Hi Bruce,
That is defs not the pump I picked up.... I tagged the make to the closest wreck it was lying next to... I will give him a shout when I get a chance and find out what it is out of....
Glort: I am not to wild about spinning blades on the flywheel, even blunt ones, but i took a bit of a closer look at the breeze coming off the wheels (stover) of TM1 - it is not a stiff blow, more of a forced circulation... Probably enough to hold TM1's temp at about 3/4 load(but difficult to judge accurately because of the low velocity/high area of circulation) - Interestingly, with the little 150mm fan running(out of a scrapped microwave), at 1/2 load the main fan(250mm out of a blower coil on a refrig unit) hardly comes on at all, and then only for about a minute or 2 at a time. I think that the heatex I put in is drawing a lot more heat off than I previously anticipated.... Come to think of it, I stuck a screwdriver into my hand while I was fitting the heatex, so it got the anointment it required for flawless operation....
Mike: I started off with a large tank a la lister original spec, but found it way too cumbersome for a movable unit, hence why I moved to radiator almost initially. A further plus in the long run has been ease of fitting other dangly bits to the cooling system, such as heatex/temp control etc.... I have not looked back!.. In fact, if I suddenly lucked on a full system with a resevoir, I dont think I would even run it with the resevoir to test - I would install a radiator immediately. (Well almost immediately, I would definitely do a balance job first...) The only problems I have had with the durability side of my design have been vibration induced, bolts and tie down chains breaking, radiator core leaks, alternator brush sparking, cables chafing etc....
Bruce, if you have a little 12v available, try a computer style muffin fan or two, in hindsight, looking at the air moved by the small fan on my unit, it equates to about 2x100mm PC fans' worth... Just a thought...
