Man im running 4.33s in a 6 speed car, and have been racing sticks for years. Like i said i have gone 1.7 60s plenty of times on slicks. In an auto car with stall and gears and stickies, that kind of launch is cake, but its not something most m6 guys do often. The autos are faster off the line, 6 speeds are faster after you get moving

If you guys want to argue the A4 vs the M6 factory stock, I have the answer for you. Before I did any modding to my M6 94 Z28, I raced my buddy with an A4 94 Formula. I'm an excellent stick driver and have almost exclusively driven stick all my life. I beat him pretty bad, at least 3 car lengths at 100. The trick to driving a manual is to NOT spin and NOT bog it down. If you can do that, you'll beat an auto, street tires or drag radials, every time. Assuming that they auto doesn't have a higher stall, it's easy as can be, but you need to know how to drive. It's not mash gas, pop clutch. That's how you do burnouts, not launches. Once you get into higher stalls, it's a much harder thing to do. I've still managed to beat (this is on the street with street tires) another buddy with a 95 Z28 that had 3000 stall. He still had the 2.73 gear, though, so a higher gear might have made the difference. It wasn't much, maybe half a car to a car, and we had similiar mods. I still agree that the auto is more consistant, especially for those you go to the track. There is nothing more I hate than accidently missing a shift (very rare, especially with my Pro 5.0, but it still does happen).

from the factory, the M6 wins in the 1/4; on a typical stoplight race which is usually much shorter, the A4 has the edge but not by much. but it is true for stock cars only.

btw, have you noticed that all real fast drag race cars are automatic?

Old TQ 376...no dyno since heads/cam/headers.

New setup is consistent 1.9's on street tires (3200 stall)...gotta love the Pep Boys Futura's

I'm having the same dilemma.....4L60E is toast so the debate is on between a T56, 400 or 200-r.

IMO...it's your personal preference. I love the auto for the consistency at the track, stall and being easier on the rear.

But I really miss a manual and if you can powershift well, you won't see any of the lost time on shifts.

They both have their pro's and con's....go with what you want. Me, I'll most likely go with the T56.

If your going to run on the street go with the 6-speed. With 4.11 gears they rock. If you want to serious bracket race (one race a week or more) then go with the auto. Its hard to win with a stick against the hard core racers. Yea, I know how to drive a stick. I ran my car for 3 years with the stick and just converted to an auto this season. My 60' times are about the same however, I lost .2 and 5mph with the auto but I'm a lot more consistant. The auto is easier on parts especially when you make 500+ runs a season. Last season I had the only stick out of 150 points racers.

Very true...at a stoplight race anything can and does happen...I would say in situations of 0-end of first gear the auto may have a slight advantage on the street...however...if you're good at driving a stick any problems you encounter you should be able to adjust to...too much wheel spin...bogging the motor things like that...if you're on your game all conditions equal the 6 speed will win each and everytime...some of you said the truly fast cars run auto's thats not true look at taner, he's got a believe a 95Z28 and runs the 6 speed he runs deep 9's. Also for those who say its impossible to shift faster then an auto it depends on the transmission...to fully complete a shift a modded 4L60E takes .35ish or so seconds a stock one is about .5 seconds to fully engage the gears...a good manual driver can do it in .15 to .25 seconds depending on the length of the throws clutch travel and things of that nature...in an F body you can pull off shifts in the .30 range easily and as quick as .22 if your able to shift like a pro and I do mean like a pro. An article I read in CHP several years ago had timing for various drivers/tranny combos and shifting. Fastest that a pro race driver did in an F body with the factory shifter/tranny was .22 seconds. The magazine guys were clicking off .25-.30's all day. Its not that hard if you drive it like you stole it.

I thought that Taner was going thru those trannys often?

On the street, a guy with an auto, stall and tires is going to lay smack easier than a guy with a manual....and not really worry about blowing something up.

Most of them fast drag cars that are automatic are very diffrent then ours this will make another point to people saying how you can choice the rpm you shift in a standard and you cant in a automatic this isnt true, Most of those automatics are Full manual valve body, meaning you have to shift the gears yourself because they wont shift on there own anymore.

I don't know how many tranny's he's been through so I honestly can't comment on that...as for blowing something up you do know that auto tranny's go out? Fail to shift? and can also cause things to "blow up"? There are many things that can cause problems on an auto car just as there are many things that cause problems on standards as well...

I like how the auto pulls off the line(good for the 1/4 mile)

The only problem for my car is the traction off the line

BIG WRONG... if you take to of the same cars... same mods, same weight, same everything... besides one has an m6 & other A4 (w/ a 3200 stall) my money would be on the auto... with a stall the motor will always be in its powerband

if we have the same tires DR of course. i got news for you yes the a4 may pull a quicker short time. but i will make it up after that. that stall never locks up unles you tell it to. ive raced a ls1 with a 2200 stall off the line, we were both on street tires and i left him by 2 car lengths of the line. his tires went up in smoke. so that goes to show you that its the driver that counts.

yes a a4 with a stall will stay near the powerband, i say near becuase when it shifts it drops father out of that powerband but when a m6 is shifted it doesnt drop as far out of the powerband. so im closer to peak power than you are. but in truth thats not going to make that much difference.
