Loose Hi
Thanks I understand now. Makes sense. I was planning a TC upgrade for my 1998 Z28 A4, but I think I will do the gears first. This will give me more TC options latter.
I do have anouther question. I have a friend that will sell me a new B&M Hole Shot 2000 for cheep ($200 CND). I assume this will raise my stall about 400 to 500 RPM. Of course, after buying it and payng for an install and new fluid, it will still be several hundred dollars. Do you think it is worth the effort, or should I put the money towards headers?
JA

ANYTHING IS STREETABLEHell I drove a trex 244/249 109.5 lsa around with a spool with a stalled auto in my daily driver. I guess what I ment to say is for street use (using street tires) the 4000 stall is a little high. Alot of what determins drivablity is the STR ... not the stall speed.

3000-3200 is super street friendly and you'll hardly notice anything different until you punch it.
3400-3600 is street friendly and the most popular stall size for stock motors and daily drivers. You'll feel a little looseness and it'll take a few weeks to get used to, but then it'll feel stock.
3800-4000 is streetable to some and too much for others. This is where people decide what they can and can not stand as far as stoplight to stoplight driving.
If you stay with stock gears then go with a 3500 stall. If you upgrade to 3.73's then a 3800 or 4000 stall with a 2.7 STR should feel pretty good if you don't mind a little looseness.
Hope this helps and good luck

This pretty well explains it !

Even with a H&C plus a 4200 stall, my mileage never went that low, except maybe during a real cold snap in winter where there was a long warm up period.
