I got to help with a repurposing a building several years ago for a DAYCO Belt Research facility, it was a mini plant so to speak. Started out in the Mad Scientist offices, they messed with the cord material and rubber compounds then moved to the mini plant and manufactured them. Then they went into testing, first they went to sound testing in a very quiet special room, second was chambers that sprayed Arabian dust particles on the belt W/ tensioners while running, Then to the water brake area, where they could simulate the loads of several different HP engines and how long the belts would run before breaking, of course recording data the whole process. Before going into the real production. Honda needs to test and gather data on there own, a simple dust test simulation would have been fantastic.
