Rick,

For what it's worth, out Aurora IRL installation guide (GM performance)
specified Mobil 1 15W-50 synthetic only at 80 psi. Maximum recommended water
temp of 195 F and oil target temp of 203 F with a max of 230 degrees. Heat
rejection at peak power was 54 hp to the oil; 150 hp to the water at those
guide lines.

Those guys frightened me so we tried to do the right thing.

NEVER made a run with oil temp at least 150 deg f and at 180 H20 temp.  The
N/A motor now on methanol has a heat exchanger inside the oil tank with
coolant flowing thru it, and I preheat both lube and coolant.  On one of my
learning visits to the salt, I watched somebody destroy a Carillio rod when he
made a "cold" pass.

clearances that like it once everything was warmed up.  I flowed lots of oil
at 60 to 70 pounds pressure.

have more resources than all of us combined. AND the run only 1 lap
qualifying.  I would look at Indy car qualifying at Indy for better data.
Problem is getting data.
