Whine noise after supercharger install

  • Sponsors (?)


Trent,
I have a 2010 Roush Mustang with the same 4.6 engine you run. I have the same Roush supercharger too. I get a whine when the supercharger is building boost. Thats completely normal. Superchargers whine. In your case, you disconnected the drive belt and still have the noise. I know enough to be dangerous about how exactly superchargers work other than they inject air into the combustion process under pressure. Mine is 12 lb max. I could be wrong but trying to get air through your supercharger with it being unhooked may be creating noises too. Did you install all the other upgrades to support the supercharger? I know with some SCs the card needs flashed too.
Good luck!
