Thanks Ottoguy for the explanation, as I said twice in my posts I'm not really that well informed on the procedure. Even though I understand the principle of how a turbo would work better on the high end, and the mechanical supercharger would take care of the bottom end, I wasn't sure how you would disengage the mechanical charger. But you cleared that up for me (after all, we've all see MAD MAX). Still, doesn't the turbo charged air entering the engine, do so, thru an alternative intake? I mean, if a "hair dryer" is blowing air into the same intake of a mechanical supercharger (that's not spinning) how would the "turbo charged" air ever get past the "stilled" impellers, and into the engine?
