Without measuring i believe it to be about 3/16" thick and it is avery nice piece. I have used mine for several years and it works great to regulate the oil temps between summer and winter.
Yes I may bit optimistic but I just want to leave the option open. My oil cooler install has it sandwiched between an inlet and outlet duct so I want to have enough room to install it later by fabricating a spacer the same thickness as the shutter.Seeing that you live in So Cal, I'd wait on it. I've had mine on and off during testing over the last few months. My oil temps get up fine in winter temps down to the teens, but I have piston oil squirters. A pretty easy install on a flying plane if you feel you need it. YMMV.
Mine is very effective (IO-360-M1B, stock baffles, stock oil cooler location on the aft left baffle). I can control oil temp to within a degree or two by adjusting it via push-pull cable in flight, and I have about a 20-30 deg F range between open and closed. My oil temps have always been fine, usually on the cool side (low 180s even in warmer weather, 150-160 when it's cold, but closing the shutter brings it right up to 180 or so). Stock oil cooler, too, and I fly WOT pretty much all the time.
I'm very happy with it.
Wow, that sounds great.
If you have any pics of your install, I would love to see them. Maybe I goobered something up and am letting air bypass or something.
I am not seeing anywhere near the result you are getting from it; same engine, same oil cooler, same location.
Thanks,
Rob
