ATI Super Damper
 

I've been looking and looking and I am coming up with nothing.

I just installed a ATI Super Damper on my '14 Zl1, with a 10% (8.66") overdrive Supercharger pulley. I already have a 2.55" supercharger pulley installed, with a 100mm idler pulley. From all counts that I could find, I would need a K080670HD belt, so that's the one I order. Compared to the stock belt, it's about the same size. I go to install the belt, and it's too short. I've already sent it back and ordered a K080690HD belt. I'm hoping that this does not drag out too long, and this one fits. But in the meantime I'm trying to find what size belt others are running, with the 10% overdrive pulley.

Update:

K080690HD is too long. Gonna try K080680HD next.

Update:

The K080680HD worked. Although, I went with the Continental Elite instead of the green belt. I do however have an unneeded K080690HD green belt. Hit me up if you need one, I'll give you a killer deal.
