How many cc's or how much HP before..., needing an external oil cooler in 914-6? Options

[horizontally-opposed]

Obviously, a 3.0-liter SC motor is gonna want an external oil cooler, but what about a 2.4E or S? Will an on-case cooler do the job, or is it iffy?

Also, who is using the right inner fender for the cooler spot on a /6? What size engine are you running and what temperature extremes have you seen?

Thanks!

what were your temps before mounting the cooler ?

The cooler was installed the same time as the engine, so I had no A/B comparisson.

I built a car for a customer, a Euro Carrera 3.0 that was built out to 3.2 with 9.5/1 pistons, and GE60 cams. I did the whole front cooler thing for that car with a custom steel front shroud. The car was used for autocross, DE, time trial, and on some trips. The owner told me he never ever saw over 200.

I know Dave at GPR has a Motronic 3.2 in his car, with no external oil cooler, and doesn't have any problems, but it is a street car.

If you are going to do track events, then I agree with JP. But if it's just autocross, then I'd opt for the rear quarter install. Main reason I went that way, is I used the car for trips and didn't want to loose any trunk space.

Bruce A. does say that much of the cooling you get in the factory set up with the hard brass lines, is inductive cooling from the lines. His favorite oil cooler is the 27 row brass unit, which is nothing like the "radiator" units most of us use.
