Enough?
And.. if you stuck a thermocouple in the insulation at 8 inches, you would see that the tempature of the insulation would in increase dramaticly as you added more and more. So, when you are idling at 2000 and turn the furnace up to charge, you would have to heat up all of that hot insulation..
