Just came back from a run on the beach with our club. I have no fan on the intercooler and had EGT's of 350deg on the bitumen at 100 to 110 on the way there and back. Dead slow on the beach through the sand for nearly and hour, never exceeded 400 deg and water temp was steady all day at 90 to 92 deg. Admittedly the EGTs were up dead slow in the sand, but I don't see it as an issue. BTW the ambient temp was mid to high 30's.
