...I would ONLY consider a multi disc in a car with a forged bottom end and crazy boost from a blower or turbos or a 250 shot or higher.

Converter question - Single or Multi Disc
I'm in the process of purchasing a converter for my 07 A6, and I was wondering if a multi disc setup is necessary or will a single disc work fine.
I spoke with Jack at Precision and he said a lot of the nitrous/boost cars use a multi disc so it will lockup at WOT. My car has a 100 shot installed but I don't plan on going much higher than a 125.
What do you guys recommend? Single or multi? Pros and Cons of each?
Any input will be greatly appreciated.
Thanks!

Somebody with knowledge answer this guy. And enlighten me.
I'm confused, I thought that only clutches for a manual transmission were single or multi disc and torque converters for an automatic transmission just came in different stall speeds and a choice of lock-up or non lock-up.

they always try to sell the multi disk, i have a single disk from them, it wont lockup on the dyno, but on the street it is fine, the multi disk is slower in the 1/4 by a tenth. if you roll race top speed with juice then you might want it, but with the a6 you don't need it unless you get 410s for the 1/4 and use all 6 gears, then once your in 6th command converter lockup

I've got a single disc 3600 stall from Yank and pulled a 1.569 60ft three weeks ago. Dave told me the same thing - that you don't need a multi-disc unless you've got a blower or significantly more power than stock.

single disc would be fine for you. A4/A6s only benefit from the higher dollar multi-disc stalls if its behind a LOT of power. If your just a 'normal' stockish or small shot C6, go single.
If you wanted to eventually go with a big cube stroker on a much larger shot or run a some serious boost on a turbo/blower set-up then a multi might be worth it for you.

The 2009 CTS-V with the LSA 556 HP supercharged 6.2 L engine will be available with a 6 speed automatic. It's the 6L90 and it has a multi disc lock up torque converter...sounds like GM agrees with you guys.
