260 is an exception and not the norm. But I still do not like seeing that on the gauge. In the heat of the summer, cruising on the highway, I run 220-240. Get into boost and 260 is easily achieved. Depending on the ambient air temperatures and humidity, sometimes temperatures come back down to a reasonable level, sometimes they don't.

260 happens with hard driving combined with ambient air temperatures as low as 80 degrees though. I am confident that the SPAL fan will cure the problem.

I saw 260 last week and it was 78 degrees after some spirited, high speed driving.
