You guys need to read the article..

we are not talking about overspinning the blower. We are talking about spinning at its efficient rpm which usually is a good bit higher boost than most people would want on the street or on the engines.

Take my old D-1 as an example. I had it pullied for 14psi but it actually was most efficient at a much higher impeller rpm than what I was spinning it at.
