RX8 is horridly weak at low RPM. My friend has to launch at 4k+ to get a decent start when we race at stop lights for fun. He has intake / exhaust and super light drifting rims (I forgot the name, they're 3 double spoked, black with red outlines).

Yeah but dropping the clutch at 4k all the time will cut the life of the clutch pretty quick. I should know I have a 1987 Honda CRX that has needed 4 clutch replacements in its lifetime. That and the tires where going every 2 years. I can't do that on the g35. I don't want to have spend about thousand bucks replacing my tires every year or two. The Honda was easy I could get 4 tires installed for about 200 bucks.

 

ya...but the debate is not if the rx8 can last longer...the debate is...of optimal times of an automatic g35 vs a manual rx8..and i am saying...it should be close if its optimal.....

 

OK did some more research and maybe I was a little off with the numbers but not with the logic.
Iv seen reviews (all on 6MT) that say the G35coupe is anywhere from 5.5 to 6.2 for 0-60. This leads me to believe that the 6.2 is without launching and the 5.5 is getting the optimum time from our car. Therefore the 5AT prolly gets 6.2-6.3 without launching and possibly as low as 5.5 or 5.6 with launching at 2-3k.
I have not timed my 0-60 but if i can pull a 9.5 1/8th then i cant be 0.7seconds slower on 0-60. This would mean an AT makes up 1/2second 60-75 which isnt logical.

And the 6.0 for RX-8 is optimum...or at least iv never seen any review post better...

its very very illogical.....i mean..not your statement...but saying that an auto g35c can pull 5.5secs 0-60..i duno man...i just dun see it happening to a stock

 

i honestly dont know what an OPTIMAL time from an AT would be...but i do know that if optimal 6MT runs a 14.2 and the optimal AT runs a 14.4 that in those SAME runs the 6MT would get 5.5 for 0-60 and the AT would HAVE to be less than 5.7. I know the auto loses a little more in drivetrain but I would think the gear ratio (5 vs 6) is the main difference in the 0.2second difference. and therefore the 6MT would actually be increasing to the 0.2 differential through 3rd and 4th gear.
Im strictly workin on logic here but I dont see how the AT could be that much slower off the line and still be close at the finish.

ok...people help me here...or correct me...i am guessing...the manual has a low 0-60 and high 1/4 mile(as you claimed) is because that the manual will definitely have a better launch (even if you auto people do a break/torque launch)...i personally don't know how the 1/4 time for them are as i don't really have the spec with me...but when i checked edmunds....AT 0-60 is 6.2 and MT is 5.9...i think you are overly optimistic about g35's speed...i think the only way to achieve the times that you stated are at certain places either with somewhat of a slope or somewhat weird sea-level..anyhow...my point is...you cannot compare a particular auto time vs the manual time...and then take the difference and apply to the best time of an AUTO... a good analogy would be even if your auto gets a better time than a particular manual by 0.5 secs..you cannot use that time and say that...oh..since the manual can go 6 secs 0-60..my car must be able to go 5.5...you see what im saying?

 

ok..all in all..i am just thinking you are rather optimistic about the speed....i don't think an auto g35c can make 5.5sec...thats..pretty much what im trying to say

 

and i personally don't exactly know what you mean by..."i got 9.5 1/8..without launching"......i don't exactly know what you mean by "without launching" with an automatic...how do you want to launch with an auto? brake/torque launch? revv up in neutral and shift? you can't really do that with an auto..you don't even have a clutch for one....if you want to do brake/torque launch..you won't get pass 2K...so..i don't think you know exactly what launching is...

 

your probably right...all I am saying is that the AT will be 0.1 or 0.2 seconds slower 0-60 given an optimal run than the 6MT. MOST reviews give the 6mt around 6.0flat but I have seen ONE say 5.5 and i dont remember where. On that same day and same track, a 5AT should have been able to get 5.6 or 5.7

And yes I was refering to brake/torque launching. I dont do it but why cant you do above 2k? Iv held the bake and reved to 4k...but I havent launched like that ever so i dont know.

All in all, Im just sayin that most people over estimate the DIFFERENCE in the 6MT and 5AT. They may both be in mid 6s or mid 5s depending on where ur racing but i dont see how it would be 1/2 second difference like many imply

I had an old list and I've been looking for an up-to-date list like this... THANKS MAN!!


2004 G35C 6MT + Nav, Silverstone

 

after looking at all the numbers after my research..i agree the AT coupe probably can beat the RX-8 by a small margin...but just for you to know..i checked up many of the time on the link that you gave me...its not very consistant (they probably got the times with many difference sources)...so..its a good reference...but just to remind you its not worth comparing between different cars...

 

agreed...id say give or take 0.5sec on ever car

MotorTrend mag had a list of all 03 and 04 cars with times that im sure they ran themselves....but i dont have it, it was my friends...it has the Gcoupe at like 6.2 and i think the RX8 at 6.8 but this was 3weeks ago so i may be off

ya...i would think if its g35mt vs rx8 mt...its pretty easy to tell g35 owns...but...g35at..and rx8mt...i think it would be closer...on top of it...even if g35at wins at 0-60...doesn't necessary means would win the 0-100 or even 1/4 mile...since..rx8 really have some kick in high speed/rpm...advantage and disadvantage of rotary..i guess =)
