Corvair Engine

I believe that the Corvair engine has been overlooked by the Experimental Aviation community. I also believe that it will prove to be a very good alternative to a certificated aircraft engine, due to it's extremely low price, high horsepower to weight ratio, and apparent reliability.

We'll see!

 

Below are some links to other web pages dealing with aviation Corvair engines.

Now! On to my engines!

 

The two engines I bought had cars attached to them!

I bought these two cars from a gentleman who had them stored in a barn (for 14 years!) north of Dallas, Texas.

The cars were in absolutely great condition; no dents, dings, or rust! They were complete, except for keys! In fact, they were so complete, I was tempted to start the engines! I was kinda thinking "What the hell... I'm gonna rebuild them anyway; I sure would like to hear them run!" Well, in a few minutes you'll see why it was a great thing that I didn't!

 

 

This is the removal of the engine from the green car, a 1963 "700". The engine is rated at 80 hp. in the car.

 

 

 

 

 

 

Here are my treasures, safely home to San Antonio.

The engine to the rear of the truck is from the red car, a 1962 "500." It is a 102 hp. engine (stock)

 

 

 

After I removed the top cooling tin from the '63 engine, I found 14 years worth of rat and bug droppings! The "material" was so dense that the engines would have overheated in just a few minutes worth of running.

These pictures really don't do justice to the density of the droppings that were packed between the cooling fins on the cylinders.

 

 

This is a little closer shot of the rat's nest.

 

 

 

 

 

The bottom of the engine. It should fit in the Dragonfly cowling very well. The two brown things are the exhaust manifolds, and it is attached to the engine stand via the bell housing.

The bell housing will eventually be removed. (the propeller will go there) Visible also is the oil cooler (bottom left of engine)

 

Out of curiosity, I removed one of the cylinder heads. Sure enough, this engine has seen a lot of wear. The cylinders are obviously worn, and there is a lot of carbon deposits throughout the combustion chamber / piston tops.

 

 

 

I'll post more on the engine as soon as I start the disassembly for the overhaul.
