Ernest, I thought the calculation for a test club was X section = 1/15th of length, means a 90mm square should be 1350mm or 54” in your language. mine is 90x1350mm calculated to absorb 190hp@2450rpm. do I have this wrong, or do you have a more up to date equation? only problem I can see with using a test club is needing supplemental air for the heat exchangers or very short runs.
I used the attached spreadsheet.
Nawh, you got it right. I left mine long for two reason
1) I wasn't sure of the length when I was cutting.
2) I'd rather have it absorbing more than necessary, and then sneak up on the proper length.
