Hi Andrew,
I run methanol, and my oil temp never gets real hot.
In fact I dont even hav a temp guage,
but on the dyno, it "seemed" hot, but the temp gun he had said 70 degrees sump temp.

A lot of guys that run petrol based fuel run electric fans or tow back from each run.
Some just run a 4 or 5" 'dry sump size' pulley,
and an oil cooler will help,
but I think that would be just one more thing to go wrong.
...especially in Tassie where it is generally cool weather!

I always use 100 dgrees C as a turning point for oil temp.
Most oils can handle much more,
but I would imagine power goes down around that point,
and VW said the mag cases deteriorate after about 115 degrees.
