Improved Cooling Part II

I’m almost done with my modifications to my plenum to improve the cooling air seal. I’m adding silicone everywhere, it seems. Along the way, I decided to see what the SE manual said in this regard, and I have to say, this is a picture that definitely should be in the XL manual. Aside from […]

Improved cooling part I

So, although we’ve never had issues with our engine really running hot, it’s not been cool either. I’ve been a bit worried about it since our constant-speed prop will be shipping soon. With it, a much higher RPM will be available to us for climb-out, and with higher RPM comes higher engine horsepower. That’s all great, in […]

Pressure Sensors

My buddy Andy noticed that I didn’t have good pictures of my oil and fuel pressure sensors (he’s at this stage right now), so here they are. Note that the oil pressure sensor outlet is right next to the temperature outlet. I’ve remotely mounted my sensors, and I have a switch as well as the […]

Air Filter Mounting Location Selection

Obsolete: We are currently running without an air filter as it restricted engine RPM. Here you can see the new rectangular air filter by K&N where I think I can install it. The round filter won’t work, but I think we have a good shot with this one. We’ll see. New air filter

More on Engine Oil Cooling

It’s Deja Vu all over again. I swore that we wouldn’t fly with these soft aluminum tubes again, and here we are about to do it. So, a couple of things, we’ve studied carefully how you’re supposed to insure that your flares are good. Secondly, if we find that the larger hard tubing does give […]

Engine Exhast Pipe Wrapping

I’m just now posting pictures of it, but here is out exhaust wrap. This seems to have helped our temperatures, but it’s hard to say for sure how much. Based on everything we’ve done, I’d say probably 10 degrees on our oil temperature. Exhaust wrap to keep from radiating heat to oil sump
