So the 'turning vanes' are to make sure inlet velocity is converted to pressure?
Or do they spread out the airflow so it flows thru the whole cooler, not just one round spot in the middle?

If it 'almost cools' a 3 rotor, it should be fine on a 2 rotor. The radiator is still on the right side with an extreme wedge style diffuser. I found that I had to use a turning vane in it, to get even flow through the core. The turns are even more extreme with the oil cooler (much shorter diffuser), so I decided to include the turning vanes from the git-go (Southernism). Still a few more steps to go before I can check the flow, but I'll post a video of the flow once it's completed.
