you serious? What is "inferior" to you anyway? is it inferior for someobody who lives in a city with consistant stop and go traffic? Is the At an inferior product for a paraplegic? And no its not fair that everybody dismisses At without trying it. Im not entirely sure what your trying to say by evangelize the AT.... im not even sure you have used that word correctly. This post is just asking a question. Not trying to get approval, or pats on the back... just a simple question. Dont be a dick bro.
Not inferior for my purposes...

not to beat a dead horse....from a roll ive seen 2 MT rx8's in my rearview mirror. I was of course cobb tuned, cia, and catless...That video of the 9300 rpm AT was mine.. I dont have the videos of the "rolls" anymore they were on my old phone. they were done on a closed road in 2009. As far as I remember the manual rx8's were BONE stock. Oh and from a dead stop I beat one of them, the other one barely beat me we almost door 2 door. But from a roll i beat both.

never had transmission problems..shifted at 9k daily. when i was at the drag strip I would shift at 9300 from 1st to 2nd gear..then about 9100 through the rest of the gears.... remember the rear gearing is different than the MT, so there was still something left up there in the powerband....i think....at least it felt that way.. Experts correct me.

BECAUSE RACECAR
My gf has an AT 4 port and I have the MT, I drive them both all the time and its a completely different car. I know the 4 port can't be compared to the MT but to me they are not the same. and as far as price her's was a little cheaper then mine but I had 40k on the engine and she had 70k. I think she shouldn've just boght a nicer MT and just learned. She was doing fine learning in my old RSX but when I tried letting her drive the 8 I think she was scared and didn't want to break anything lol

Right. I bought my car for transportation (commuting and long distance weekend trips), not racing. So, I got the higher geared A/T expressly for that purpose. The higher gearing enables tank averages between a low of 22 mpg and a high of 28 mpg, and normally around 25 mpg if I'm just driving normally. On top of that, the lower cruising revs make the engine virtually silent and the drive more relaxing.

Congrats to you on that.
Secondly the engine was replaced within a week prior to my purchase.
Furthermore i enjoyed the paddles and found them to be quite responsive.
However i made some assumptions that id like some opinion on. I figured that the at 6 speed auto tranny and 6 port motor cant be to far off from the performance of the praised mt model. With a accessPORT the rev limit on the auto can be set to 8500, thus giving the extra hp the mt has over the at. More importantly the change to the next gear would land higher in the powerband. Apart from launching and a drivers ability to shift quick there isn't much that separates the at and mt.. correct if I'm wrong. So from a role the two different options would be relatively equal. I have searched and found very little info about 6spd at's.
First off, the driveshafts in the autos are steel, while the driveshafts in the manuals are carbon fiber. That helps with engine response a bit in the higher rev range, and also decreases the rotational mass that the engine has to spin.
Second, you completely forgot about the rear end gearing differences between the autos and manuals. 4.44:1 for the manuals, and 4.30:1 for the autos, IIRC. The Series II manuals increased the rear axle ratio to 4.78:1.
Third, you didn't mention if your car has the LSD rear differential option.
All manuals come with LSD, where as not all autos come with it.
Next up, I do believe the fuel injectors are different between the auto and manual 6 ports, but I could be wrong on that. If there is a difference, that's a major thing to consider. There most likely will be different fuel cut off points, which can be modified with the accessport like you mentioned, but you would still have to replace the injectors to equal the output if there is a difference.
There's nothing wrong with the car you bought.
There's nothing wrong with the reasons why you bought your car.
And there's nothing wrong with wanting to improve your car a bit, too.
If you wanted to have fun with it, you could slap in the couple of parts that would make your car equal to the manual transmission cars (rear diff, driveshaft, fuel injectors, accessport tuning), and see how much of an improvement you get in your car. I bet it would be significant.
Best of all, it is all 100% reversible.
If you want to even approach it piece by piece, and do some timing runs after each modification, feel free, that way you will then have data that no one can truly refute.
But its up to you to decide what you want to do with your car.
Just do it for your own reasons, and don't look to others here or elsewhere for justification of those reasons,
BC.

my other car is a 787b
Cool video - I've always had a hard time finding good AT videos.
Anyone have links to 6port AT laps on a track?
I'd like to see how fast the downshifts happen and how well it blips the throttle.

