I agree from personal experience Paul. My rad is under the engine,

the

only possible
place to put it.  I put an exit duct on the rad and the cooling went

to

hell, had to remove it and leave it open to the breeze.
I now have big louvres on the upper cowl above the oil cooler, so

it's

probably about as good as it's going to get for the oil.

I forgot to mention yours Perry. Sorry.


BTW Perry is using a tiny water rad compared to all other rotary
installations I have seen so far. My guess is about 13 by 15 by 1.75.
What are the dimensions Perry.

Paul
That makes 195 squ. ins.
Don't forget my two little air conditioning rads. Two at 9 X 11 is 198

squ.

ins.
My 2 square inches worth.
Approx. how long do my runners have to be to get some more Jipp. with my
2.85?
Ian.

I was referring to over all volume. How thick are your cores?
Paul Lamar

2.5 inches.

Ian

No wonder they cool so well. What year and make car are they from?
Plus being straight out like that the back side is much more open
than say a 45 degree mounting.
