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. I 
had to put a thermostat in to get the water over 60 degrees.  I have too 
much cooling.  Neil.

Hi Guys

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

I’m 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?
