Jerry Magnuson likes higher BRPM's with the newer designs (especially TVS). With my 8" crank pulley and 2.8 blower pulley shifting at 6500 rpm I am looking at 18500 BRPM. I just have to take it one step at a time so I don't really have any predictions, just hoping for the best..
Does Eaton have a recomended max speed for the 122? I would guess that the issue wouldn't much be laying over as far as cfm production, just a concern of heat production like the 122. Of course though like you said, there aren't many out there yet and we'll soon find out.

spent the morning running around.....picked up flexplate from the balance shop, dropped off the drive shafts for a balance check, & picked up some Evans coolant from a neat little 1900-1920 Restoration shop.
