I am currently tyring to make up my mind wherther or not i am going to stay with my auto or switch to a T56. I like the way the A4 gets off the line so fast. It just hooks and goes like hell? Is a M6 the same way? I know the autos will almost always be faster in the quarter mile.
How much do you think i would loose?


also really and trully on a scale from 1-10 what would you rate the install as? It looks like i would be drilling three holes then making the hole for the shifter. I have heard the hole for for the master cylinder is just pluged in the firewall behind the plastic. Then do a little wirring. Doesn't really seem that much harder than just doing a tranny removal/instalation.

Thanks

lots! the M6 is way way way slower off the line.

I went from A4-2800stall-3.73 gears to M6 3.73 gears and the car feels like a snail off the line; however, once you reach 3rd, it pulls much harder.

with the A4 setup I beat many cars that had more power, but on the highway, forget about it the M6 would beat me easy

 

You'll get a lot of contraversy on the boards on this question i myself think that the auto is way better for the 1/4 then the m6, i say get a street/strip 4l60e built and go from there

 

still looking for more opinions

thanks

If you know how to drive a manual well, and learn how to launch it right, you shouldn't lose much if any low end. Even with the stock 3.42's behind an M6 car, the final drive ratio in 1st gear is slightly steeper in the M6 as oppossed to a 3.23 auto. Plus the M6's are close ratio so you don't lose rpms with each shift as much as the A4. If you're worried that much about low end, just get a Moser 12 bolt and put at least 3.73's, preferably 4.10's, good nitto's, and a strong clutch and you'll be good to go.

lol....umm u dont lose any low end
Learn to drive a manual

 

Stick is the way to go baby... I wouldn't trade mine for anything. I like being in full control of the car. And you can hang gears around a corner and not wait for it downshift just punch and it and skirt out hehe. Learn how to drive it and launch it right and you will be set, I mean the 2 extra gears and better ratios more than make up for the "auto-off-the-line-rookie-advantage"

 

It's not that i don't know how to drive or launch a stick. I own 4 cars and this is the only one thats auto. It's just that when you put 3.73 or higher gears in a M6 you do a lot of switching gears by the end of the quarter mile. Switching gears takes up time no mater how good you are. Not to mention the whole launching part of the equation. I mean look at the facts 9 times out of 10 a auto car will be faster.

I however don't take my car to the track that much anymore. It is mostly just a street toy. I wan't the reliabilty of the M6 mostly. It may be a little more fun on the street also. If i had $4000 i would build me a monster 4l60E but i don't so i guess i will go with the M6. Just trying to figure how much of a whole shot i will be giving up.

Thanks

You really don't lose low end, what you lose is the ability to mash the gas as hard without spinning the tires. Learn how to feather the throttle and get a feel for the car and you'll be launching hard in no time.

 

Just out of curiousity, isn't there something in the computer that you have to change or compensate for when you do this kind of swap? If your car is a dog out of the hole, then maybe this is part of your problem? My M6 does just fine out of the hole with 3.73 gears (although I am switching to 4.11's).

 

I disagree with lots of the posts here. I've met lots of self-proclamed good stick driver; However I have not seen a single one stay even close to the car on launch when I had the A4-2800stall-3.73 combo. The A4 would consistently launch much harder and always be ahead in the first half of the race; after that, the outcome would mostly depend on power and how much of a gap I could put in the first half.
I don't claim to be good stick shift driver, but I could never get even close to the launches I had with the A4.
just for the record, I broke 6 A4 so I switched to a M6

 

first off im not going to say either one is better. but if you can learn to launch a m6 you can plant more power to ground. you do not loose power at all. but i will say that a4 is more consitant. and they are easier on the rearend. but if you learn to drive you will love it. if you have a car you race every week end i would put a good built a4 in it and be more consistant.

and as far as the people saying that a4 shifts faster. thats crap if know how to drive stick. i can shift just as fast as any a4. and we were out street racing this weekend (and im not talking 20 mph to 45 mph im talking 25mph to 100mph) so i went through all the gears as i would at the track. we vidoed a couple of the races from inside the car, and i have watched the vidoe and listen to the shifts and i can shift just as fast. after i raced one guy we stopped and talked and he asked me how i shift that fast and pionted out that he was not gaining any ground at all between my shifts. and he said he could hear the shift because he had stock gears and i had the 4.10s and we were shifting at different times so he could hear how fast i shifted. but there is always that dreded chance of a miss shift in a m6, but there always that dreded chance that your a4 wont shift.

but if your willing to really learn how to drive a stick its more fun but it is harder to launch. and not trying to get into the old debate but it is more of a dependable tranny that the 4l60e. but do whats good for you.

 

I don't see how this is physically possible; Even if your coordination hand / foot was perfect (nobody does) and you were moving as fast as a high pressure hydraulic system can push parts (no chance in hell), the amount of travel you have to do with the shifter, that the clutch does, etc is higher than the space you need to close between the clucth disks, in a A4, when they need to be engaged.
as an example: compare youself pushing something for 2 inches to a machine that has much more power than you moving the same thing 0.2 inches; who would win?

 

you wouldnt loose any power..if any you'd gain some, its just alot easier to extract the power down low in a auto

 

Its simple. If you like to road race then use a 6spd. If you drag race keep the auto and build it up real nice. I don't care what kinda superman you think you are YOUR not shiftin faster then an auto! Imagine your sitin at a light and someone catches you off guard , 6spd you will end up spining bad and not catching them.
Spining sucks thats why I love autos.
