Power vs Torque

[Andy1GP]

I have always believed that the best comparison for torque and power is the area under the graph. This gives a good idea of power and torque available through the rev range rather than at peak revs.

That's why I love people that cherish their peak dyno figures. Enter with your less powerful car and beat them on the road then they all think you're hussling them

Exactly, the only race it will win is the Dyno race.:biglol:

completely agree people get carried away with peak numbers alone when the curve is what you really want to look at an engine that produces high torque over a few RPM is not as good as one that produces slightly lower torque over a much wider RPM unless you only going to use the engine is the narrow torque peak...

best torque curve is a flat one till redline... this is very difficult to get right though

Vanos almost achieves this. IIRC while the max power output of the s50 e36 M3 and s54 e46 M3 was not that different the power and torque delivery was vastly improved.

vanos makes a huge difference
have a look at the e90 M3 some very special magic was done there :rollsmile:

Yes! Vanos felt awesome even on my snail-like 320i. Also sounded great.
