Why is no one using the Track Dog Racing rotrex kit?

Getting the belt tensioned right seems to be almost an art. I'm in the middle of that 'art' right now on a kit I installed a little over a month ago. It's a nice kit, on the whole. As others have said, the instruction book provided with it is very nice. There's been a little more futzing around and finagling with this kit than I ever had putting an HKS centrifugal S/C on my BRZ. It just worked, first time, right out of the box. But, the kit on my '02, is getting better, incrementally. Teething issues, I guess.

True. There's a manual tensioner that has to be set. For the NB, you set it to 6 mm belt deflection at 20 lbs pressure...approximately. I say approximately, because good luck getting any sort of tension tester in there to check your work. I've been using the old Honda method of: twist the belt and see if it will 'just' twist 90 degrees, and if it will, you're good. If it twists further, it's too loose, if it won't twist 90 degrees, it's too tight.
The real fun is in getting your hands on the TDR-recommended Gates Green Stripe K040520 belts. Gates, in their infinite 'wisdom?' gave both the basic, cheapo belt and the Green Stripe the same part #. None of the local parts stores here can get them. The one that came from eBay, with a rubber band wrapped around it, looked like it had been hanging at the back of a bus warehouse on a nail for ten years.
I threw caution to the wind this past weekend and bought the Continental-brand equivalent. If appearances are anything, it looks to be a super nice belt. I installed it, tensioned it, idled the car for a few minutes, then re-checked tension. Took it for a drive, no belt explosion and what's more no CEL so far (from another un-belt-related issue).

I can get you a part number on what works for me. I use the 75mm pulley so I couldn't use the recommended/included pulley. I think it is the gates k040500 belt but I will double check when I get home. I think you can get what is known as their "RPM" line of belts that stretch less and should provide more tension and are supposed to be better for supercharger applications.
