That IS good news Al, I've been waiting for more results from your coolers. I think they are still a great idea, and I wondering if it wouldn't be possible to plumb in some small fan's for cooling during ground running? When I was helping my father re-built a VW bug, we put these niffty little fans in the heating system to increase the airflow, they were in a 2 1/2" PVC pipe [ I think..], they came w/ mounts to mount them down etc, all you'd need to do is plumb them [ I know.. into a closed wing..] so that they dump air into the cooler plenum and give you some level of cooling? They can flow something like 300CFM. Getting all the air to flow through the cooler might take a bit more work, but it would be a periminant solution, you could also tie the system to the oil temp and squatch switch.. they would become automatic..  if you wanted to do a temp. fix, you could just tape them to a scat hose which is taped over the opening into the cooler.. this might keep your temps d own while you ground run at least?  There's always Tracy's water spray idea.. the only neg. on this I can think of.. is making sure you have water in the system before each flight/run.
