In my plane the largest radiator I could fit under the cowl and not
under the engine was an MR2 radiator. Its core size is 26 x 12. What
radiators are the high HP p port guys using? Primarily I would be
looking for size,material and number of cores. If you used a remote fill
container with the radiator cap, did you buy it or make it? Aluminum
welding isn't easy to learn and even more difficult to have the
equipment to do it in some places, so an off the shelf version would be
nice.
However, if you cant get one find a way to make it. That requires
dimensions. Next time you are in the hangar, take a pic of the cooling
system and send it over. Notes help, and a measuring tape in the picture
is worth its weight in gold.

The ideal core is out of a Dodge pickup. Probably overkill. With our
asymmetric motor mount and motor plate the rad core will fit vertically
on the plug side of the engine. The turbo will also fit with the
asymmetric motor mount. I don't recommends using the stock Cont. mount.
The motor mount is the last thing to be designed. First one fits all the
major components. Then one builds the mount around them. A good 3D
program like Rhino is essential. The stock cowl shown will work fine, No
room under the engine with a nose gear for the rad core. Several
airplanes are flying with this arrangement. Nothing new here. I still
need the dims on the firewall hard points to finish this..
A stock Corvette pressure can works well.

Paul Lamar I will confirm the dims of the mounting points today after
the sun comes up. The stock Cont mount has a few more bars than some of
the other mounts, but the only ones that are in the way are the ones for
the retractable nose gear brackets. I am holding out hope that I will be
able to make the retracts work at some point. Now that I have the
radiator mock up in the cowl, the tubes aren't in the way much at all. I
cant get a Dodge truck radiator in the cowling- 14 inches high is about
the max and be able to close the hood. The MR2 rad gives me a few inches
either end, and room above and below tor get my hands around it.

The Toyoto MR2 would not be large enough. That is a low continuous power
engine compared to the Dodge pickup. The Dodge rad can be cut down as
you will need new aluminium end tanks anyway. The tubes run side to side
so no problem cutting it down.
What is the height of the firewall?
The cowl on the Wheeler is extra long. One of the things that must be
addressed is the heat from the turbo affecting the strength of the motor
mount. Brian is dealing with that issue now. I can incorporate the
retracts into the front MM design. There is plenty of room behind the
eng for the nose gear. If you still have the Viking gear send me some
pictures. I may be able to use it.
------------------------------------
I found some pictures. A retract nose gear is a piece of cake. The
engine is the main mass at the front of the airplane and it can react
the nose gear loads directly like a Questair Venture does. Also very
similar to a Bonanza.

Paul, beautiful piece of work explaining the engine mount details.

Thanks Milo

Kevin,
This is what your turbo installation will look like more or less.
You will need and inter cooler.
This is also why we moved the left side motor mount tubes outboard.
Gets them away from the turbo or muffler heat if installed.
I have a friend that is an excellent tig welder of aluminium if you
need anything done. The intakes plenum shown in the pictures was done by
him.
