Not only driveline loss,but don't forget the loss form the water pump/alternator/power steering and anything else belt driven on the front of an engine.........
Years ago, a guy had a 360 Dodge engine on a dyno,this particular dyno didn't have it's own water pump,so the engine had the water pump on it and in this case the alternator also.......when they began making pulls,at about 5000 rpms, it would throw the water pump/alternator belt off everytime, pulleys were not lined up properly.....
On one pull it was noted that there was a 14 hp increase as soon as it hit 5000 rpms and threw the belt!!!!!!!!!!!!!!!!
