what size stall in a a4 car would net the same times in a m6 both exact same mods

know what im saying?
both cars have same mods, same 60ft, no traction problems

if a m6 can do 12.3
the a4 would need what size stall to match it.

stock wouldent, would it?

A stall isnt going to gain you much MPH (if any at all), and the majority of the benefit of a stall is going to be in the 60, so if yo're both 60ing the same then it will be pretty close before the stall. (a decent converter should drop you a good .2 in your 60)

The only other area the stall will really help is that in shifts if will drop you into a higher RPM.

thats what i prety much was thinking

so if i can launch at 4k to get 12.3
the a4 would need a 4k stall to get that 12.3, and if it was the stock stall it might only do 12.6 ish???

ive seen stalls take off .6 on a member's et on here so with the stock stall the would've been closer to 12.9

85000000 million....wat gears? mods? tires? what is the 60'? weight?

You would not need a 4k stall to 60 as hard as a manual launching at 4K.

But yeah, we would need other factors...gear being a big one.

3400 stall i got a 12.4, went to a 4000 and got 12.1X's with 1.7 60's, took out the hot cam and put in a 226/228 cam and ported/milled lq9 heads and got a 11.71 with a non shifting tranny.. i'll take the auto, a buddy of mine with a larger cam and nitrous in his 6speed car has been struggling to keep up with me.

both full weight both 3,73's both 26" e/t streets both 60ft are 1.75

if teh m6 can do that by launching at XXXXrpm the a4 would need a XXXstall to do the same

Thats not quite how a stall works.
If you take a car with a 3500 stall it will launch harder than an M6 launching at 3500 and get a better 60.

Stalled Autos > M6 for drag racing.

so then what rpm stall would launch the same? stock?

FloydSummerOf68

iTrader: (1)

Thats not a question that can easily be answered
It depends on how the M6 is launching and how you are launching your stalled auto.

If you get a 3500 converter you will be hard pressed to find an M6 that can 60 better than you.
I'm not quite sure why you're interested in what would equal a manual. I would be more concerned with what you destroy a manual

But this is just generalizations...all cars are different and the optimum way to do it is to get a dyno and base your converter off of your dyno and then get the gears to maximize your RPMs when you pass the traps.

if teh m6 hooks a 1.8 from launching at 3k
what sall would not be able to do that as well

camaronut502

well i know for sure that a 3000 stall with m/t's can get high 1.6's with consistant 1.7's in a ss with just headers/lid/exhaust. with street tires he's seen a few 1.8's but most are 1.9's.

An auto with DR's and gear should be able to get close to that with stock stall.

When I had my stock converter I was getting high 1.9s in my V6 on street tires. A v8 with basic boltons and 4.10's should be able to do low 1.9's or high 1.8's on the stock converter (but I dont know for sure, seeing as how I dont race a V8...so someone else will have to chime in on that)

also how long are you wanting to launch side by side...bc m6 dumping at 5k would mayb get a 1.60 60' and an auto with a 3200 cut a 1.60 then the auto will pull away bc the m6 has to shift drop out of powerband ect...then the m6 will come back on the big end due to extra power to the ground bc of less drivetrain loss

stock converter here, waiting to buy a new one but on the stock converter with 4.10's and some MT DR's i cut consistent 1.8, i wanna get it lower but that will wait until the stall goes in

You cant even compare the two because the m6 has a clutch and he can bring it up xxxrpm and depending how he drops the clutch is how his car is gonna leave. With the auto trans will only stall up to whatever the converter stall speed. Thats why alotta guys
will say they wish they initially went bigger on the stall. But there is advantages to a stall like torque multiplication, and ther are some disadvantages like some greater drivetrain hp loss to wheels.

broken98

play with your t/a adjustments and expirement with tires you should be able to drop the 60s a little more along w/ stall. You will love the stall very good investment
