What box is that on? Is 30% loss through drivetrain typical? If is a Subaru, wonder what transmission loss is on a VW box. Torque is pretty up the Rev range, assume that’s the 16v heads?!
it builds from 3000 and is lovely and flat then picks up again. 30% loss is fairly normal, certainly nothing to worry about. box is 4.44:1 diff so quicker acceleration but higher revs at the top end for the mph.