I hate when people bring up the fact that a good driver in an AT can drive faster than a bad driver in an MT when comparing AT and MT. If you're going to mention that, you might as well mention that the AT with tires is faster than the MT without tires. With a good enough driver in an RX-8 and a bad enough driver in a supercar, the RX-8 is faster. That doesn't mean that the RX-8 is actually the faster car. If you're comparing 2 cars, you should assume for relatively equal circumstances with equally skilled drivers.
Based on the OP's post, I'd imagine he's mostly talking about acceleration in a straight line. The difference is probably less noticeable at a road course, especially if there aren't any long straights. Any decent driver should be able to, at the very least, keep up with an AT and will likely pull a bit. Someone who is good at driving MT should easily pull on the AT.

@8MANIAC..... you're right. It's easier to drive an AT than a MT... plus I dont know the condition of their cars..A human cannot out shift a computer no matter how good you are. Here's something I did to take advantage of that..
In automatic mode, it will shift automatically at 7500, even though I was tuned to 9300. You had to go to shift-tronic mode to get that high. What I would do is start off in shiftronic mode..when I got to about 9200 I put it back in automatic..when you have a "slushbox" theres a delay in shifting. But when I did that there was hardly any delay. You'd have to have an auto to understand I guess.

There seems to be some confusion over the difference between a true automatic, and automatic with paddle shifters, automated manuals and dual clutch transmissions. They are all different.
The RX-8 comes with a true automatic with paddle shifters.. essentially the worst of the bunch. Its still a standard slushbox with the only added addition in that you can "sometimes" tell it when to change up or down. You still have the power sapping, belongs in a mini-van torque converter. Popular names for this include "Tiptronic" and "Manumatic". Guys who drive their sports car like it should be driven know this are almost painful to use... There is almost nothing sporty about it.
An automated manual (or semi-automatic) transmission is really a true manual, however it will uses cables, pneumatics and pumps to actual shift the gears and engage/disengage the clutch. Popular uses are in Ferrari's "F1" transmission that's been available since the F355. BMW's SMG and Lamborgini's e-Gear also uses this technology as well as many others...
A modern variation of the automated manual is the dual-clutch gearbox. This will utilize two clutch-packs, one for even and one for odd gears. VW made this popular with its DSG gearbox.

You do realize that you don't have a PDK, or an SMG, or a DSG in your RX8, right? As you said, you have a slushbox. You don't have the type of transmission even capable of a sub 300ms shift, and seeing as how a manual transmission can be shifted in less than 500ms, that kind of blows away your little theory about having an advantage, doesn't it?

I'm definitely not trying to turn this into an 8 bashing thread, but I think it's funny when people think or expect that the rx8 is just amazingly fast in terms of acceleration. Even when I owned the 8 and people would ask if it was fast, I'd be modest and say it's not meant for straight line performance but is still decently fast. A lot of friends thought it was pretty fast when I'd go WOT in the 8, and it definitely is above your average car.
With my S4, on the other hand, I've had people ask me not to go full throttle after a couple quick pulls. Coming from the 8, it was definitely a completely different beast. I even got a little intimidated when I was first easing into higher boost. Now that I'm used to it, I'd have a tough time with a car that lacks power. I can definitely see why people get "addicted" to power/straight line acceleration. Having owned cars like the 8 and my S4, I need a car that has both power and handling. I'll be the first to admit, my S4 doesn't have the most confidence inspiring feel when it comes to handling and that's one of the areas I intend to upgrade as soon as possible.

lol... ok yaxman.. ill let you be correct... but i don't own a slush box anymore...I sold that car. It will be a while if I ever delve into another rotary powered car... If I'm correct you live in texas right?? maybe we should meet up so I can show you what I drive now.
EDIT: ok so you live in Austin...not far from me.. whats a good time so I can show you my so called slushbox?
