"cool collar" - cool your oil filter
I came across this today:
http://www.drivewerks.com/tech/cool_collar.htm
Basically an alumninium collar with fins to fit over your oil filter.
quote:
Bench tests, as well as road tests on both water- and air-cooled engines, have demonstrated oil temperature reduction of 18 to 23 degrees with the
Cool Collar
Thought it was interesting anyway.
Guess it won't go too well if you're stuck in stationary traffic.
Sound like a good idea / bad idea?
Cheers,
Greg H

Im sceptical how this can work as the oil filter is just a small percentage surface area of the whole engine that the oil circulate in. I wonder if
better results would be obtained if ribs are welded to the sides of the sump (not the bottom!) to increase its already larger air flow, particularly
as it is in a better position to get some aif flowing past it.
The oil filter collar surely cant make the tempo worse but is it worth the investment. I always read sales patter with contempt - they never say their
product is crap!
Has anyone tried one?
Darren.

Not so sure of any real benefit of the cooling collar, however I have seen a 'magnetic collar' results on a filter. Very impressive.
This collar goes around filter and contains small strong magnets which trap the minute metal particles in the filter which otherwise would pass
through.
Similar to a magnetic sump plug, which always seem to have something on them. A nut attached on one I removed 
Where that came from I never found out.

You could probably do something similar with the oil filter much cheaper by taking a magnet out of something like a microwave (preferably a scrap
one!!) to stick on the side of the filter. I suppose it could be held in place with tie wrap or similar.
Most DC motors have curved stator magnets. Not sure how strong (magnetically) they are but they should attract small particles OK and hold them. May
be bonded in tightly though so the can could be carefully cut to leave them intact. Need to find something where the rotor is approx same diameter as
the filter. My only concern is if there is a build up of particles on the inside of filter coupled with a magnet that is not quite strong enough could
leave a concentration of magnetic nasties that become dislodges. Frequent oil changes would reduce this risk.

Metro Turbo used a small oil-water heat exchanger that fitted between the oil filter and the adaptor --- could be adpted to Ford engines with oil
filters that use 3/4" UNF thread.
One othe the adavantages is that it not only cools the oil when hot but warms it up quicker from a cold start.

These clip-on filter heatsinks are snake oil .. They might lower the temp of the filter body locally, but not enough to impact the temp of the oil
passing through it.
Spend your pennies on something more useful ..

I very much doubt it would be of any effect-- you can get any results you want in a lab for bench tests. My engine uses the same filter oil cooler as
I suspect the xr3ti as you describe and it works pretty good up to 200-300hp on a turbo engine.

In principle this gadget can also heat the oil if the environment near it (e.g. turbo, exhaust manifold ?) is hotter than the engine oil. If it
really works, then something hand made from alu foil would do the same trick. In any case, they should have painted it matt black, and put something
like heat conducting compound (used for heat sinks in electronics) or even paraffin oil to improve the contact between the filter and the heat sink.
Sounds bogus, but cute for "street" use to impress the birds/chicks.
BTW, why are they called birds in the UK and chicks elsewhere. Are UK women bigger?

A lot of bike engines have them as well. Fireblades have a removable one which probably could be put to use on a car if the thread was the same, Ive
got a a spare one sitting in the garage if anyone is interested in trying.

we use a custom made heat exchanger on one of our raec cars as we were having problems with engine temp on warm days. Our was made out a formula
renault matrix but re housed for the correct shape and connections. Works a treat and sits nicely out of the way.

Chris,
I'd be interested in trying it as my car seems to take a bloody age to warm up and I could fit it at the same time as remote mounting the filter
this winter (as it sits too low!).
Do you fancy parting with it?
Cheers
