It at least will void the warranty on the motor and maybe the drive train but should have no effect on the warranty on the radio, power windows, A/C and everything else not directly related to the motor and the fact it is making more power.

There are laws spelling this out, Smith Magnusson comes to mind but maybe they just make guns and superchargers :jester

The dealer isn't supposed to deny warranty coverage unless something you do actually causes the problem. More info about this can be around at -

Hope this helps,
