Easiest way to test cooling ducts?

Lots of cars available with small radiators. Look at 1 litre and sub-1 litre cars. If they are still too big, look at water-cooled motorcycles.

Last I did this, the radiator shop I used could make a unit pretty much any height I wanted from my top and bottom caps, AND, could cut down the width also. Be advised it will be very pricey and you need a sympathetic owner of the shop that doesn't mind paid experimentation and a bit of extra time for parts shipment.

1) my comments will no doubt remain a mystery until after you've completed the degree in mechanical engineering.
2) I've been around car modification since junior high/ middle school
3) I've been involved in motocross motorcycle modification
4) TT Scrambles motorcycle modification
5) I've been party to a 289 cu in V-8 swap for an inline-six, with a Ford Econoline van.
6) I've been party to a Chevrolet 265-cu in V-8, Hydramatic transmission swap into a Volvo
7) I've been party to a Buick aluminum V-6 and Turbo-Hydramatic swap into an MGB autocross race car
8) I've been party to a Ford V-8 and transmission swap into an Austin-Healey
9) I've been party to a Subaru engine swap into a Volkswagen Vanagon Westfalia Wasserboxer
10) cooling system 'engineering' was always a collaborative enterprise. Many parents participating in the projects were quite literally 'rocket scientists'

I am glad you have been to so many parties. But that's not what I asked, is it?

Again:

You've never done an engine swap and chosen an appropriate radiator?

The advice you gave in the second post in this thread was either chosen to be deliberately confusing or just reflected your ignorance of practical car modification - can only be one or the other.

1) I believe I explained my experience quite well.
2) a hypothetical was given. Without additional information, no meaningful contribution can be made. I don't live in a binary universe. There exists a great deal beyond one or another.
3) lose the 'deliberate' type of language. It's wrong, it's uncivil, it's ungentlemanly, and completely unacceptable.

Many of your posts here on car aerodynamics are wrong, misleading or deceptive. Either it's deliberate or you're just confused about the subject.

I accept the fact that this truly is your experience.
The issue for me is that, when these comments are made, they appear to come from a position of ignorance.
I've never seen you defend any of these assertions numerically, which is a scientific requirement to prove your premise.
My experience is that you do not comprehend:
* separation
* the 'template'
* lift
* drag
* road testing
* thermodynamics
* wind tunnels
------------------------------------------------------------------------------------
Dropping names and titles is not indicative of comprehension of the materials.
Your sources DO appear to have a command of the material, however, it doesn't necessarily translate into YOUR narrative.
We've discussed the 'perspicacity' issue. Donald Rumsfeld famously addressed the situation with his ' known-knowns', 'known-unknowns', and ' unknown - unknowns'. Often, my experience of your posts reflects the latter of the three examples. And as Carl Sagan and others have commented, some , although possessing the potential for critical thinking, will never develop the ability for critical thinking. Which if true, would always leave us at an irreversible impasse. You may never understand me, even when science is with me. Your rigid belief system will always throw up a boundary to counterfactual evidence. Conformation bias. No cure.
If this is the environment in which you 'communicate' with your network of 'experts', then we have to take everything you say with a grain of salt. You're liable to get it 'wrong.'

The professional aerodynamicists that I mention:

1. Are available to me when I have questions.

2. Check the accuracy of what I write in my books.

This - and my own measurements and research - gives me the confidence to state that much of what you write here is wrong, deceptive or misleading.

This list pretty much sums up where you make the greatest errors:
