Trans Temps, What are people seeing? Options

[0396]

I'm no trans expert but majority of the solutions have been presented - such as: engine size, main topic..oil temp, proper back lash and pinion. As for a larger bearing to distribute the load, maybe some one has already thought of that. But if my memory I correct, there' s not enough metal between the bearings ( main shaft &pinion) for this.
To my knowledge, the 934 / 935 were eating up ring and pinion years ago until the race teams used Swepco trans fluid. I just had my spare 86 915 rebuilt by a Porsche race team. The tools to set the ring / pinion cost $6k...the tech asked me to use Swepco..I brought 201 and 210 to his shop and he used 210. His comment was, 210 is a heavy oil, but it will run cooler....this was in light to my question on my 80% locking Guard unit. Based on the pictures above, i would exam the gear sets closely- they most likely will have small bits of metal pressed into their face. This will cause an uneven mesh of the two gear sets....i've been down that path -(IMG:style_emoticons/default/sad.gif). Just my .02 cents

Ps..I opted for a new aftermarket side cover too

just another data point:

I took my cooler set up which normally runs a 3 inch flexible tubing to the cooler from an underbody aluminum scoop I had built....

Over last weekend, I disconnected the scoop and zip tied to the hose to the drivers side window roll bar. not protruding into the air stream but close to the edge of where the side window would be... so definitely close to the air stream, but no scoop nothing effective in the air stream

20degree F drop in trans oil temps
the highest I saw on a moderate day was 205 - 206F range
