Sounds like a lot of people here need to learn about gearing.
All you care about when you're accelerating is accelerating. "Peak output" of the engine doesn't mean a damned thing, it's power at the wheels that matters.
Your total linear force, the total force that you're putting to the ground, which is what matters when you're accelerating, is a function of both your engine's output AND the multiplicative effect of the gear that you're in. Try accelerating at "peak power" in 5th gear and it'll be pretty clear how much slower it is than accelerating at 9000RPM in 4th, no matter the fact that your engine is making "less power".
Just because you lose 5% of your peak power by going a little further along the rev-band doesn't mean diddily squat if you lose 50% of your gearing advantage. Just imagine shifting from First into Fourth. It doesn't matter if you shift at "peak power" or not, you're gonna go nowhere fast. The same effect happens on the 1-2 shift too, it's just a lot less noticeable because the gear ratios are closer, but that loss of gearing advantage is multiples higher than the relative meager loss of power between 8500 and 9200.
The actual feet per second that you're accelerating will be MUCH greater by holding your gear than you'll get by shifting "at peak" and this effect is magnified because when you do shift later, you'll end up that much higher up the rev-band for that next gear as well, bogging that much less.
Go to a track and watch what the V8 owners are doing. It doesn't matter that they make peak output at 4500RPM and it's all downhill from there (and to a much greater magnitude than the RX8 experiences). They're gonna shift at 6800 anyway. Because even though their engine is 'petering out' so to speak, the power at the wheels, the power that is actually moving them forward, is still greater than it would be if they went to a higher gear.

Thank you for clarifying everything! That's what I was trying to say, but you said it much much better.

Oh well
The beep is there for a reason. To let you know where you are at the powerband. By the way with the RB flash your powerband is extended to 9800 rpm. I'm glad it beeps, sometimes i dont know how hard I have pushed the 8.

wow i didn't realize the rx8 makes peak power at 5500! that's news to me. could have sworn it was 8500...
although i am naive to expect a sensible comment from someone who boasts utilizing synthetic oil of the wrong weight no less...
But anyway, the point is really quite clear: the loss of power from 8500-9000 range would not be nearly enough to offset the 36 percent loss in leverage when shifting to third. (the loss is even more when shifting from first to second).

well, power equals work/time. torque is the work part of that simple equation. so stating that peak power IS the torque...is mathematically so nonsensical it was difficult to not make fun. but ya sorry i guess i could be more polite.

"Fix" found kinda
so i found this thread because my beep went away and i could not find out why. i personally like the beep, but for those of you wanting to get rid of it...i recently bought an auxillary adapter that plugs into the back of the head unit where the mini disc player would normally fit. when the headunit is on CD, radio, or off the beep still remains but when the adapter is activated and the system reads EX^3 the beep is disabled. for those who want no beep and planned on fitting your 8 with some sort of auxillary port there you go, for the rest of you your SOL.

Best fisx is to mod it. Then you can't hear it.
Loud in take KN and or exhaust.
Take it to the take.... can't hear a thing with a Helmet.
Listen to the engine..............
