6at vs 6mt
 

First off id like to note what lead to my descision to buy the auto i currently own. It was significantly cheaper than all the mt's in my area.. most likley because it is the less desired modle. 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 powerban. Apart from lanching and a drivers ability to shift quick there isnt much that seperates the at and mt.. correct if im wrong. So from a role the two differnt options would be relativly equal. I have searched and found very little info about 6spd at's.

I'm not sure what you are asking? Are you asking anything?

Congrats on your purchase i suppose.

There's a whole section dedicated to AT specific mods. You should probably start there before you're banned for starting yet another AT VS MT war thread.

sorry, what im asking is are my assumptions correct. Would a 6 speed auto ( redline at 8500) stand up against an MT from a role. I dont see why it wouldnt.

The reason the AT is limited to 6500 over the MT 9000 is because the automatic transmission can't handle RPMs that high.

AT limit is 7500...

the AT won't stand up to the MT, it actually won't even stand up to a stock miata in a straight line fight on the track.

But...it is still a damn fine car, you just can't launch it. I had TONS of fun in mine.

There is a big difference in MT and AT. You should ask Dr. Google.

You guys are underestimating the 6 Port AT with the 6 speed paddle shift tranny and it's obvious you guys have not driven one. REDRX3RX8 tracks his 07' Auto and hangs with stock 6 speed manuals just fine. Jcabbie, andother SARX member has a 2010 Auto with the Revi intake and catback and it hangs just fine with stock 6 speeds.

Now if you are talking a 4 port auto versus a 6 port 6 manual then yes it would be a slaughter.

6 port AT is pretty brisk, but 6 port MT gets your the best buzz.

Yeah there is no doubt a 6 port MT is quicker than an AT but the difference is not huge (with 6 Port AT's) and in my experience, most people who do drive 6 speeds MT's, don't do so very well. That is why you see RX-8 1/4 mile times vary as much as a full second between stock cars.

I tracked and auto crossed mine numerous time. It is a great car but you will get killed on the straights.

The problem I always had was not being able to down shift at a time where it was needed where I know damn well it should have been able to do but the car just won't let you. And once you hit 4th gear, it is done.

4at was probably a half ass job on a rotary engine. not very suited for the power band.

All RX-8's get killed on the straights unless they are FI.

To be clear. I am talking about the 6 port 6 speed auto. Yes the 4 port 4 speed was a fail at best, but im not refering to that.

I read alot of posts here before i signed up, it accually seems to me that alot of rx8 owners are unaware that there is 2 differnt Automatic Transmissions. They are 2 very differnt machines.

It's fine you made a decision to buy an inferior product because of price. That's your choice. Own it, and stop wanting everybody pat you on the back for it. You also don't have to evangelize the AT RX8 from now until eternity. Enjoy your car.

LMAO ya more than welcome to bring ya mt and race my wife. "A mere woman" with an auto. Always a pleasure to see ppl that can't drive lose.

you seriouse? 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.

Your own words, brah. Your own words.

Less desired doesnt always mean inferior.. brah. Nor is that the topic of this thread.

And here we go...

Go? It's gone. ;)

Is it time for me to mention Jim Hall and the Chaparrals again? Two speed Powerglide? Beat the crap out of everyone else in USRRC and Can Am?

On a les frivolous note...and in the spirit of the original question... If the ECU on an MT 8 is modified to raise the rpm limit, what are the consequences? Does the torque converter stall? Explode at 7501 rpm? Or just not last as long?

Well just from reading around, alot of AT owners seem to do this

OP: at the end it's all a matter of personal preference. One tranny is not better than the other just different.

Personally, I prefer manual. I think the RX-8 can be more fun with a manual tranny - especially around twisty roads when you downshift/up shift very quickly while spinning the steering wheel like crazy from side to side, lol

But if you found the right deal with an auto, then make the best out it and have fun with the car!!!
