The spec I see is for the upper pulley on the R is 74.5mm, which is 2.93". Stock is 3.15". Looking at both engines, the FEAD looks to be the same, so it likely will fit. Anyone do this yet?

Just buy the Hellraiser clutched 2.8 or 2.7 it’s a bit cheaper then oem. I’m running the 2.7 making 1k hp.

I think the options are 2.9 and 2.7, but I also heard they discontinued them. There may still be units in stock somewhere. I've been running clutchless pulleys since my first TVS and the two that preceded it. When I go to upgrade my 2021, it will be clutchless too. You can buy 3 pulley rings and the hub for what you pay for the Hell Raiser pulley. You can have your supercharger ported for the cost of the Ford piece. I just see it as one less component to break.
