I like the idea and prefer the advice of one who has used them over number crunchers who haven't. No offence to those, and while I can appreciate your math, I prefer real world data. So to put an end to this debate I decided to try one and find out for myself. I will report all results fairly and accurately. My install has the mechanical water pump removed although this isn't necessary, but it saves 10 lbs. However I am prepared to reinstall it should this be necessary. I have great confidence that it will work, but I'm not willing to die to prove it either. The pump only took 6 days to be delivered from Australia. It looks to be well made, a good design & it's lightweight. I've wired in the controller already. I did make a modification to the controller, by removing the internal trim pot and wiring in a small dash mounted trim pot. This will allow me to make fine adjustments of the engine temp while in flight. A little colder --- a little more power (not that I don't already have enough) and a little hotter --- a little more fuel economy. It comes with removable mounting flanges and adapters from 1.25" up to 2" hose. But since I'm using 1" hose I made a couple of mounting flanges from aluminium. Easy to make. just used a 2.5" hole saw to cut a flange from .25" aluminium plate, then TIG weld on a 1.75" piece of 3/4 aluminium pipe (1"OD)for a nipple, then true it up on a lathe & cut in hose barbs on the nipple. Took about an hour to make 2 of them. They look good. I will post pics of the installation soon. Test data won't be for a few months yet. A big Thanks to Leon who was good enough to supply it to me.
