Default About average E.T?

My 1999 Z28/A4(2.73) w/MTI lid, smooth bellows, and SLP LM1 just ran a 13.52/105mph. Does that sound decent?

Not bad, the gears are what is killing some of the time. Swapping them and a converter would net you 12s with traction.

Default How much faster?

I am already planning on installing 3.73's. How much will they lower my E.T. on average?

If you can hook, there is 2-4 tenths in gears.

Sounds about right. I also have a 1999 Z28 with A4. It originally had 3.23 gears and it usually around 13.50 or13.60 when it was bone stock -- a little better or a little worse depending on weather.

Not bad at all. I had a 1998 TA with 2.73's and ran 13.98 sec @ 102.5 mph. You did better than I did

why does everyone go for the gears first?

i'd pop for a converter before gears - but i guess that is a little more expensive.

I'd like to see your 60. Might have a little more in it. I got a 13.46 with a 2.0 in my 1998, so it's a good baseline.


How about doing a full exhaust next? I'm either going that direction or 3.42s, and save the stall for a little bit later.
