Basically, there might be a "sweet spot" of efficiency on the compressor map for the 370Z but it's going to be very different for an engine like a Charger SRT-8 however you can still use the same blower for each application.

One of the great things about the Vortech V3 supercharger is that it is a very efficient blower at over 70% efficiency.
