My mistake. I had thought the AP2 was bored. I still think, however, that the 8,000 redline is simply to protect Honda from the warrenty claims that arose from overreving the engine on the downshifts.
I agree that the pistons are traveling faster and farther, but I think the engine could have stood 9,000 rpm. I think the 8,000 rpm redline is a result of American Honda and all of the bent valve warrenty claims.

All manufacturers set RPM at a point that will minimize damage and warranty claims. But there is a good reason for that. The fact that 90% of the engines can tolerate another 4 or 500 rpm 90% of the time means that at least 10% of the folks will run into some sort of a failure at a higher RPM.

Guess I'd better run out and buy that extended warranty I haven't decided about yet. Can't have my pistons, rod and crank in jeopardy. +1 feels the changes that Honda has made to the new engine are excellent changes, but he has similar sentiments to those that Matrix addressed earlier about rpms, etc. I am very conscious of over-revving ANY engine and watch those rpms. The AP2 sounds are more subdued than the AP1, so I've become more in tune with watching the tach than I was with the old one. Bear in mind I'd driven the 01 for almost five years, so I often felt I'd become "one with the car". Its going to take a little time to grab that feeling with the 06. I have NO REGRETS about making the switch and think it was the appropriate decision to make. I do feel kind of sad for all those folks who never had one of the AP1s and whose only experience with the S is the AP2. The AP1 gave a sensation of raw sports car driving that I really do not feel with the AP2. I'm not underestimating the AP2. It is FINE, but it is not as appealing to the purist heart as the AP1.

You can bounce of the rev limiter and it will not hurt the engine - just sound terrible and if your on the track or autoxing you'll lose time...

Not to worry Val. You have no real worries unless you misshift or alter the rev limiter to a higher cut out point.

Don't worry about over revving unless you accidently downshift into the wrong gear.

+1 tells me all the time not to over-worry about over-revving since the rev limiter prevents engine damage. I'd never alter the rev limiter and I'm very concious of hitting that limit. The only time I've ever done it I felt that I should go sit in the corner for doing a really bad thing. 
I noticed at the nor'easter when folks were getting their cars dyno'd that they hit the rev limiter several times every time. That's why its there, so any safety measures that save my engine life are okay by me.
