So, how do you explain the very similar performances of those two mercs, considering their torque curves are so different...?
Now, I know correlation doesn't always mean causation, but I can assure you it does in this case; more power DOES = higher performance, no matter how that power is derived or whether it is just a "mathematical construct".
To be honest I'm happy to accept Power IS just a "mathematical construct"... One which makes comparing engine performance really easy....!
