Well now that you guys say that, it makes since. I guess the balance of
speed of the water going through the complete system and how it is
controlled is a valid point. I know the Comp Manuals we have are based on

engine said that it has been years since anyone has asked him to lighten up
a connecting rod or shot peen one.
