To George ( down under) and others interested in cog-belt PRSUs:

(Bernie: "George, you're upside down!" George: "No, no, YOU'RE upside down!! I can see perfectly well that I and other people, and houses, and telephone poles, and dogs are upright! SO THERE!!"

Here endeth the silly stuff.   George, you wrote "Ask about weight, type of torsional vibration DAMPER, density of Damper, tracking adjustment, density of engine mount rubbers, and HP limits". Which rotary model should they focus on, like the 13B, 13B Turbo, the Renesis, 20B as having the potentially greatest demand? Same for potential demand for"normal vertical" engine orientation or "Plugs Up".  They will have to expect a potential market for the effort in designing and making one or maybe 2 versions of a belt PSRU for the Rotary.

You other guys, please join in with questions that should be asked, or other strategy points. I don't want to make this inquiry without ducks aligned. Have you ever made a technical inquiry and you were ignored? It's happened to me, and I was angry and frustrated, worst of all, I was not being taken seriously and I did not get the needed information.

Let's hear from you. For those that have missed the beginning of this, it's about the first Cog Belt PSRU that I have seen with a torsional vibration damper instead of the driver pulley mounted straight on the flywheel. George found them in Brazil and sent the web addresses to me. The site is in Portugese only (except the numbers are in English - yuck yuck). We want to know a little more about their PSRU, and if they could be interested in trying out for a Rotary PSRU. We're basically asking them to spend a lot of money, engage in a lot of effort and sweat, and it's all a big risk for them:

Thanks, Bernie.
