Don,

   I had no idea that you were that far along..  90% done, 90% to

   Which scoop did you get?

   I can't emphasis enough the importance of radiator design.  As I

mentioned, I'm on my 4th setup and in each case I was pretty sure THAT

setup would do the job.  In each case, they worked, but not great.

suggestion is go for over-kill.AC evaporators worked, but not well

for fast flowing air.  I would think the same would apply for heater

The Motorcycle rads sound interesting but 2 would be a minimum.  3

better.  Series is fine but watch the restrictions what with the 1"

connections.  Don't put them in parallel.  In theory parallel is best

in practice, the coolant takes the path of least resistance and tends

favor one rad over the other.  You've got it right, for multi rads in
series, the flow should be, hot coolant out of the engine and into the

rad, moving forward through the rads until exiting the front rad.  You

have too much money or too much cooling.

   I'm planning on a cowl flap on the trailing edge of the scoop a la

You may want to consider the same.

   Keep up the good work and keep me posted.  I'll do the same.

Neil

Hi Neil
Many thanks for the info and open invitation to ask your ear off.
I got my A&A scoop yesterday and have been busy trying to match rads

it. When I phoned they said it was 9x24" but they had measured the
box--duh. Anyway it has led to a number of interesting discoveries.
--the heater cores used on GM trucks are now all alu (most have

tanks)
--motorcycle rads are all alu and many of the larger Susuki bikes,
750-1100cc, rads are crossflow measuring ~8"x~17". Fits rather nicely
with my 8 1/2 x 17 1/2 scoop. I'm actually going to use two rads I

I'll set them up in series feeding the rear one first In my case I'm
going to run alu lines on the inside of the cockpit to just aft of the
seatback at elbow height. It sounds odd but I sat with it today and it
works. Insulation will be an important item of course.
I'm still leaving the option of a heater core in the right cowl to use
as cabin heat or dump extra heat ( or to supplement oil cooling)
Wings are on, except for one flap I've left to make working on the
cooling easier, all electrics are up and running--getting close!
Will keep you posted
Don
