I absolutely love simple mods like this! the only issue I have with it is that it seems almost too loud overall. Most superchargers i find actually aren't very loud until the higher rpms. but nice work!
A simple yet pretty well done mod. It adds a nice scream to the supercharger for sure, though it does sound rather odd at really high speeds/high rpm... like when your upside down and just flooring it. All in all I really like it. Think you might do it for other engines?
It is really good, but a few things bother me. It is weirdly loud on idle. I really doubt any supercharger is so loud on idle. Secondly, the sound and pressure are not linear to RPM which is key feature of supercharger. Not sure if you are unable to do anything about that beacause it is for example based on turbocharger or something else, but keep that in mind.
