After all mistakes, mis-purchases and re-do's which were almost half

the

cost, I spent about $11K.  My RV-6 weighed in at 1095 lbs. wet with

IFR

panel but less upholstery and paint.

The conversion added about a year to the project(I think).

Dave where did the oil cooler wind up? Got any more pictures with the
lower cowl off?

the engine you can see the rad.  36 more flight hours and I'll come show

off in Camarillo :-)

I know that I am going to have to trade some of that oil cooling in for

some

water cooling.  I have an unusual cooling design.  The air comes in the

two

front inlets, then through the oil cooler on the right and the

intercooler

on the left.  Then it pressurizes the cowl and flows down thought the
radiator on the way out.

I was expecting water to be the problem child all along.  I knew it

would be

important to 1) seal the cowl well so the air had to flow down and out,

2)

minimize heating of the air from the exhaust and turbo, 3) use a good

exit

duct to help suck the air out.

I have a few ideas for improvement on each of those fronts, as well as
possibly ducting some cool air directly to the rad.

Thanks for the picture Dave. Wow! Nice big oil cooler! Real thin.
Should work just great at climb speeds (low dynamic pressure). I thought
that was the water rad when I first saw a picture.

What does the rad air scoop look like?

Dave,

Congratulations ! If you have lots of oil cooling and need a little more
coolant cooling, a possible easy fix could be to try a Bodine heat
exchanger. They mount between the block and the oil filter and have an in
and out coolant line. They came stock on some early 90's Subarus. I don't
know how easy they would mount to a 13B but it might be a lot easier than
cowl changes. I have seen these work as the perfect solution to your exact
problem, only on Soob conversions though.

It is best to keep the oil cooling separate from the water cooling.
The oil cooling will still work at 250 F while the water is boiling
over at 250 F. Read my article on the web site below on How to Cool Your
Wankel.
