Hans;

 

I have a blower that I used for flow testing the radiators and oil cooler (see attached photos).  I got the blower for nothing at a heating/air conditioning shop – removed it from a discarded furnace.  You can also see it in use on my engine run video (go to http://members.cox.net/alg3/airplane.htm , and click on ‘engine run video’.

 

Setting up for testing in my driveway was one thing, at the airport is another.  There is nowhere to set up where I don’t have the risk of being in the way of one of my hangar neighbors if they want to get their planes out.  But the reality is that if I want to get some duration of run at something like steady state conditions, I’ll need to haul blower, fan, etc. to the airport and get the job done.  It may not take all that long, but after reviewing where things stand, I’ve decided to start over from the defaults, do a Mode 3 adjust, Mode 6 adjust, Mode 1 over the range, track mode as necessary, then an auto tune verification.

Now that I think about it, less power will do, maybe you can just rent one like this. Carpet cleaning shops use these.
