I am torn between a Keene bell blowzilla and a vortech s trim. I know the Keene bell is getting harder and harder to find and is also easier to install the guy who is offering it to me is asking 2000

now I have a vortech s trim with 2.82" inch pully. I already have it but it has a small chip in impeller about the width of a nickel. I don't know it that will affect performance or not.

Help mr please which should I go with. Should I sell the vortech with aftercooler and buy Keene bell or vis versa
