Dodgy dyno sheets

This doesn't look right to me. For starters, I always thought that the torque curve and power curve were supposed to cross @ 5250rpm..........



Any thoughts?

That's what I thought, and assuming these people know what they're on about, this suggests the graph is wonky.

Only if the power and torque axis are to the same scale (and using units of bhp and lb ft).

Only had a quick look, but if you read up from approx 5252rpm along the bottom scale and check where it meets the power and torque curves, it seems about right- 150 bhp/150 lbft.
