Agreed the super charger would be a constant volume but will change in frequency with rpm...........
(except multi stage superchargers which are not "sound" modelled in AH so when it is switched in the engine model to the 2nd stage we do not hear it)
AS `said I agree the KISS approach would be to have a fixed back ground mech noise that varies in frequency with rpm then an exhaust note that varies in frequency with rpm and volume with manifold pressure.
Splutter could be used during the start up .wav and left there.
