We all know that turbos like diff gears with longer legs so they have morr load to build boost but is this the same for supercharger setups?

I thought that supercharger boost is fixed for engine revs. Nothing to do with diff gears and engine load?

But im confused as even n/a cars produce more power in higher gears (more load)

Im looking at fitting a positive displacement blower to a ba xr8 with 4.11 gears (6spd man) and not sure if its the best diff ratio for it

I'll put my 2c in...
I have found blowers generally have lower ratio's..
Higher numerically.. Yes 3.7 to 4.4 gears depending on tyre
diameter...Especially with centrifugal blowers..
