Left Side Oil Feed/Return Lines?

[brazen]

Hey all,

I'm a bit of a novice when it comes to racing Porsche knowledge, and I noticed an interesting detail I had not seen before..

Plus, this question gives me a chance to post some IROC pictures!




Images are a bit small, but I can see what are the typical oil lines for a 911, on both sides of the car? Are these typical on racing models, or just an IROC thing, or what?
As far as I know, these use a single external oil cooler up front, so why would it need all this extra plumbing?

Cheers.

Not seeing it here.

I doubt that the Fittipaldi car is THE original. The other lines could be A/C or a custom trans cooler.

Didn't see them on the real one at Rothsport in September.

Well, 'tis:

Trans cooler makes sense, but I was under the impression that competition 915s used a mid-mounted one off the gearbox.
So the question remains .. I feel I've seen it on other racing cars, but can't remember where.

Here's one line on a 934, maybe a different setup?

The "oil line" on the bottom picture is an A/C line which is held on by single clamps
