Yeah it did seem rather personal, didnt it

FWIW i think these are pretty cool, it would seem that a lot of work has gone into them.
I would really love to see some proper data on their cooling effect, perhaps some testing could be done on the skp dyno

Data on the bench can be organized …
Here is some wheels on the ground Metr data. Rough pavement hilly terrain. Two different routes trying to keep the same speeds.

To establish a baseline temperature difference between the motors, start with a run without the HXHD installed. Mid-ride, install the HXHD on one motor and continue. In the logs, separate the graph lines to display individual component stats like the temperature of each motor.
Tap this to open a window displaying all parameters.
Tap a parameter to hide it from the graph. Tap the arrow to split the graph and display each recorded side separately.

Thats almost what i did. The time stamps show one hour of cooling between each run, and the temps are actually warmer when starting with HXHD in both cases.
One motor on, one off is not the right way because my temps often vary between motors. I ride heavy on the toe side so that motor works harder is always warmer.
Without HXHD
About an hour of cooling, warmer start temps lower average and lower max.

Again over an hour of cooling, motor start temp is always warmer. Average and max is lower.

They function or i would not sell them. I will also offer discount if others want to do this kind of testing.
