I have an A4 tranny with 4.11 gears, i was in 4th at 5 grand and i was almost maxin out the engine , i wus doin prolly like 130's i think i dont know, becuase my speedometer was never calibrated to the gears. Does anyone know what the top speed of a 94 LT1 z28 with a A4 and 4.11's is ? and wha speed i was prolly doing at that rpm (5 k in 4th). lol it looked crazy becuase my speedo was dumped completely.
I want to change them because i dont go to teh track really so it dosnet serve me any purpose havin them. I want punch off the line and good top end . should i go with 3.42's or 3.73's does any one no there top speeds on a4's?
Thanks guys with the gears im clueless , i appreciate any input.

Well I can't remember what OD was so I put it at .7, this is also with 26" tall tires. At 5000 you were going approx. 134 mph. Top speed saying you wrap around 6200 rpm's would be approx 167 mph.

3.73s is the common gear of choice w/an auto car. They allow you to get maximum rpm out of your car w/o having to shift into 4th at the track. o/d is not a gear you want to be flooring the car in because it can break the tranny very easy. So yea I say switch the gears out to 3.73s.

I punched in some of your #'s and there was no way you were going 130 with gears that big. Your speedometer is definitly off, like you said.

No my speedometer was dumped beyond 150. i raced a 350 z tonight and i was doing about 120 becuase my cousin hit his speedlimiter behind me and i kept going racin the 350 z, and i wasnt near 5 grand then... lol my speedo is def off i know that but i wen i hit 5 k the other nite my speedo wus completely dumped. lets just say wen it says 90 im doin really 60.
