[S4to335]

The tracks I have been on have some very high speed sections...maybe conducive to cooling...I think sitting behind someone on course may affect cooling too. In the end..its a mixture of a bunch of factors as one might think. At Thunderhill I hit 125 in main straight...115 in back straight..and 110 between turn #9 and #10....and maybe 105 between turn #8 and #9. That was the track that I got 280 degree temps with...and the temps were at 70-72 degrees tops. This was with OEM oil. At Sears Point this past weekend there were only two maybe three places that I went over 100...and the temps were only in the 255 range ..with one anomaly being a session when I hit 270 degrees (1 out of 9 sessions)...AND I was going harder at Sears Point than I was at Thunderhill. I really think that 10w60 BMW Motorsport oil contributed to lower temps.
