it picked up about 8 or so cfm, maybe 12
I'll have to check notes. But yes it helped .550 and up. May have had an impact on the three or 400 number that I can't remember.
I think this may have been one of the heads with the core shift because the short turn is not kicked out very far at all on the dog Lakes side of the bowl. One thing though is it likes to be pushed out round as opposed to be pushed out and then angled over.. and all I can do is directly relate that to speed of wide stream vs narrow faster steam... I can't forget that's connected directly to the current port shape
