|
|
Dear Listers,
The RV-8's cowling done and fits like a glove. I started the baffling last night and its coming along nicely. The fit on the sides and back are very good considering the IO-390 installation (and the use of the IO-360 baffle kit). The front baffling is completely different, however, and I'm slogging through the custom fitting.
But here's my question. I decided to put the top cowling on top of the baffling that I've got installed so far and I was shocked that the baffling appears to be a good 1 to 1.5" too tall!! Is this because of the IO-390 or is that just where Van's expects you to start in your "cutting-it-down-to-size" phase? That's a lot of snipping and fitting and snipping and fitting. I was expecting to have to trim some, but not over a inch...
Also, it looks like the over-sized oil cooler is going to fit nicely on the rear baffle with only a little "modification". But I'm not sure if the back, upper corner is going to clear the cowling. Since the cowling is sitting over a inch high right now, I've got no way to really trial fit the oil cooler and check for cowling clearance until I trim the baffling down. Worst-case I could put a blister on the cowling for the rear, upper flange of the oil cooler, I suppose, but that's kind of hokey. There is room to move the oil cooler in towards the centerline about 1", but then the mount will no longer line up with the flange on the outboard edge and will require more modifications.
Thoughts...?

Hi Matt,
I can see that you are doing your usual fine work. My baffling was about 1
to 1 1/2" too tall also - lots of cutting and fitting. It took me forever
to finish the baffling.
Wow! That's a big oil cooler. I found that the left, rear corner of the
baffling was very close to the top cowl. Be sure and do a trial fit before
you cut the big hole for the oil cooler.
Regards,
Don Owens

Hi Matt,
I put a number of paper clips onto the baffles to find the right hight.
Also made a strut to support the baffle where the cooler mounts.

Dear Matt,
Pics look really good. Have you given any thought to mounting the oil
cooler on the firewall and not having to worry about spacing at all?

I just wanted to thank everyone for the great feedback on this baffling cut-down procedure. I'm glad to hear that it wasn't just my installation!!
I'll post some more pictures when I get things hacked down to size and that oil cooler mounted.
