Way too go! (besides, The truck axle would be well able to cope with it =
just through the engineering for torqu, not just horses).. nice idea =
about the pump, but dont you get trouble from possably stalling the pump =
system, or pushing the water into cavitation by restricting its flow??

how much kinetic/potenetial energy will these things dispose of in a =

laden dump truck going down a reasonably long hill??? Might not run
continuous, but I'll bet it would cope with 10 - 15 min run.

I have thought about this too. My idea was to use a large water pump to =
load
the engine. I would throttle the discharge of the pump to load the =
engine
and measure the resulting torque. Since I work at a 760 mega watt power
plant and have seen the effects of catastrophic power train failures, =
I'm
not sure if I would have the nerve to go near a home built dyno loaded =
up
with 300 hp @ 6,000rpm.  But, you only live once so..."it's better to =
burn
out than fade away....'
