High Performance Oil Cooler Shroud

majuro15 · #1 01-07-2015, 07:44 PM

In one of my all night research binges, I stumbled across a fiberglass oil cooler shroud for the 10 / 540 that was supposed to smooth and increase air flow over the cooler. It had a fin inside the shroud and a round duct to attach the SCAT to. I thought I had bookmarked it but apparently sleepily forgot.

Anyone have any clue of what I'm thinking of and better yet, experience with such a addition?

In most cases, a stock cowl with stock baffles and oil cooler box runs just right. If in hot temperatures, a higher capacity oil cooler is just right. No need to reinvent it.

I haven't used one, but they do look interesting.

This is a 5" tapered into a 4" duct and works extremely well in California summers at 100 plus degrees.
I never see oil temps over 200F on even the hottest days and for the most part during the winter month I keep the butterfly valve closed all the way.
I added an extra 2" flange for additional air just because I heard of some 10s struggling with hot oil temps.
You may not need it just like Jesse pointed out but in case you do, this is what works for me.

Build whatever you want:

A turning vane (previous post and below) is easily added if you suspect separation at the small radius side of the turn.

I used the "45" listed at Airflow. Tight fit but works so well that even in the summer I would have to choke it down a little bit.

I've seen the Airflow kit. The one I'm thinking of was similar, but a little "smoother" shaped. They had a fin in the middle and the webpage even had some fluid dynamic screen shots of the internal air flow.

Not overly concerned about oil cooling without it, was just more curious and aggravated that I forgot to bookmark it!

The airflow site has those diagrams. They are in the "Oil Cooler" section. Here's a link.

Tim,

Should be able to find it if you look in your browser "history" pages.

I have had no issues with oil temps in my Rv10. I did make sure I sealed the heck out of the oil mount box on the firewall - every gap and seam was sealed. I also sealed between the oil cooler and the mount where there were gaps. I use the servo controlled butterfly valve to open and close the cooling source and in the summer I have never had a heat issue. In the winter, I can close down the air easily to control the temperature.
