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. |

The 2.7L Type 4 is a wet sump but had a 914/6 style Front oil cooler set up .
I didn’t run Type 4 2.7L in anger a whole lot but with that set up it never really got hot, it had an oil pressure problem, but it wasn’t due to the oil getting overly warm. Sounds like the answer is “at least as much if not significantly more” cooling is required for a big Type 4. I’ve seen that some flat 6 2.7’s run trunk mounted cooler successfully, but let me be pushing it for the i’ve seen that some flat 62.7‘s run trunk mounted cooler successfully, but let me be pushing it for the Type 4. |
