Paul,
  Perhaps of interest to group........This has been covered in the past by you but here is a handy
pdf on the subject..........Shows in use on an air-cooled engine but will work for our liquid cooled
radiator systems also..........

 You can quantify your baffle and cowl (or Radiator) effectiveness with a home-made manometer,
as detailed here:

No Sh((*& ....:-)

I have been using manometers like this for 60 years.

There is a lot in my book "How to Cool Your Wankel" about it'

In the last 17 years there are 100's of email  messages about it.
