You may have gotten a defective supercharger or the gasket isn't sealing properly. Why did you change the supercharger? Were you having other issues before the change? HTH. -Jim


I was trying to put a smaller pulley on but ended up having to replace the snout

Then yes, I'd suspect a defect or improperly installed gasket. Double check your electrical connections as well. Make sure everything got plugged back in correctly. HTH. -Jim
