Why cant ap1 guys just admit there car is slighty slower then ap2s?
Anyway, the difference between the acceleration performance of the AP1 and AP2 is going to be more to do with start/end speeds than anything. From some speeds, AP1 *does* have the advantage. Stock, the cars are all but identical in acceleration performance from a dead stop. 0-60 ~5.4, 1/4-mile ~14.0 @ ~100mph (yes, there are faster and slower examples of either).
Any difference between the two is in the noise. i.e., test to test and car to car variation is about as big or bigger than any underlying real difference between AP1 and AP2. A tenth or two, mph or two at most.
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.

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

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

please explain me why?. Again I admit that ap2 have a verter start but ap1 reach top end more faster

Not to defend woodburn's obvious biased opinion, he does have a point that the video you posted isn't very good proof.
1. No video from the other car's perspective and what's going on in there.
2. driver skill plays a huge role...and it looked like a beginner group you were driving in... and beginner groups have the biggest variance in driver ability than any other run group.

there is a lot of arguing on this thread lol i've never driven an ap2 but i would probably buy one on looks alone.... i love how responsive my ap1 feels. with all the mods ive done sometimes it feels like the throttle is a little TOO sensitive lol. My solution to the f20c lovers would be buy an ap2 sell the drivetrain keep the ap2 trans if staying all motor, swap out for an ap1 trans if boosting and call it a day 
best of both worlds IMO

I think the point woodburn and others are trying to make is that if one car continues to pull on another car from a roll through each gear, the cars are not even. Period. It's not the case where one car is pulling on the other, only for a short period of time, but one is consistently pulling on the other, through each gear. There's no replacement for displacement.
Quick search yielded two Car and Driver tests within a year of each other, of an '03 and an '04 S2000:

http://www.caranddriver.com/comparis...mparison-tests
0-60
2003: 5.4
2004: 5.5
1/4-mile ET
2003: 14.1
2004: 14.0
1/4-mile trap speed:
2003: 99mph
2004: 100mph
Does the AP2 make more power? Yes.
Is it significantly quicker? No.
You will find more variability in different tests of the same exact car.

Each of these cars will have an advantage at some point on a race track. At a mile it may go to the AP2 but in a marathon more than a mile it may go to the AP1. Don't blast me for stating these very arbritrary assumptions. If it were at a mile and the AP1 was gaining at each point of the race track, it would also be true that the AP1 was faster than the AP2. In this case the only deciding factor is the finish line.

Why you buy 2.2L, You must me in the wrong place then. 
AP1 produced 240hp, and if AP2 can produced 264. Then I might think about getting one AP2.

The ap2 does have more then 240 hp at the fly, dont you see the dyno graphs? The ap2 is putting down more whp over the ap1 through the entire power band. This translates to more hp to the fly originally.
HOW MANY TIMES DO WE HAVE TO GO THROUGH THE 0-60 TIMES, THE OLNY REASON THE AP1 AND AP2 HAVE THE SAME 0-60 TIMES IS BECUASE THE AP2 HAS TO SHIFT INTO 3RD GEAR RIGHT BEFORE 60 MPH. Then after that the ap2 will pull through harder.
