We tested our Magnuson 2650s well past 26000 rpms, there are a few guys running or exceeding that 26000 rpm and boosting past 27 lbs. But when you get to those rpms you need to run the 10 rib as most have found past 25 lbs you start getting belt slip. Toohigh has a 10 rib setup with a much better tensioner then any on the market that I'm aware of and for sure better then Magnusons stock tensioner.
