I use two K&N filter cans on the racer. 350 pound burst cans. One
would be more than enough for an airplane at 6 or 7 thousand RPM. Most cans have
a bypass delta. So if the element gets lots of dirt in it or the flow gets too
high the element is pushed down away from the cover and oil can still get
through the filter head. When this happens, the oil is not only not being
filtered, it is now gathering up the debris already removed from the oil and
passing it along in the outgoing oil. Or if the problem is element
collapse, then pieces of element paper are sent down stream to the
bearings. If that filter is just a bug screen, then no problem. If it has a
paper filter element, cut it open and be sure it has more than 125 sq. inches of
media. If that can has no bypass feature, element collapse just shuts off the
oil supply. The stock can is small and light weight, but, it is in a
street car with a low duty cycle. You should have cut open the can after the
first hour anyway, looking for scrap metal and bits of sealant. Very nice
workmanship.

The only one that I found on eBay! I was watching for years when
I got a notice that one was listed and then I won the auction. I think it came
out of England. It still wasn't cheap but had never been used.

I don't remember the model number and there isn't one that I can
see on it.
Todd I too am using the laminova-- not started the engine yet and won't
for a while--
Which model did you
choose???
Thanx

Hi Andrew;
I put one of these Laminova exchangers from Mocal in my
plane.
Very compact but still a few pounds, but it seems to work well so
far.
I used to see better oil cooling in climb than water cooling, but in
cruise I had better water cooling than oil cooling.
This was likely from my old, good looking oil cooler scoop,
which I don't think was very efficient. I've cut that off and changed it
to more of a P51 style scoop. Still looks ok, but it should work much
better, so when I return to flight I'll not be able to say definitively if
any improvements are due to the Laminova cooler or the improved airflow.
However, so far in static ground tests my H2O/Oil temps are quite
close.
Todd waiting for the smoke to clear
