And I'm back.
I hope everyone had a good holiday. And that's where my testing time went last week. Here's hoping I manage to get some time to do testing this weekend. At least I don't have anything in specific planned.
I just got off the phone with Boca. (yes, the bearing company.) What's the most common size .. lets say wheelbearing. I'm going to get a few samples from them for testing, and for "treatment" testing.

A shock dyno would be the easiest thing to do (one like the CSI dyno, a rotary one), I have all the parts to do it here at home. Also, as I said before using a telemetry system one could use his own car as a complete dyno (my intention), having ~on track~ information. As we speak I have the G-forces and temperature sensors part done and to be more precise I will add a humidity sensor and I have a set of linear potentiometers to measure shock stroke I intend to add later. Oh and GPS off course.
Shock travel is not important to measure, you need to know how stable the chassis is, a G-force sensor on all corners of the chassis or a short distance range sensor (optical or ultrasonic) to measure the chassis height is better.

With an onroad car and an aluminium chassis you can even think of simple temp sensors on the front and rear to see if the chassis is touching the ground.
But your project looks a bit like mine

Reading through this topic there are some neat thoughts....

A detail of lubes, who makes them, and what's good about them.

Wow, time goes fast. Personal issues are keeping me away from testing so I've been reading as much as I can. The most important thing there could be right now is tire testing, as knowing how much load, temperature and alignment they like. For that I've been modifying my arduino telemetry system to take temperature, humidity and G force. Still have to do a spreadsheet to organize collected data.

Anyone know how to do a carpet plot of TC tires.

Dude, that's awesome. CAre to share some specs on it?
I can see industrial pillow block bearings, black PVC and endcaps, and arduino doing something.
How are you picking up rpm? Do you have any weight in the tubes? How are you accounting for the pillow block resistance?
