You should probably tell all the Pro Stock guys how worthless their dyno's are. And their spintrons. And the flow benches they use.

A dyno and a torque wrench are the same thing. You can make them lie. Why bash the tool? I could tell a guy + or - 3 MPH of what his car should run with my dyno numbers. ET is hook.

I didn't say dynos are worthless, I said it irritates me when they are used as a "sales tool" this very thread is a good example, engine builder brags in a open forum that he made the most power to date with procomp heads...but once installed in a dedicated race car, it ran 122 MPH... that my freind, sure as hell aint close to no 670 horsepower.
