Subject: [FlyRotary] Howe "oil heat
exchanger"- what a joke
Greetings,
I spent about half a day
measuring my potential space for a real oil cooler, along with removing the
plumbing from the heat exchangers in the radiator. Once I got the lines
off, I was able to look down into the port, and could see just how useless the
heat exchangers are. This link shows a picture of the "cool tube" that
Howe sells for running lines: http://www.howeracing.com/Radiators/Index-Coolers-CoolTube.htm
Imagine this tube turned inside out, so the inside has the fins, and the
outside is smooth. Best I can tell, the oil runs through the middle, and
that's about it. Utter crap. All I was doing was making the oil
dizzy having to run through both of these :-)
I looked at the space
available, and can't fit the stock Mazda cooler anywhere easily. I
should be able to go with the Setrab cooler pretty easily though. Now
that I've done some measuring of the stock cooler, and since it's made much
the same way as the Setrab, I should be able to figure out how the size
of the stock unit compares to various Setrab sizes. I'll shoot for
something a little bigger than the stock Mazda unit, and give it a shot.
Cheers,
Rusty
Anyone remember who made
the oil coolers that caused the inflight fires on the 20b
pusher?
