Here is the article from my last round of testing: http://www.hotrod.com/articles/dyno-tested-vacuum-pump-help-engine-make-power/

Peak power with the vacuum pump and the Wilson ported intake was 775 hp. That is running unleaded premium with out of box Trick Flow 270 heads. I'm sure that more compression would make more power but we're getting close to the limits of a stock block so no reason to turn up the wick anymore.
