Bob, I've been tweaking inlets, outlets and before I knew it, I had a new cowl. I'm currently working on a new cowl bottom that incorporates the ideas you mention to increase suction at the cowl exit.

To address the intake leaks, I'm using 4" (101.6mm) Scat for engine and oil cooling inlets.

Looks like we're running the same CHT temps, but I would like to get the center cylinders to run a bit cooler. I'm sure you're on the same path.

I'll do a blog once I get the new pieces installed.

Hi Bob,  Although I live in WA, I live in Exmouth which is 1200km North of Perth. My 601XLB is also up here and I now have about 50 flying hours on it. I have yet get my Nav endorsment but hope to do it maybe next month. I have an EA81 as the power plant but would like something with a bit more grunt.  But at least it flies!  It is also very easy to fly. A great little aircraft.

Hi Robert only just seen your friend request from January because I had an old page with my old email address and my old 601XL In was not ignoring your communication but just not thinking that there would be activity on my old page which I now deleted Hope to see you one day I am at Bunbury and  I now fly an 601XL-B (photo's on this site) Merry Christmas greetings Guido
