No charge cooling is a big minus.

It had a liquid aftercooler.

OK, trying to keep up here but struggling.

So which is the top option between the V-1710-E27 and the V-1710-H?

And photos would help please...

Do you need a hammer or a screwdriver?
A power recovery turbine setup, like the E27, is best for raw power at medium and low altitudes as there is no need to throttle the turbine. A pure turbo-supercharged engine, like the V1710-H, is a mechanicaly simpler and lighter system that offers better fuel efficiency at a slight cost in maximum power
