Oil temps: 335 comparitive observation.

Search for ARC cool fins -- they use a heat conductive adhesive as well, and while simple and kinda "ghetto" seeming, it does help pull heat away.

I have 2-3 all over the underside of the oil pan and another couple on the dif. On the dyno, oil temps drop down faster between pulls with them as well.

In normal somewhat spirited driving in FL i typically see temps around 200* - 205* F tops, and logged around 207* F on Cipher. In prolonged drives in the heat -- 220* tops. I've never seen it go past that after the fins were added, whereas before it might creep ad high as 235* -- still not hot enough to really worry, but the fins are very cheap and do actually work as claimed.

But, thermodynamics predicts that the extra surface area of metal fins will extract and disperse heat, and lo and behold, they do.

For the ARC fins, which are, after all, only stuck on, the key is surely the heat conductive adhesive -- any old regular 3M trim adhesive tape would presumably not work very well.

You can definitely fit at least two on the diff -- a cheap-o alternative to the Nismo finned cover. Not as flashy, but same principal
