Which is also why Sam said the stage 2 does not need a smaller pulley as it did not show any increase in power, similar with the stage 1.

It has more to do with the supercharger being maxed out ,and to much over lap. The stage 2 flows 11% more than the stage 1, if you compare the two dyno charts that Sam posted it adds up to that.

That is what I am saying, the efficiency range of the stage 1 is at its max. So trying to run a higher PSI or a lower PSI, on stage 2, is not a worthwhile test.

It can be done with the Stage 2 unit it would just need to have a bigger pulley to slow the unit down.

I do see you point now however, with both units using the same pulley now it doesnt make sense.
