What you're saying is that the area under the power/tq curve is what's important. That's true...that is what counts. Buf if you're up against an identical car, identical gears, identical gas, identical weight -- such as another supercharged E9x M3 -- and if he has more area under the curve, there's no possible way you will beat him.
I've already asked you to send me your dyno files, but I didn't get any response. Until you do, I can't compare your actual dyno results against any others -- and "overlay" the two. But I can take another AA car in the US with nearly identical dyno numbers as yours, and show you what it looks like.
As you can see, the ESS VT2-625 kit has substantially more area under the torque curve and under the power curve. This translates into real world results. I know you like to think your car can beat any ESS car, but if you raced side-by-side with the ESS car above, you would get completely destroyed (just as other AA car's in the USA have been destroyed as well). For example...
The AA car's best 1/4 mile run is about 122mph, and this ESS car's best 1/4 mile run (in worse weather conditions) was just under 130mph, and he had a verified vBox 1/4 mile run of 132mph. The AA car's best 60-130 is hart to tell because the owner says he's in the low 7's, but refuses to post the results. Most likely his idea of low 7's is probably something like 7.48 seconds. The same ESS car reaches 60-130mph in 6.8 seconds -- nearly a full second faster.
Video results can't really be verified and don't mean much of anything because so much depends on the driver and if he gets a head start on the other car. But vBox files don't lie, and if both cars have vBox's, then I have software the can re-align the two cars to the same speed, then make a video to show who would have won the race. So if you have any vBox files of you car's performance, then I can do this for you. Here's another example why these types of side-by-side runs aren't very reliable. This weekend I attended a track event with two hours of side-by-side racing (just like Gustav's events). I watched many races where the same cars raced each other many times. Sometimes Car-A would win, sometimes Car-B would win. The power on the car's didn't change between runs, but pretty clearly one driver hit the gas before the other. So these side-by-side runs aren't scientific and can't really be trusted to mean anything...even though they are very fun to watch.
