Going riding that hot,+35 you might consider a pacemaker yourself.. No need for big coolers,just remove that fan for trackdays. Better airflow will result in lower engine temperatures.
That's how it is in Spain end of May. The 3 days were 32, 32 & 35C, Unpleasant. With my race exhaust the bike gets noticeablely hotter than with a standard exhaust, so probably negates any improvements that may come about due to improved airflow. For me, running without a fan, not a good idea as the bike needs careful management before and after going on track. Fine if I keep on top of it but more to think about. Without a fan, true, once on track engine temp stayed a constant 95C. But I chose to use a race rad/oil cooler to drop that to 85C as I think prolonged heat exposure to engine internals not the best idea - I've snapped a con rod on a Panigale before with painful consequences. So anything that can be done to improve reliability is in my view worth investing in. So. based on personal experience, I'd stop short of making any statement dismissing the need for better cooling. Still, if it works for you....
Dano, a quick question, did you have the AIS still running, or the smog plates fitted? looking a the spare engine i bought for parts, there is also a hairline crack in the the cases, and i am lead to believe this is a common product of overheating. I, like yourself have the Evo 3 system and the fan removed, and my concern is also the high Oil temperature generated by the lack of direct cooling ( as we have only a heat exchanger as standard) so any improvement on the temperature created is a win win. the AIS allows air to bleed into the Exhaust to improve post combustion burn and also warm up the Cats quicker, but the byproduct of this is going to be extra heat build up in the manifold area, so i am interested to hear if this helps matters in regards to temperature.. i have a kit sat at home and will look at measuring the Manifold heat trend on a few rides and then with the smog plates fitted, to see if there is any change
