Run a temp gauge on it.
BW's will start slipping quietly before they are going to fail.
Usually you will see the oil temp rise when this happens.
Put the temp gauge BEFORE the oil cooler so it doesn't mask what's going on inside.
When you do see the temp creep up, you know it's time to open them up and freshen them up. At that time you can consider adding clutch packs to it. There are several upgrade paths in escalating cost brackets you can explore. Thinner driven plates and friction plates can be used without any machining - THEN you can add machining to removeable parts and get even more plates in it - THEN you can get the cases machined as well, which allows the monster upgrades.
Lube temp is your best indicator of what's going on in there.
Learn what your cruise trans temp is, and take note of what your WOT trans temp is.
Anytime you see those numbers higher than usual, do not ignore.

Oh, a stock 72C in fresh condition is rated at 595 ft-lbs.
That's 200hp at 2000 RPM or 500hp at 4600 RPM or 600hp at 5600 RPM.
Carbon clutch discs will get you 10% to 15% more capacity.
