I have 2000 A4 I just pulled a 13.78 at 102mph here in El Paso. this was on crappy dunlop tires. I know i should not have gotten gears first. I know I can snap the rear end. But I need honest answers. I am installing ssf 3500 converter and I currently have 4.10 gears. lets say I did have some drag radials. w/o thinking about the rear end snapping will my times be at its best or do u guys think my times could be even better if I dropped my gear ratio to a 3.73. what about dropping back down to 3.23 w/ converter while my times be worse

I leave in el paso tx. I have been told that altitude here is about 5000ft maybe a little less or more. mods are Short egr, fernco bello, slp lid, k&n, cutout, gutted cats, diablo programmer and resistor on Iat since daily temps are 100 degrees 4.10 gears. part sitting at home:ssf3500 trans pak and trans cooler

 

without slicks those 4.10's will be downright impossible to manage.

i'd rather have 3.23's over 4.10's any day. the bigger the verter the more torque you launch with, so you might not break the rear end with 4.10's but you will suffer on tirespin unless you are running all out slicks then i'd question the 4.10's.

 

323's all da way
