Disabling Supercharger

With winter approaching I was thinking how useless having 12lbs of boost is going to be. I was wondering if there was a safe way to disable the boost from kicking in. Maybe adjusting the bypass valve all the way out so it doesnt kick in until further into the throttle? Not a question people usually ask but it would be nice to have the gas mileage of a N/A Grand Prix-at least for the winter when i dont need the extra hp anyhow.

What year is your car?

couldn't you just not hit the gas as hard? Dunno about that as I don't have a supercharger.

Take off the belt. If your gonna mess w/ the bypass valve you would still be putting wear and tear on the blower by spinning it. Take the belt off, its the best option.

Ripn12s is right. Removing the belt is the simplest way to disable it but I bet the first time you go to pass another car you will decide to put it back on in a hurry.

So the intake path wont be affected by taking the supercharger belt off. thats what i was wondering

If you are running 12 psi of boost, I'm assuming it's not a stock SC pulley, so why not consider putting a 3.8 back on for the winter. Problem solved and you will still have the potential of your supercharger and no loss of fuel economy. And if you do not have a modular pulley system think about getting one for future consideration. Good luck!
