Would could i expect to see for a gain in the 1/8 mile when going from 2.73's to 3.73's. Or should I just do a stall??

 

Yes but not a whole lot. I would stall it before the gears. Bolt-on A4 cars are capable of low 12's, high 11's in the 1/4 with a stall. Gears alone will not get you there.

 

wow I'm surprised no one else has data. BTW thanks junior for reply.

 

i gained 3 tenths in the 1/8 form going with 2.73 to 3.42 other than that i was bone stock if thats any help.

 

that's what I'm looking for... I would be happy to gain 3 tenths! Cool,,,thanks!

 

U have to start with the gears first then the stall i gained 4 tenths going with the 373's and headers

 

Since your unlucky and have the 2.73's I'd change the gears with the converter. Of course, tire diameter and all that other stuff comes into play as well. There are plenty of threads, and even stickies about this if I am correct. Good luck.

 

you need to get gears and a converter at the same time! your converter needs to match your gears! you should pick up quite a bit tho
