What takes more fuel? HP or Torque

[sqr]

What requires more fuel and or air flow on the power curve. Max HP or max torque?

By Leaning the fuel on a car,you will get more HP.So if you add more fuel ,you will get more torque......

Lets say peak tourqe is at 3500 rpm and peak power at 5000 rpm. Is the motor comsuming more fuel and air at 3500 or 5000 rpm? Would i want a different afr at these two points?

The Motor will be gettin more fuel at 3500 rpms.

You will have the highest airflow at peak horsepower. Torque has nothing to do with airflow. It is directly related to cylinder pressure.

ah sorry, the engine will consume more air and fuel at max HP, assuming the AF ratio isn't messed up.
Torque is, by definition, getting the most airflow for each crank revolution.
So injector pulsewidth will peak at peak torque, and injector duty cycle will peak at peak HP, again assuming the AF ratio isn't messed up.

Personally I like to see the AF ratio a little richer around peak torque.

... horsepower is torque over time. Basically, if your fuel mixtures are stoich, you're doing it right.

How did you arrive at this conclusion? The 'more torque when rich' conclusion.

you cant be serious..... can you?

the motor will have much higher IDC's at 5000 vs 3500, there for flowing alot more fuel.
