I noticed a difference in top end pull between the ss4000 and pt4400, pt4400 is better imo. I havent got the pt4400 to fully hook up but I dont its going to 60 as good as the ss4000 mod for mod.
check out larry's post he has tried all 3 ss4000, pt4000 and pt4400...he now has the ss4000 back in his car...
name is LS1 Speed, he is a sponsor from speed inc..., great guy to deal with too

I'm not sure what you guys are talking about as far as top end inefficiency, I guess I have never heard that. My H/C car traps 119mph on the big end and cuts low 1.5 60's how can you beat that? except for spraying it
there are only a few that are even on the list after 06...i think the ss4000 just debuted around that time...both are great converters i am not getting into this battle again...
take a real good look at the list again and the 60ft times...some of it is from the cam the rest is from the converter...cause it isnt from my 3.23 STOCK gears ...
buy what you want...jm-jr is pulling 1.31s after switching from a pt4400 to a circle d...there are plenty of great converter companies out there, i like the SS line and yank because it has proven to me what it can do...
take it all in and weed through all the shit and make an educated decision on what you think it best...

Don't know about other peoples combos, but my SS3600 seems to be pretty efficient on the top end, either NA or on the bottle. Then again, it's just another lowly LT1.

what the hell does it matter what is powering it...so now the trans knows the difference between and ls1 and ls2 and lt1...
he tried the same 3 converters in the same car...
it is fine with me if everyone doesnt want to run the ss4000, i could careless either way...run whatever you want...
the SS line has been good to me 116mph SI without an electric waterpump, stock gears, ls6 intake, bouncing off the limiter, and stock tune, no dyno tuning was done, just shift points...and 3365 Raceweight...yes the DA was -800 but not -2k like atco, i would kill for that...
rant off...

I would probably recommend the SS4000, but results from a radically different motor are retarded.
Does the trans know the difference, I don't know. But for an engine that makes peak torque 2000rpms earlier in stock form and who knows what his 396 LT1 is doing, that could make a fucking huge difference in stall characteristics. Something that makes huge torque and makes it down low doesn't need (or usually like) a bigger, looser stall.
If I build a stoked LT1 and find out that a B&M converter is better than a comparable TCI, which one would you say was better for a near stock LS1? Who knows and who cares.

the point was apples to apples test on the same motor and tran...just like if a 408 runs a test on three different lids, will you get the same gains, most likely not but the information is still useful...

Lids aren't stalls. Stalls are stalls. If a 408 runs better with a different stall, it doesn't really matter to someone with a 346. More tq, more power, more rpm? everything about the stall and how it works is effected.

yeah that may be true but he is close to the same power 127mph is the same as my dads car...only thing that might be slightly higher is tq...stall cover a larger range than you think...stock power to h/c/i power is alot different...but the same converter can work great for both being 10mph off...
to each his own, i only brought it up cause his car make around the same power...

Since your dad took out his pt4400, why dont you try it?
why screw with a setup that works...i could careless to prove to everyone that the SS4000 is better...if you dont believe me that is fine, run what you want, maybe GOD touched my ss4000 too and it is the only one like it...
best my dad has been with heads, larger cam, and 100lbs lighter was a 1.36 at 127mph...i think he is going to pull some low 1.3s with this new circle d but only time will tell if they lossened it up enough...gotta log some runs (just autotap)

Another SS4000 user here. I don't even know this things potential yet, i can't find traction at all. I stepped it up from the SS3600 and the SS4000 is a much better converter. IDK what I am going to have to do to find traction with this thing, maybe some LCAs and relocation brackets or some M/Ts.

How high up in mph will it spin the tires? Or do you mean off the line traction?
, great guy to deal with too
