Auto 05 Rx8.....Just not pulling that hard...?
 

So Ive had my 05 rx8 auto (with tip) for a few weeks, and it just Doesnt Seem to Pull all that hard..... Im wondering if maybe there is something wrong.....

My grandmothers v6 camry will smoke my rx8 from 0-60 any day and I see that as being somewhat fishy........:confused: I cant even break the wheels free when accelerating hard (no tract cont)

It recently had a new motor put in it and I was wondering if maybe there might be a problem with it. If I were to take it to the mazda place, would it cost me anything to have them test it, and if I do will they try to charge me through the roof?


Or is it all just me:dunno:

You have a 4-port/4-speed automatic. You put down around 130hp to the wheels

Rx8s lack tq, u shouldn't be surprised.

Yep, 4 port auto = slow. Hell my dads Titan gave my car a run for it's money when both were new years ago. I think the V-6 Camry has about 100 more HP.

try smoke the camry in a corner:boink:

Sounds like someone should have done some research before purchasing the car.

As mentioned before, the 4 port autos made a lot less power. With a good set of tires, it takes a little effort to break traction in a manual, so it should be expected that the lower power auto with no means to "launch" would have less ability to break traction. With my 245's on, I haven't been able to brake traction from straight out accelerating... mostly results from aggressive shifting etc, which is not that often as I don't intend to destroy the car.

Even if you didn't do research, you at least drove that car or another automatic 8 before you bought the car, right? If not, you don't really have much to complain about.

How does it feel knowing that your grandmas car is faster than yours?

He just got

Ok so at least there isnt anything wrong with the car then from the sounds of it. I would have just thought that an auto rx8 would still be able to at absolute least keep up with an auto camry.

Oh well, I guess in that case Im not as suprised. Just asking because when I test drove my friends auto 06 before I decided to get mine his pulled a little harder than mine does now.


But now the real dilema- I have the option of strait up trading in for an 04 manual with 81k (mine has 70k but brand new engine)

So by doing it I drop a year and gain 10k and not a new engine but gain a manual, So what do you guys think? Should I

The 2006+ automatic has the 6-port drivetrain and around 25-35 more horsepower.

Turbo, Supercharger or Nitrous. That will speed it up.

well we dont know. youre buying the car.

Looks like you like going faster than your RX8 in a straight. Just steal your grandmas Camry for now.

Yikes. If I were you, I'd be disappointed with my purchase. Ultimately, that's your choice on the trade. You're assuming a completely different car in who-knows what shape. You could be destined for issues, but it comes down to what you feel it's worth to have a manual. As far as overall driver satisfaction, I'd say do it. I've never driven an auto RX8, but the thought of it makes me vomit in my mouth.

lol Rough Crowd. Yea man trade it or mod it if you want faster.

It's risky to just jump into a whole new vehicle, but the manual is just so much better. I really regret getting an A4, sad thing is I know how to drive manual, I just didn't think it would be THIS big of a difference. Now I am sad and want to trade in for an M6!

if you want fast, jus try an sell it and buy an FD lol's

meh, Lotus Elise Supercharged for me.:lol:

Screw that. I love my auto RX8, though it is an '09 with a 6 speed auto. While I might not have the redline of a manual, it's so nice day-to-day and it'll shift as fast as a stock manual.

Yea minus the HP of a manual.

Horsepower is a function of torque. Our cars make the same about of torque always and horsepower until I hit my redline. If I removed my rev limiter, then we'd have the same amount of horsepower.

This is why I just mentioned the redline, and not the HP, as it isn't relevant unless redline is mentioned.

^^^ your car still doesnt perform like MT's, You have a Steel driveshaft as well as your car weighs a good 100lbs more because ATs are heavy... Lets not forget when that AT tranny fluid warms up and starts getting hot the Flex Plate starts slipping and the shifts are no way as fast as a MT...

Ask me how I know these things... I used to have a AT RX8... Dont compare a slushbox with the ability to control gears to a manual transmisson. The AT is no SMG or dual-clutch transmisson...

Hate to break it to you... not trying to bash you but point you in the same direction

I completely understand they aren't comparable when performance comes into question. I obviously traded some performance for some comfort.

I was just saying that the auto wasn't terribly behind. Then again, I was coming from a auto '91 T/A daily driver, so any new auto will seem like the most amazing thing ever. But otherwise, I've driven my share of manual's, and one DSG GTi, so I can appreciate the performance when needed. My saying the auto isn't all bad, is equivalent to someone with a M/T saying the clutch is easy to use day-to-day. It's not as easy as a auto, but it's worth mentioning instead of disregarding completely.

At any rate, in respect to the OP, neither the auto or manual will pull particularly hard, as the car isn't very torquey. And besides, handling is amazing in all RX-8's!

Wait what!?!? 130???? It definitly says 189 on all the stats ive seen....????

189 to flywheel. 130 to the wheels after drive train loss.

Bren, sorry but yes, that is around what you put to the wheels.


WBRotary! - The 6speed auto flappy paddles are an absolute blast to drive around, and track with. I don't feel that it is as sloppy as you describe it. When I am just putting around, it has a casual gear change, but when I beat the living hell out of the car (track only) they change with very little hesitation. Sure it's not an SMG or a dual clutch, but it is still fun as hell

Yeah WTB,

REDRX3RX8 also tracks his car using the paddle shifters due to his disability and trust me, you would not want to track against him.

Flexplate not flywheel, automatics don't have a flywheel

Maybe the 4 speed was slow, as that's what I had. Yes we all know automatics are faster on a track because they
can shift faster but that does not include the AT transmission in the 8. The AT in the 8 is still a slushbox and the MT will perform better assuming you know how to drive. Yes you don't have to heel-toe downshift into a corner and that makes it easier because you just
have to hit the - paddle. Regardless MT>AT



Paddles are easier than shifting, we all know this, but considering Mazda didn't develop a special AT transmission for this car the MT will perform better on a track, once again, assuming you know how to drive one.

Your funny dude.

Dont make fun Scott, its true... You of all people should know it... :)
The AT transmisson is nothing special, its not a SMG etc. When temps starting getting high delayed shifts start to happen, atleast on the 4 speed, and dont say they dont because you havent had a AT 8...

Driving both I can tell you (should be fairly obvious), that hitting a paddle is virtually the easiest thing out there right now, theres no doubt about it, but the fact that the AT transmisson wasnt designed to be the main transmisson in the 8 means it has the usual slushbox flaws... I can only say this for the 4-speed/ 4 port AT rx8 but I dont see why the 6 speed AT would be any different... Just different ratios and 2 more gears...

Hmmm, so what about swapping out my 05 at with like an 06 or 08, would that make any difference?


I know there is a lot of extra weight, Is there any ways to reduce it?: Ive heard that the carbon mt driveshaft is the same as the auto just carbon,,, is that true and if so should i get one off line and switchem.

The problem is that thing between the engine and the driveshaft.

...trans...transmitter?..transformer?..transducer? ..hmmm...

Automatics are giant hydraulic pumps so energy is converted differently than a gear box. Low torque is not good for automatics. My Corvette is 4 speed auto and it chirps the tires shifting into 2nd gear with like double+ the torque and pulls quarters under 14 (bone stock).

if the 05, 06, 0r 08 is a manual, you'll feel a huge difference....

yes auto fail i know this a manual 8 is decently fast but autos are pitiful lol

I actually have owned an 09 AT and got rid of it. Now own an 04 MT and have to say although older I prefer the MT. It feels a lot more natural to me and it is faster, and I love the short shifter and gearbox.
