Regarding the "low end torque increase" A superchargers boost curve is 100% dependent on the RPM of the supercharger. So a pulley change would cause the boost to build quicker. The other side of this is that in doing so you could potentially over spin the supercharger by the cars redline. For those looking for that low end, an optional pulley could be made. Just might have to lower your rev limit a bit. Of course this is all speculation until we see what the base numbers are.
