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. |
I was under the impression that the 25R oil cooler was designed to be open to the direct air flow being forced in through the opening in the bumper at higher speeds. Just like the radiator has to in the path of the best air flow. Just my opinion... But I think if you relocate the oil cooler to in front of the radiator, you should probably see better results. I just don't see it getting the proper amount of air circulation through the coils hidden off to the side. Just like the radiator needs the air to cool off the coils... so des the oil cooler.
