new to A4s need advice My other two LS1s are M6s, and I think I want to buy an A4 this time. The car: 2001-2002 WS6 t-top or vert(can't decide), will have a head/cam package and I want a stall converter. Something to really help the car. I don't want a stall thats gonna kill my fuel mileage though and tear up my trans. I was thinking a 2500-3000rpm stall. Yank or Precision? What gears should I get in the rear? Or keep the 3.23s? These A4s are so damn confusing.
Re: new to A4s need advice Vig 3200 <img src="gr_grin.gif" border="0"> it stalls at 3800, but I've never heard anyone complain about it not being streetable or sucking up gas.
As far as gears, with H/C you're going to want to go w/ 3.73's to move you into the powerband down the 1/4. You should stay w/ the 3.23's at first though to see what they do for ya. <img src="gr_stretch.gif" border="0">

Re: new to A4s need advice Don’t waste your time on a 2500/3000 stall. Get 3500 or bigger. However, on a heads cam car, a ‘verter rated at 3000 stall will probably stall more like 3500+ anyway.
Re: new to A4s need advice RPM WS6,
Not true. A stock displacement heads cam car will change the rated stall very little over stock. Most h/c motors make more torque above 4000 rpms over stock, but below they're not much stronger. It's the 2500-4000 rpm torque reading that determines the stall of a converter. A 422 makes a lot more torque at 2500-4000 rpms...that's why it makes a converter stall more, but a h/c cam motor won't hardly affect the stall at all unless you get a 4000+ stall converter.

Re: new to A4s need advice Patrick, thanks for the explanation. I guess I was thinking more towards guys already running 4000+ stalls gaining extra stall with heads/cam. <img src="gr_stretch.gif" border="0">

Re: new to A4s need advice I'm extremely pleased with my YANK ST3500. It's seriously the best $1,000 ever spent in my opinion. I went from a 13.8 to a 13.0 and the 60' went from 2.1 to 1.7 on Drag Radials. Mine is also a daily driver and gas mileage was noticeably hurt, but not much. Depends on how you drive, I haven't gotten a whole tank of gas where I haven't been racing the snot out of it half the time - yes a converter will bring out the little bit of John Force in each of us.
