Oil Cooler (a different approach)

[ducatiz]

The problem with mounting it upside down is that a significant amount of air will  be trapped inside of the cooler. With the feed and return line at the bottom, there would be no easy way to avoid the air trapped inside.

i revisited this post -- it's not an issue, check out the MTS 1100's parts manual, page 80.  The MTS's oil cooler's intake/outlet are on the bottom.

The flow of oil is vigorous enough that it pushes the air out.  the oil cooler is a serpentine inside, not just an empty box.  all the air gets pushed right thru, no issues.

you can flip it right over if you like.  the air will not stay in the cooler when oil is flowing thru at high pressure.

+1, this is how heat exhangers (oil coolers and the like) are designed. Its a back and forth 'maze' pattern.

I might be using an oil cooler from an airplane. They are a little different in design. Hopefully I can find one small enough. Maybe a hydraulic fluid cooler.

i've got about half a dozen coolers lying around trying to make one fit on my '95 900SP.  I want to move the cooler under the front cover, F1 style.  the biggest problem i've found is finding one off the shelf that's the right dims with something to mount off. 

Bob Miller used to make a kit, but he's long gone from the biz..

under what front cover? front valve cover or front fairing?

DT mounted his up under the front fairing, I think it looks really good - would be great on a fully faired bike.

under the headlight, inside

What type and size are you looking for? My Multistrada one is just sitting around gathering dust...it used to be mounted up front under the headlight, so it has mounting tabs.

narrow and thick..  needs to be the same volume but narrower than stock, about 6" max

there are a few brands out there, i just gotta find them.  got pics?

I can take some pics and measurements tonight if you'd like. I think it's basically the same size as all of the newer oil coolers though...probably too wide, but I'll double check.

Question: Are you planning on mounting it to frame/steering stem or to the triple? I think mounting it to triple/forks would be problematic, with the lines constantly moving about (and getting extremely hot, potentially).

mounting it to the subframe that connects to the steering stem.  right under the headlight, hoses will run underneath and hang a little.  i've seen it done and it works well without impeding steering any.  the side covers hid the hoses.

I have a friend with a 96 900 SS/SP (full fairing) that is running an oil cooler in that position (same cooler as stock) along with the stock cooler.  With both coolers here in the desert keep his oil temps in tune during the hot summers.  He just has a cover to restrict the one behind the headlight during the winter months.  A local Duc independent mechanic plumbed the lines and I remember correctly they are plumbed sequentially.  I will have to ask about it.

please do, although i don't want two coolers!.. sounds like he might have just used a small valve spring type..  they are narrow and thin, prob no more than 0.2 L capacity... i've seen one that is about the same width but is thicker with 0.6L capacity, which is about the same size as the factory one.

I've seen this, and I like the idea a lot. Here's the one I've seen, sequential oil coolers:
