Stalled A6 cmon in
Fellas I want to add a little more pep to my 08 coupe. I currently have lg headers, borla stinger and halltech cai. I have the 2.56 rear with no plans on swapping it out unless I get a crazy deal on a z06 rear. Long term plans will be a centri style blower. What stall would recommend for me? If you have before and after results please list as much info as possible. Thanks!

I'm running an FTI 3600 with a Z06 rear and it made the car a total beast. I haven't even bothered to try to do any 1/8 or 0-60mph times as yet, because with the stock Runflats, 1st and 2nd gears are practically useless for anything other than producing smoke.
Based on my experience, in my estimation any converter with a higher stall than say ~3200 rpm takes a bit of tuning to get the TCC lockup to work smoothly so that it feels like stock, but it is doable. I'm nearly there now.
A couple of things to remember is that with the higher 2.56 ratio, the same converter will stall higher than with a lower 3.42 and the same goes for adding FI, so you will want to factor that in.
Also bear in mind that each manufacturers advertised stall could be different and you should talk to them directly before buying a converter. In other words, one brand's 3600 could stall 4000+ rpm in your car, whereas another's might only stall 3200.
My guess would be that the best overall converter for your long term use would be something with an actual stall of around 3200 rpm. A good converter will definitely wake your car up.

Adding more pep means you must have some currently, but it's only a guess as to how much. A higher stall doesn't increase power, nor does a Z06 rear gear that you may or may not get. They both just change the power range in relationship to the car speed. Going to FI can change everything.
There are too many unknown factors to consider to even take a guess.
How about you start by mentioning how you intend to use the car and a timeline for those long term plans. These will be the same questions the installer and/or the manufacturer will, or should, ask.

All of the other brands you've mentioned have loyal customers too and I've run both Vig and Yank before with good results. To each his own.

i got a fti 3200 billet converter. they built it for my car with a cam and 200 hit. i have a 08 with 2.56 gears aswell. i love the way the car drives now. its still like stock with a huge cam and its got the extra ummpp when u need it. i wish i had went a touch looser but the car drives so good i dont want to bother it and get it restalled. my car has been 10.08 on a 150 shot. but if ur for sure getting a blower get a stall for it. but if ur unsure then id get one buit for ur car as it is. 3600 stall would be ideal to me. if u want performance. who ever u get it from gonna ask u a bunch of questions so. figure out what u want to do for sure. thats a good chunk of money to be unsure and have to redo. if u want a max performance for the track 4000 stall will be probably what u want . if u want a more of a dd car with a bit of a stall 3200 . thats with the mods u got. 3600 is best of both if u ask me. but a blower im not really sure .

Any given converter will stall higher in a heavier car or one with more power, particularly more low end power or one with a higher rear end gear ratio.
Therefore, if you get the stall optimised for a stock car and then add a supercharger, the same convereter will stall higher, simply because it is a fluid coupling.
The term looser comes from the feeling that you experience with a high stall converter. You have to give it more gas to move the car.
A higher stall usually provides a quicker launch, unless the converter is too loose and stalls well above your torque peak.
But there's more to consider than just off the line performance. You want a converter that gives you the best balance of performance and driveability.
The magical thing is not getting a conveter that is so loose that it becomes a nuisance to drive the car.
Think about approaching it like you would approach women, looser ones can be more fun, but do you want to live with that every day?

..........also remember! Just as a loose women can be dressed like a Princess, a trans tune can overcome a lot of the iniquities.
BTW! I'm running 9* overlap in my stock stall with the 2.73 gear. It commands my full attention on the street. :-)

Ive had both a yank ss3600 and ss4000 on my cam/bolt on ls3 and have no problem daily driving the car. The 3600 wasnt bad at all around town it just didnt 60' like i wanted. The 4000 is looser but i was willing to take that in exchange for a better launch. Best 60' with the 3600 was a 1.65 and for the 4000 its a 1.46. Id say 3600 for best if both worlds.
