Kevtex... I have read your posts and for the most part agree with all of them except this one. The power requirement is not the same to get it from a belt as it is from the exhaust. When you take it from the belt you will suffer a larger power requirement due to the parasitic loss etc and you are taking power to make power. Gaining it off of exhaust gasses doesn't cost anything. The engine is shooting out the exhaust gasses whether the turbos are there or not so you are not taking any power from your engine to make the extra power (boost).
