OK, I am not so naieve as to think you can give me real numbers, but....
I have an "01" with FlowMaster cat back exhaust, open air cleaner, 4 lb
(8.5" measured accross flange) lower pulley.
My top pulley measures about 3 1/4" on outside of flange. I read stock is 2.93 so I assume this is a stock upper if one subtracts the flange.
Anyone with an educated guess??? i.e. aaded HP with cat back?, added HP with open a/c element? added HP with 8 lb lower? all estimates??

One more question: from the drivers side exhaust manifold there is a 3/4" tube going to the EGR valve ?? some large unit near top of motor. Off the 3/4" tube are two smaller tubes. The smaller tube most forward goes to a small rectanguler boxed piece up near the blower. The rear small tube closet to the firewall is the issue. Where does it go? where is the pice located that it goes to etc?
thanks

I am new to these trucks and superchargers. Everything on the truck came with it and no explanation from owner.
Looking to meet other owners in New England area before I have to put it to bed for the winter.
