Sorry for the late reply, had no idea anyone responded to this post.
The tensioner is from Ripatuned, link below, and the catch can is from Billet Technologies, link below. Billet Technologies will take forever to deliver, it was months for me, but the product is great. If you could get them to make the hoses just a bit longer it would work better. They are not designed to work together, but with the right pulley size and belt length there is just enough room to make it work.
The rpm belt is amazing. Put about 300 miles on it so far, no issues, perfect reliable 19 psi of boost, no slip, no squeal, 100% recommend this belt. It took gates two months to make my belt but worth it. I bought it directly from them on Amazon, it was the only place that had the part number/length I needed.
**NEW PRODUCT ALERT** Ripatuned Infinitely adjustable idler pulley, no need to remove the pulley to move its location any longer... no more in between belt sizes needed. Just loosen the bolt... slide the pulley EXACTLY where you want it for optimal tension and lock it down. Problem solved. We...
Dodge Charger and Dodge Challenger Hellcat Catch Can manufactured by Billet Technology.
The belt part number I am using is: K100586RPM or 10PK1488, 1-3/8" x 59-1/4"
This fits with a Ripatune idler, Incognito lower pulley, and a 2.57" upper pulley. My advice is to use the fleetrunner belts as guides to get the right part number, then order the RPM and wait wait and wait some more. Make sure the belt tensioner is nearly all the way loose, this belt does not stretch and does not need the tension like the green belts do.
I will admit my setup is not really ideal for a daily driver, especially the horrible mileage on E85. But it's only driven 50-100 miles per month, and it's too fun to go backward. I have my eye on the Hellion Twin Turbo kit as a next step. If so, all the pulleys come off and the supercharger speed will go back to stock. Its going to take a while to save for that kit but I think it will be well worth it.
