I recognize that what I can visualize in my head and/or comprehend may not be put into text/verbiage that another person may understand. Nothing against the other person as it has more to do with how I explain things. Perfect case is yesterday when Dave.0 talks about meth not helping the supercharger heat. I looked at that and my head went right to the downstream air flow. The 19% pulley would be creating more boost at low engine rpms as the supercharger is spinning 19% faster than stock. At low levels of engine rpm the boost is more efficient relative to heat generation. As the rpm level increases the supercharger does not create boost in the same fashion as it is in the realm where "squeezing air together" has become so difficult for it that efficiency drops. In my case where I am not concerned about triple digit track speeds but rather low end torque on twisties, it appears the 19% will provide what I am looking for. At approximately 5,800 engine rpms the 19% will be at the same supercharger rpm as the Stock S engine. Past this 5,800 engine rpm point, my supercharger will not be producing boost as efficient but so what? We are talking about a matter of a few seconds for the engine to go from 5,800 to redline. Hence the MI that would appear to help mitigate the heat created by the inefficiency.
