Spec sheets just look at maximum hp/tq. It does not take into consideration how the power is made, what the power curve looks like, how long the engine stays at the maximum tq.
A stock m42 E36 with DISA has a definite hole in the powerband right around 4500 to 5100RPM.
My car makes great torque down under 4800, but makes crappy tq after 4800rpm. Horsepower goes up dramatically after 5000RPM. |
