I've seen lots of mention of a speed up pulley
There is NO such thing. What all this hussle and bussle was about is people are using the center deck pulley from the 44/50A series mower decks on the 44/50 series decks, which creates faster blade speeds. The change in the center pulley was due to the fact the IH went from a Mechanical PTO to a Electric PTO (starting with the Q/L series tractors).

There is NO change in the center pulley for the 44/50C series mower decks (to accommodate the 5/8" Mule Drive Belt).

Now, there is nothing to be said, if you want to custom fabricate something to get faster deck "tip speeds".
