as to temperature
I run my lil 367 at 205 to 207,by IR gun, all the time, and on purpose. The hi-flo stat is rated at 195, and the clutch-fan keeps her right at 205/207.. And she went 93 in the Eighth at that, with a lil 230*cam. It don't matter what the ambient is or how hard the engine is working, in-traffic or not,... 205 to 207.
But, I run fresh cold air into the 750DP.
