I have not yet addressed the area around the ring carier, but as far as I'm concerned, this is how you do the perimeter:
One piece of rubber and even clamping at the fasteners assures minimal leakage. I have a few hundred hours on it now and the edges of the seal show perfect contact with the upper cowl.

Curious if people have better luck with more rigid and traditional baffle seal material than what Van's supplies. I have a few spots where it "puckers". This may be my "it's too cold to fly" winter project.

This looks quite a bit like the Bonanza "go to" baffles from D'Shannon. I installed them on my Bonanza and almost never see CHT's above 380- and that only in climb on a hot day. (Of course it also has cowl flaps).

I think there should be an HBO Special telling us how to do this. Lacking that, a youtube video would do...
Carry on!

The ?HBO special? wouldn?t last very long ? this is a lot easier than it looks!
I discuss the ?how to? a bit in this thread:
If anyone has any questions after seeing the above ? shoot. I?m happy to share my methods.

My biggest head scratcher was at the intersection of the baffle strips and the parts attached to the lower cowl. This include how much to trim off Vans baffle kit at the air inlets.
It seems to be an area that is hard to photograph and the baffle instruction are sparse in this area...

Baffle Seals
I used the one-piece with backing strips method with the Vans material. The back and sides are not too difficult to get to follow the contour of the cowl exactly. The front parts are a little more challenging, but I think can be done this way also.

Engine Mount Covers
I live next door to a real craftsman who showed me how to make these round engine mount covers that look like they belong in a bra... They were hammered out of 3003 soft sheet, annealed once during the process. I had to rivet an extension on to the front baffle near cyl #1 because the gap was too wide to fill with RTV.
