You may want to check and see if this is the same process that was done for us last summer by Rick Miller at Extrude Hone in Irwin, PA. It was a new process he developed to produce max flow of 193 cfm on ther duratech UIM. This is more then a double or tripple hone. Not sure if they are doing it at both facilities or not. Better be safe then sorry.
