Cooling a 2.7l Type 4 easier/harder/same as a 2.7L flat six? Options

[Tdskip]

Only a slightly theoretical question at this point – is there anything inherently different, or different in practice, between the oil cooling set up needed to keep a 2.7 L flat six cool versus the same displacement 2.7 L big Type 4?

It would seem like the flat six would have smaller displacement per cylinder and that might have less heat and more cooling fin surface area?

Kind of an interesting topic I think / hope.

Happy Friday.

Neat, thanks Rich.

So is cooling the cylinders the bigger issue here than keeping oil cool?

It's really not an either or thing. Cooling an engine is a sytems engineering problem.

The best example I can give is back in my college days participating in Formula SAE (look up details if interested) it was common to yank an engine from a Honda CBR600. Water cooled.

The engine was usually shoe horned in right behind the driver seat and had zero airflow.

Even with zero engine modifications and more radiator area than stock, the engines had a tendency to overheat, especially under load. Why?

Turns out that although the engines are water cooled, when they are used in a motorcycle (even with a fairing), they still get alot of air cooling of the aluminum block, head, and transmission housings. Sticking it behind the seat with zero airflow had unforseen implications becuase we didn't look at it as a system.
