can someone give a quick description of what exactly this means?

 

well its about dyno graphs of course. when you have a dyno graph in front of you, you can compare a couple of things. One, is peak numbers; how how the graph went, maximum horsepower and maximum torque. These numbers aren't good for much other than bragging rights.

Area under the curve: this describes kind if the shape of the curve. like if two ITRs both have a peak of 195whp, but one has a lot more 'area under the curve' (ie low end, mid range, not just top end) then that one will be faster.


make sense?

On a dyno chart there are two lines (aka curves), one for hp and one for torque.

Say we both make 200whp/140lb-ft at PEAK. I could have an almost flat line curve, which would give me way more area under the curve than you.

Area under the curve is when you're talking about power everywhere on the chart, not just at peak.

 

It is the total area under the horsepower or torque curve when you look at a dyno graph. Experience tuner will look more at getting the maximum surface under the curves (meaning maximum HP or torque throughout the RPM range) instead of concentrating on just peak HP or peak torque. This usually gives a faster car.

 

makes sense to me...thanks!!
