Wow
Yesterday I replaced my original baffle seals with this same, thicker material. I thought my originals were pretty good but wasn't completely satisfied with the back corners, overlaps and transition at the inlets. I was able to install the new ones with only a couple cuts and they seal to the top cowl much better, overall a much cleaner install.
I flew today and have never seen temps this cool. #3 was down in the 330's in climb and my hottest cylinder, #4, only got to 370 in a climb to 10,000'. Cruise was +/- 350, whereas normally is around 370. Granted, it was a cool day in the mid sixties but nonetheless, it seems reworking my baffles, that I thought were good already, made a big difference.
I also tried something on my oil cooler, which mounts to the rear of the engine baffle. (Should get a picture). It seams to me that air can exit straight rearward through the cooling fins, but also through holes in the top and bottom of the oil cooler?? I took RTV sealant and closed off the holes in the top of the oil cooler, front and rear... oil temps never went over 155 (normally 170's). I think not only did this make more air travel through the fins but also decreased the amount of air pouring through the oil cooler exit.
Good day for me, maybe I can advance my pmag timing now
