Maybe, I just didn't notice? I will duplicate your description later today.
I agree, I think. It appears to me that my 90 will become more heated if I spend much time in the lower gears, like doing road work where 3rd & 2nd & 4th are used alot....specially if I slow down and cease playing and drive normally. At that point it appears that I heat soak for a good while till the cooling system calms down or catches up to the heat load that I just generated by my sophomoric behavior......it appears that the higher I go in the rev band, and the longer I stay higher in the revs, the more by-passing takes place in my 90's cooling system? It appears if I insist in living up past the 4k mark that after a good while the oil & coolant temps start to spike even if my velocity is at a good clip. I seem to get my best cooling performance when I can keep to about 2k or below in 5th or 6th with a constant speed. Maybe I have something malfunctioning?
