I wouldn't count on that with either the super or turbo chargers. You are going to be increasing your engines power output... it does that by burning more fuel. Burning more fuel is going to be putting out more heat. You may very well need to go back to the stock pulley to restore the cooling capacity (less flow) you lost with the underdrive pulley.
