Finally - the fuel system plumbing is complete! I added the final parts of the fuel return system today. Here's the 1/2" hole for the AN833-5D bulkhead fitting. The hole from the inside of the cockpit. Here's the...
I finally got to the point where I can make the firewall penetrations for the heater. The recommended way is to have the hose barbs for the heater penetrate the firewall, and just seal them...
The way the cooling system is set up from the factory, there is a hose coming from the top of the engine to the expansion tank and then down to the water pump at the...
I decided to check the junkyard again to see if I can find a better expansion tank there. I found what I think will be a good one. It came from a Renault van, and...
I've been staring at the fuel pressure regulator for about a year, trying to find a good way to mount it. I've seen it done mainly with adel clamps, but I really didn't like that....
The intercooler is used to cool down the compressed air coming from the supercharger before it goes into the engine. Cooler air is more dense, so it helps produce more power. The engine kit came with...
I received some more AN fittings in the mail today from Aircraft Spruce. I've probably spent several hundred dollars on these fittings - but I think I finally have all that I will need for...
Here is a view of a customer engine. I'm always amazed at the small size of the rotary engine. Note the machining for the engine mount. They have designed the engine to use the standard...
During my visit to Mistral Engines in Geneva, I had the chance to see one of their engines on a test stand. The system they have set up is very complete, and allows them to...
Update 20210918: I didn't install the Eggenfellner Subaru engine, so any post that references that can be ignored or used as a cautionary tale about how to avoid wasting many years and $50k. All this...
Yesterday, Feb 1 2006, I spent the afternoon at Mistral Engines in Geneva. Mistral is developing a family of rotary aviation engines for the certified and experimental markets. They have completed development on the 2-rotor normally...
I went to the local junkyard to try to find a coolant overflow tank. I looked in about 50 cars. One pattern I found was that the best places to find stuff are the "smaller"...
On my 8 with the intercooler, there is not a lot of room to have the coolant expansion tank sitting up very high. I had a custom tank built, but it really didn't solve the...

I designed and had built a new coolant expansion tank. I outsourced this to Canton Racing in the US, since they seem to have a lot of nice coolant expansion tanks in their product line....
The exhaust system has connection points, called "bungs", welded onto them for two sensors on the left, and one on the right. These bungs are for the air/fuel ratio sensor, and the exhaust gas temperature...

A great article by Steven Miller, chopped out of the airsoob Yahoo list. Excellent reading! I have to chime in after reading Marvin's post. He seems to have put a lot of thought into his theory...
I got my pipes coated with ceramic by http://Jet-Hot.com. It seems like it turned out ok. It cost about $200. I guess I'll know how well it works after I get them installed, and fire...

Here are a couple of photos that show some things I'll have to figure out about mounting the coolant tank. The coolant expansion tank is a Moroso racing tank, and costs about 99 USD from places...
Here are a couple of pictures of the old and new fuel pressure regulator. The original was set at a fixed pressure, and the new one is able to be regulated. The old one: The new one: ...
I installed the PSRU breather. The original design was simple, but in some installations there was a bit of oil dripping out. The breather should solve that problem. Here are a couple of pictures of the...
