I am looking for 160 as the oil temp max. In traffic and the general track temps near the end of a race may make this a wish rather than a fact. We are in dirty, scalding hot air rather than the cool pretty stuff up high. It takes three down here.

That looks to me like a lot of heat exchanger.  Do you know you need that much?  What oil temp do you maintain at high steady-state power levels?
