DD stall questions?

DD stall questions?
Here is my situation. I am going to be running a loud exhaust: LT's, h/x-pipe, dumped with bullets. It is my DD and here is the big issue. I want a stall for performance, but don't want high rpm cruising speeds under daily driving because it will probably have annoying drone at over 2500rpm. Does that mean I shouldn't by a converter with more than a 2500/2600rpm stall? I am new to how stalls and shift points under normal driving conditions work. I am looking for loud/bad *** sound first and am planning a cam in the future so if my situation will only work with a 2600stall, I may pass on it and do a baby cam with full bolt-ons and possibly heads for the future. I researched that an ideal DD stall is from 3000-3600rpm, but I don't know how many of those people are running dumped cat-less true duals. Ideas and info greatly appreciated. I couldn't find any answers to this from searching.

LS1 converters are a lock-up style, so once you reach highway speeds and it locks, the RPM's will drop down and it won't be so bad. It's accelerating that will be annoying with a loud exhaust and a converter. A loud exhaust will make a small converter "feel" big if that makes sense.
On that note, don't waste your time with a 2600 stall. I'd look into a 3600 or bigger. Yank has the SS series which are nice and tight for daily driving, yet offer great performance. The SS3600 and SS4000 are very popular converters, and they are deceiving in that they don't feel like their rated stall speed. I ran the SS4000 and it was really a nice driving converter...very tight, even with 3.23's. You might give them a call and see what they recommend. By going with a 3600+, it'll leave you room to grow, especially since a cam is in your future. Good luck!

I DD a Yank SS3600 and it is a tight stall but don't ever believe the guy who says "it drives like stock". You will give up a little softness on the bottom to make your car go like you never imagined it could on top. You just got to figure out what you want. I love my SS and will never look back..

So shifting rpm is decided by amount of gas still, but it takes a bit more than stock gas w/a higher stall converter to get a car moving.
How much? And is yank the series that undervalues their stall rpm by 2-400?

Yes, it'll take more gas to move, but not the rated stall speed. A lot of folks think that a 4400 stall will take 4400 RPM's to move when that's just not the case. My PT4400 will accelerate with traffic at 2500 RPM's. This is with stock 3.23's. It'll accelerate at a slow pace with as little as 1500 RPM's. Obviously, the more throttle input, the more acceleration. My converter is definitely on the looser end so most other converters won't take as much input to achieve the same result. My previous SS4000 would accelerate with traffic at ~2200 RPM's.

3600 is the stall of choice for most as a DD. Most of our customers say they drive virtualy stock till they nail it but each persons defination of stock can vary. Of course it is not stock but like SOMBITCH said they will run on top.Excellent choice for DD.

I have a PT4400 with a T-Rex cam, and it's dumped into a bullet muffler. I'm used to it, but that's just me.

Vigs are slightly underrated. Yanks are pretty much spot on.
Yes, it'll take more gas to move, but not the rated stall speed. A lot of folks think that a 4400 stall will take 4400 RPM's to move when that's just not the case. My PT4400 will accelerate with traffic at 2500 RPM's. This is with stock 3.23's. It'll accelerate at a slow pace with as little as 1500 RPM's.

My previous SS4000 would accelerate with traffic at ~2200 RPM's.

Yes, 2500 will keep me with traffic no problem. 2800 IMO is starting to get up there. Once I finally get my 9", the 3.89's should tighten things up nicely. For a 4400 stall speed, it's really very streetable. This is a video that kind of shows normal driving for me.

x2 best way to summarize it.
i would say any stall above 2800 will require about 2,000rpm to keep up with traffic slowly if not more. thats if you want to drive like a grandma everywhere. i usually have to keep it around 2,600 to drive how I like to from a stop. keeping my momentum requires about 1900 rpm on a flat road. the car moves with only like 1300 rpm but barely.

No. My intent wasn't necessarily to show the tach, although I can assure you it is right at or below 2500 RPM's. On top of that, I wasn't filming...I was driving. My intent was to just get a feel for normal driving. You can't even see the speedo that well. My buddy did the filming and all the posting, so I got what I got. I specifically stated that it kind of shows normal driving for me....which it does. Deal with it .

There is a crappy video of my Vig 3600 in my Semi DD GTO cruising around and a split second of WOT, everybody says Vig's are a lot looser then what their rated stall speed is too.
