HB-YMM Experimental Homebuilt Van’s Aircraft RV-8
Here's the current view of my instrument panel design. The panel is out to get cut right now at http://www.experimentalair.com/ using their high tech water jet cutting machine. I've got the GRT EFIS Sport http://www.grtavionics.com/, Garmin...
From Vern Little on the Van's Air Force website: Belt deflection is an unreliable method of tightening the belt. Instead, use a torque wrench on the pulley nut and adjust the tension so that you get about...
Here's what I used to hook up the fuel pressure sender and the fuel pressure switch. I got this manifold from Aircraft Spruce. The rest is standard aviation stuff. ...
I picked up the 2.25" altimeter that I might use. I have not yet taken it up to see if it works right, or brought it to a repair station. I need to do this....
Here is an image that shows the sizes for many of the round instrument panel cutouts. I had a bit of trouble finding this, so I thought it would be useful to post it here. ...
To test the fuel system, I hooked up some fittings between the intake and return fuel lines just outside the fuselage. I put a + on there, with the "schrader" valve that comes with the...
These are just some random shots of the cooling system plumbing. Looking up from the bottom center to the left. Black corrugated split loom hose cover is over the hose that returns from the cabin heater. Looking...
I started my engine this afternoon. It took about two seconds of pressing the start button, and it fired right up. Nice little rumble. Very smooth. I used my wife's camera to take some video, but...
I hope this is the final version of the coolant tank. This is the second one I had built at Canton Racing (http://www.cantonracing.com/), and it is as nice as the first one. The first one...
Now it's time to start wiring behind the panel. One of the most difficult steps is to figure out where to mount things. Once you've done that, the rest just sort of falls into place....
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. Here are a...
This is a great article by Doug Rozendaal. In response to the RV-List thread on turning back to the airport in the event of an engine failure after Take Off I have assembled this editorial. To...
Here are a couple of quick photos of the contactor for the alternator and starter. I really don't need a starter contactor, but to simplify wiring, I've connected the alternator to the starter, and the...
I mounted the forest of tabs ground onto the airframe. I ran one ground wire back to the batteries, and two ground wires from the engine to this single location. All the fat orange wire...
The supercharger needs some method of boost control. Originally, this was going to be electronic, but for a variety of reasons we're going with a manual boost control, or wastegate. The boost control will be next...
The ECU box needs to be mounted somewhere cool, dry, and somewhat isolated from vibration. The massive wiring bundle does not leave a lot of slack, so finding the best place to mount it is...

The standard 3" hump hose that came with the kit was not quite long enough. Unfortunately, the 2.75" diameter hump hose only comes in 3" lengths. I really wanted a 4" length, so I found...
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...
