 80% of full RPM is not easy to use in a wheel driven car.

Correct me if I am wrong, but was it mentioned why Aircraft engines are designed for lower rpm??

The speed at the tip on the propeller is the limiting factor. When the propeller tip goes over the speed of sound it loses lift and becomes way less efficient.

Aircraft engines are designed for much lower speeds than and automotive engine.

Here's a shot of the circa-1960 Porsche 678/4 aircraft engine that Dennis Frick (Europa Macchina) restored for me a few years ago. I found it in Trade-A-Plane. It was set up on a portable stand, and we ran it at the 2009 Parade concours. Twin ignition, dual fan belts, gear reduction unit (about 50%), dry-sump lubrication, etc.

My Turbo has an 930/67 aircraft engine (at least crankcase)
