If you open the throttle during stationary ground operation = you should expect it to overheat.  Stationary engine dynamometers = have HUGE radiators/coolers with ducted fans.

Steve,  I can run full noise on the ground with no = heating problems, but then I do have 900 cub inches of cooling. =  600 for water and 300 for oil.  I did insist that PWR make a = rad that WILL cool.  It does regardless of OAT.

Hi Guys

So what are your experiences of = running on the ground.
Do = your setups cool on the ground at any throttle setting?

I=E2=80=99m still not in a = position to open the throttle as Im in a garage at home.
After start and running at about 1500RPM (engine) with = an OAT 90+
temps slowly rise till i shut it = down before it gets past 210F.
This = takes probably 20 Minutes.

What do you guys see on the ground in your various = climates and cooling setups?
