Oil filter kit or similar

I have that one mounted (in addition to the cooler, not as a replacement) on my Jota. Works well, has also a magnet to collect metal in it (but I also have a magnetic sumbplug... german paranoia strikes again...)
 
Note from Magnefine from 2009. The office in Michigan has moved since then

Yes, you can use the Magnefine filter with all grades of engine oil.

You say high volume and low pressure, do you know what the numbers are?  What is the ID of the hose you plan to install the filter. Our 1/2" filter flows about 4 gpm. If your system pressure is lower than 100 psi, a Magnefine will work very well.

Typically, you can use a Magnefine in any system that has hose clamps on the cooler line.

As for the by-pass valve, it is a differential pressure valve and will not open unless the element is blocked/occluded. This is a safety feature to make sure the system is not starved for oil should the filter become blocked.

The filter itself adds a negligible amount of restriction to flow, equal to about 2 feet of hose.

Ford was cheap and used one holding bolt for the coil bracket when it was attached to the firewall and only one "ear" on the bracket. Most European cars used two "ears" and two screws.
If the right bracket cannot be sourced out of a salvage yard..then someone would have to make some.

It's been done. If you Google "Ford coil bracket" you should find a local supplier. Here's a coupla pictures of ones in the US. The shiny one is even stainless.

Ken..that is the ticket, very nice!

I think Laverdas run on a lot less than 8 lbs,what is the filter pressure ?,magnet and change oil every 1000 miles,what happens if your running on a straight 50 weight,all your going to feed is the primary chain case,?

Pressure differential (8psi with the Magnefine filter) is comparing the pressure of the inlet side of the filter media against the resistance on the outlet side of the filer media. The pressure on the outlet side would only be zero for a few moments at start up. Once running, the oil would have some resistance moving into the engine bearings and galleries on the outlet side of the filter, therefor pressure.

Lets say normal Laverda 3c pressure is 10psi hot (probably lower) at 3000rpm. If the filter becomes clogged, the inlet pressure would rise to say..15psi and the outlet side would fall, say 2psi. Once the difference between the two hits 8psi, the by pass would open...pressure differential.

When the by pass opens the inlet pressure drops and the outlet pressure rises and the engine is lubricated. The by pass closes.

Works the same as any oil filter with a built in safety by pass valve, like most of them.

The 3/8 Magnefine offers resistance to flow equivalent to about two feet of 3/8 hose, or much, much less than 1psi, according to the engineers.

I think you would have to be very neglectful to "plug" this filter. The media is large for our 3 liter oil capacity.  

50w engine oil would run higher pressures (resistance) when cold with very little fluid flow and a filter by pass (8psi differential) would open. Without a filter and cold 50w oil you still have very low fluid flow and poor lubrication. Hopefully you would only run 50w when it was very, very warm outside. Factory recommended 20w50, which is what I run in my bike year round, with a filter.

Magnets alone do not effectively clean the oil..they are better than nothing though. You need a good filter media to do the hard work.
 
Anyone considered using an Earls in-line filter? They're a gauze filter type, 140 micron, and are usually used as a pre filter. They probably could fit between the cooler and the engine. Have a look on page 39 and 59.

"with the cooling fins from the link on the previous side."

Which link are you refering to?

Gotcha, thanks for that - KS Performance filters.

I noticed that the KS is a 35 micron filter do you think the Earls 140 micron version would miss too much?
 
let me say i am a member of the frequent oil change group
but there is a filter i've used on race car engines

nice as you can open it up for inspection and cleaning

Pressure is resistance to flow - simples.
Higher pressure = less flow.
Lower pressure = more flow.

Damn! If somebody had told me that years ago when I was studying engineering, I wouldn't have bought all those fluid dynamics textbooks  :D
 
I can't believe that no one has any experience with Scott's stainless filters.  They've been around many years and Scott has a sterling reputation with off-road riders.  I really like the idea of being able to open, inspect, clean and reuse a filter.

Lawrence,

the Scott Filter is the same as the KS and the same as the one I use.

Morison: not sure about the micron size. Generally I would assume that the more narrow the filter is, the more it filters. On the other hand at a certain point, it will produce a resistance, which might lower the oil-flow amount. I have absolutely no clue though when this would happen, don't have any of these fancy fluid dynamic books...  ;)
