Anyone ever consider an aircraft engine swap? Saw the Youtube video and it made me wonder.

Nope. It's an entirely different creature. For one the Red line is about 3300 rpm. It would most likely overheat unless you were on the hi way all the time and on and on and on. (IMG:style_emoticons/default/beerchug.gif)

Tucker used a H-6 intended for a bell helicopter. I looked up the typical rpm of a piston engine for a helo, 450 - 500 rpm. Not sure how he did it. Couldn't find much info on his engine.

Why? What do you see and possible advantages ?
An aircraft engine is made to operate at a fixed RPM.
You would have to add a source of airflow over the heads and cylinders.
Parts are far more expensive and less common.

It's like the flying car or the amphibious car. Sounds great but in practice they're not very good at any one thing.
The flying car is at best a marginal car or a marginal airplane.

There's exceptions, as in car engines in small aircraft, but these engines are reworked to better suit aircraft.

Spent my former life rebuilding aircraft engines. The only thing close to what we would want would be the Rotax 914UL or the 912S. They are 4cyl opposed with watercooled heads.. the 914ul is a turbocharged version. Turns good RPM as well

There are probably hundreds of aircraft with VW air cooled motors. What struck me about the Type VI and 6 cylinder 911 motors was how much they resemble aircraft motors. Porsche even licensed their 3.0 six (IIRC) to Mooney for their aircraft. LS engines are being used for everything from boat motors to aircraft engines. Just because it’s in an airplane doesn’t mean it has to be air cooled.

It would be amusing to see a car - any car - with a rotary engine (aircraft not wankel :-) ).

It's been done to a bug. Looks like it should be in a mad max movie. Exposed prop. (IMG:style_emoticons/default/wacko.gif)

The standard four cylinder Lycoming is 360 cubic inches making 180 HP

The Thunderbolt as shown in the link is probably a 390. They are built stout. Take a look at the length of that nosebearing. They are designed to turn 2700 - 2900 rpm max. You would need some really long gearing to make that work!

I know there are a lot of radial powered bike https://www.haulnride.com/radial-engine-mot...past-to-present

A few cars, looking for links...... aha, here’s one https://www.motortrend.com/news/airplane-en...dically-radial/

1st engine I ever took apart and "rebuilt". At school we just took them apart, measured everything and put it right back together. No new parts since just run on test cells.

I see O’Reilys has Flux Capacitors on their website for sale. Do you think I could fit me in my 914? I know they are engineered for time travel but who knows. Might make for a fun conversion.

Well, this is how it can happen. At least someone else put up the money.

For what you would pay for a serviceable aircraft engine you could build a nice T4 motor, so why? If you want HP you can go V8 or Subaru, My leaning would be to the latter with a turbo, but it's a lot of work and money you will probably never get back if you sell it.

My plane has a Continental 360ci, supercharged. Rebuild is the best past of $40k. As said above, very limited rpm range. No reason to consider it for any auto.

I've seen it the other way around, 914 motor in a gyro-copter.
