As long as you win, you're faster. All of the loyal granny tranny owners who keep saying the 5AT is faster, have you ever been to a 1/4 mile track and raced other G35's? Have you ever been to a dyno day with other G's?

I've raced G35Sean's 5AT Crawford Package G35 with m Crawford Package 6MT G35 and heavier wheels/tires and I beat him by 0.1 seconds on EVERY RUN.

 

I dont know about speed of shifting, but my understanding is that the "firmware" is different - you can asked GurgenPB (he has a sedan). The 03 and 04 sedans at least supposedly operate differently. Here is how it works in my coupe - you tell me if it's different in your sedan:

When in MM mode and accelerating from a stop, you can upshift at the desired RPM. It will go from 1 to 2 to 3 to 4 to 5. If you coast to a stop, it will automatically drop gears for you. It will never automatically upshift for you. If you floor it after stopping, you will be in 1st gear and RPMs will sky rocket and you will hit the rev limiter unless you upshift. You can downshift or double downshift at any point (the latter does not work when you initially go from D to MM mode though as there is an initial downshift that must first complete).

The MM mode provides all of the control of a MT with the exception of being able to slip the clutch and drop into neutral (can't do that easily with AT in MM mode - have to go back to D and then up to N).

With the 10 wire GroundingGear kit, shifts are immediate and very responsive in MM mode. I was disappointed with MM shifting because of the lag until I got the GG kit.

And I'd say the AT/MT issue is irrelevant. Pulling an inch or two ahead is not "smoking". The difference in RWHP from car to car (stock) is probably just about as significant as the difference in performance due to AT/MT (IMHO). But then I consider 10 RWHP difference "minimal". Now 50 or 100 means something! No stock MT is going to take g8tor's beast! (eh, g8tor?)

 

I can't believe the comments being made on this thread...

03/04s out perform 05s...they may perform similarly, but out perform, what the f**k is this guy/girl talking about

i've seen stock 05s clock in at 14 flat

and g's performing better after they're broken in...isn't that ovbious?
most machines perform better after they're broken in.

the 5at has more items that need to be broken in such as the tranny (well more so than the 6mt)

but again, how does this have anything to do with what were talking about

 

Ummm, I think he was just joking around... Let me sum up this thread for everybody: the performance of all stock G35 cars are about the same. Sweet and simple. Everybody happy?

[Ok, for you picky people, I define "about the same" as within a "few" tenths of a second of each other (0-60 mph or 1/4 mile).]

 

To illistrate, lets say that a BMW 330 gets a slight jump on a G
The BMW would likely reach 20 or 30 MPH before the G. The G would then begin to make up ground likely reaching 60 MPH before the BMW. Now while the G may be at 60MPH and the BMW is at perhaps 55MPH, the G is moving at a faster speed but is playing catch up to the BMW.

There are some 0-60 breakdowns on the web that you might look at for similar performing cars. You will likely notice that oftentimes while car a may reach 30 MPH more quickly, car B may reach 60 more quickly. Thus somewhere aroung 45MPH car B would likely be playing catch up to car A.

You might also reference trap speeds and how often we see slower trap speeds but faster 1/4 miles.
Check out the following link for example:
http://automobilemag.com/test_data//index1.html
Look at the Ford Mustang GT and the Jag s-Type although they both reached the 1/4 mile at the same time they did so at different speeds. Same goes for the Jag XKR and the Honda S2K- they both reached the quarter mile at the same time but each at different speeds. Thus the one going faster was likely playing catchup before reaching the quarter mile. If you look at the various results, you will likely see may examples of the same to varying degrees.

It's kinda like merging on the freeway, you may be moving at a faster pace than the traffic in front of you but they got the jump. Thus it is impropper equate 0-60 to distance traveled.

As regards breakin- the reason why this is mentioned is because the cars are tested pre breakin. The 5AT's ECU is alot more restrictive during breakin- thus the pre-breakin indicate more drastic differecnes in acceleration than after breakin with an ECU reset.

 

I wouldn't go that far bro but the difference is not overwhelming as some may say. Especially considering some of the vids posted that show a 5AT and 6MT going against each other. In the first race the 6MT won but really didn't pull had until @ 3rd gear. The 5AT had some heavy aftermarket wheels on it as well. In the second vid, the 5AT had just a spacer installed and beat the 6MT.

 

lawd! ....dimentia is a terrible thing!

 

I'm talking about differences that i notice ...when i drive a loaner sedan.... some one started a thread... I say its different because ... u can upshift to 2nd gear in MM on a sedan .. where as a coupe doesnt let you do that ... i've also noticed that the sedan have more lag than the coupe does.. for some reason .. and i have an 04 and and i am talkin about the 03/04's ... i would not know about the 05's.

 

You're probably not really in 2nd gear on that loaner, even though it says M2. The early sedan's MM mode was just a top gear selector, not a true gear selector like on the coupes.

But those sedan loaners always seem to have extremely strong low-mid range pull.

 

So you're talking about your perception and not the actual function of the car...

I thought so.

What do you mean you can "upshift to 2nd gear in MM in a sedan but not the coupe? Of COURSE the coupe lets you upshift to 2nd in MM. This makes no sense.

 

EXACTLY!

Brilliant post. You hit the nail directly on the head. This is EXACTLY as my sedan performs.

Thanks for clearing this portion of the discussion up.

 

That's how the coupe and the later sedan MM worked. The earlier sedans were just top gear selectors. If you compared to other MM modes out there, it's one of the better ones. It's one of the few where the MM mode is faster than the D mode (D mode shifts too early 1->2). Unlike the Acura TL, it won't upshift into 2nd gear automatically.

The upshift does take too long though. If this pans out, we'll be in luck:
SGP VB

Per Gurgen's data, it takes about 0.5 to 0.6 seconds for an upshift stock. With the Valve body, you're down to about 0.2 seconds. Per BMW, the SMGII shifts from as fast as 0.08s to about 0.250s.

The sedan has a 5AT and the coupe a 6MT. My sedan is a 2003.5. That was my first run ever and I belive Ed_C's coupe is a 2004. I had only a plenum and pulley then plus the injen intake. I actually squeeled on the shift to 3rd. Ed had some mods but not as many. His car has 280 hp stock and an extra gear so I won't make apologies for him but will concede that the last time we raced he owned me but has way more mods than me now including everything I have plus the TS ECU flash.

Maybe the granny tranny is the one to have after all - eh neff. Especially for those folks putting in 8000 buks in FI sytems when the MT clutch can barely handle the power stock. I notice most AT's aren't the ones in the shop with tranny's grinding either. I know what I'd be willing to take my chances with if I was kissing my warranty good-bye!

 

Time to put up or shut up. Let's see some times for the 6MTs and 5ATs. I think you 6MT guys will be amazed at how close it really is. Also keep in mind the mags correct all their times to sea level and standard condtions.

My 03 sedan 5AT with a Z-pipe did 14.49@97.59mph in conditions equal to about 1900' above sea level (calculated density altitude). If I was a ricer, editor of a magazine, or a guy that "ran at LACR", my corrected times for sea level would be ~14.1@99mph.

I don't doubt the 6MT is the faster machine in the right hands, but I can tell that after racing the 1/4 mile for about 12 years now, the "right hands" are far and few between.

 

I mean't u can upshift to 2nd gear while your at a stop in a SEDAN, where as on a coupe you can't do that..
