Hi, I was just curious to see if anyone has any info on the design of water pumps that are used as power absorbers on dynos. My understanding is that it is basically a torque converter with a variable load valve that dumps more water on the stator(?) to create load. This is the major piece I haven't solved yet. You can buy all sorts of torque sensors and lots of software, but a reliable and practical method of creating load is my problem, without spending 6-25 K on someones dyno. On small engines a large brake rotor with caliper works and I even thought of an oil cooled submerged rotor (like a wet clutch) but that seems to high maint. I have thought of using a large generator as a load device with a variable load panel but it seems that it would self destruct at higher rpm. What I quess I am looking for is a water turbine to run backwards. Thank you for any help, Tim
