Kelly said 260 was max on a hard run, 210 220 @ cruise

Near 1000hp , 190* cruise , 240ish wot.
13 plate bellhousing coolers , Lake Michigan water.
Oil might be okay at 280* but what are the bearings and such seeing? Like Griff said it depends on where that temp reading is being taken.. before or after the cooler .

after a few runs this past weekend under 10lbs of boost i never saw a degree over 235.

My Starboard always runs hotter.(30*). anyone else have the same issue, drives my OCD crazy

i use this to great success. Always works and there is real data supporting it.


Do your research, the science and dyno proven results with lower oil temps too.

my starboard is the same - consistently 20* hotter across the entire range. It bothers me enough that i might put mismatched sized coolers on it this winter. It annoys me......
