you are all nuts... despite how magnificantly engineered the f20 is, it is still 2 liters with no forced induction and 4 cylinders, that combo is just not fast in a straight line. Fast for a 2.0 four pot? hell yes, but it depends on your definition of fast and that is why there is no right answer to anyone opinion

No, I posted a chart that shows they have *similar* power under the curve.
2-3 shift at 8200 rpm would put the AP2 at 5940rpm, but to not punish the AP2 too much, lets say it puts it at 6000.
The same shift in an AP1 from 9000 would put it at 9000(6000/8200) = 6585rpm.
Here is what the "power under the curve" looks like for an AP2 from 6000-8200rpm vs. AP1 from 6585-9000rpm:
So lets sum the areas.
AP2 area under curve = big blue rectangle + small blue rectangle + blue triangle
(8200 - 6000)*155 + (8200 - 7600)*(202 - 155) + 1/2(7600 - 6000)(202 - 155)
= 341,000 + 28,200 + 37,600
= 406,800
AP1 area under curve = red rectangle + red triangle
(9000 - 6585)*162 + 1/2(9000 - 6585)*(195 - 162)
= 391,230 + 39,848
= 431,078
Whaddya know, the AP1 actually has more area under the curve...

. I rev to 8500

I think that they are a few changes in trannys ratios on ap2 to favor the torque but hurting the top end

From a roll race ap2 always wins...no driver involved when roll racing.

Why cant ap1 guys just admit there car is slighty slower then ap2s? Yes ap1 is more of a drivers car and I really enjoyed driving my old f20c a lot more of a thrill, but if you lined then up on a roll race the ap2 will always pull ahead just slighty I have seen it way to many times.
There was a magazine that did an article about the new ap2 when it first came out. They did acceleration test and proved the ap2 was just a tad faster and then they did back to back dynos and they EVEN QUOTED THAT HONDA IS NOT TELLING US EVERYTHING ABOUT THE F22C AND IS HIDING HORSES POWER SOMEWHERE.
