Just the facts
412 'classic' has five fuel cells, similar to the 212 and holds roughly 220 Gal.
412 SP/HP/EP has 10 cells, six in the floor, four in the back for about 330 Gal
The 412 'Classic' and 412SP use the torquemeters off the Cbox to read torque, eng1 + eng2= MGB Tq
The 412HP/EP use torquemeter for eng Tq but phase shift mast for mast Tq, so eng1 + eng2 is not necessary equal to mast Tq.
Typically, worn/eroded blades don't have a big effect on performance for the 412; what you see in the charts is what you get.
