As far as I know, your typical engine dyno is water cooled. (And regulated 
by water level. (?))  200HP = 128,237 Kcal/hr and it takes 539 
kilo-calories to convert one kilogram of 100 degC water to 100 degC 
steam . 128,237/539 = 238 kg/hr, or about 65 gallons.

>From a previous post, someone said you can get a the heart of a dyno 
for less than $4K. Not quite out of the range of a DIY'er. Using a 
truck retarder for the load cell looks interesting too.

I liked the idea of using a pool for the heatsink. Too bad I live in 
Georgia and there isn't a pool nearby I can use. I do have a nice big lake 
just a couple of hundred yards from the house though...
