Thanks lemons ive been prowling youtube and looked at a couple ss with 3200 stalls and they pick up around 2000-2400 with traffic which i dont really have an issue with i mean i know a stall is gonna take more rpms to move i just dont wanna be turning 3k to get it rolling with traffic. I just assumed 3200-4000 would be a big jump andd therefore it would be a lot different down low but maybe i'm wrong? Anyway circle d and yank both specified a 3200-3600 converter I'm just trying to get feedback on which would be better for the gears in the back. A 3200 will get rid of most dead spots in the shifts going to about 4700 between shifts from what ive heard and a 3600 will kick *** from a roll while not being any real difference down low?
Thanks For the replies guys

A good 4000 converter is going to pick up around that.. Hell, my old 4400-4600 VIG picked up right around 2300.
I would pick a converter that is going to be the best for you when you start getting some mods. I would not get a converter for the gears you have now or the cam you have now. You will end up changing it later. A 4000 is going to be better performance wise than a 3200, regardless if you have stock gears stock cam or not.

The difference between a 3200 and a 4000 around town are minimal to non existent, like I have shown. The difference between them at WOT is great. Around town at a quick pick up (pulling away from other traffic pretty quickly) is around 2600-2700.. On a normal pick up (staying with the traffic beside me) I pick up around 2000-2200.

I would most definitely go with at MINIMUM a 3600... IMO a 4000 is a killer all around converter.You could always find a stock 6 speed rear with 342s and switch them in.. Or I have a set of 323s I would sell you for next to nothing if you want.

read this whole thread and just recently bought a vig 4000 mine is not a DD and is currently a bolt-on car w/ 3.73 gears with plans of h/c in the near future

Thanks a lot lemons, ya the hwy thing atm is why I'm trying to stay away from gears and by the time I add the 300 it'll cost for a gear install with bearing etc I'm in it for a lotta dough lol. I've got the tune handled so that wont be an issue, are the vids of your car with 3.23's in the rear? If so do you think the 2.73's to that will be a big difference rpm wise taking off? Sorry if I'm annoying you I just keep getting various answers from people and wanna do this right.

You will be happy!

Yea I hear ya man.. The car in the vids has 373s.

You could pick up a rear from a 323 car and install it yourself, it would be cheap and better for pick ups.. If it were me I would grab a 342 rear... The difference in MPG on HWY is probably going to be around 2-3 MPG. If that matters to you then don't do it but it will be much nicer around town. You could probably get the rear for around 150$ or so and install it yourself in a few hours or so.

Just a thought.

Heres 2 of the vids on youtube both members here and have replied in the thread. The ss i believe has 3.23's in it and a 3200 stall so it shouldnt be too much worse with the 2.73's but IDK the next is a 2.73 car with a ss4000. The 3200 car is fine not loose for me at all the 4000 is kinda iffy. This is where I'm stuck I know i'd be good with a 3200 but idk how i'd be from a roll and therefore am wondering if I should do a 3600...decisions decisions

From what I could tell 1900 RPM pick up for the 3200 and 2200 RPM pick up for the 4000.. For me, I could sacrifice for the difference under WOT. Remember, once you hit lock up it will drive like stock. And if you do mainly HWY driving it will be like having a stock converter in the car.

That was super light throttle going down my neighborhood street with the 3200. A lil more would be needed to move with traffic. And yes it had 3.23s. Going from that to a Yank SS4000 I can honestly say they are very similar. Average person couldnt tell. I notice a tad bit more rpm to get moving but not much at all. Couple hundred at best.

i can also say the swap from a 3200 to a 4000 is not noticeable until you hit the g pedal. then you'll be able to tell.

The girlfriend had a TCI 3200 in hers along with 373s (same as me)... It was a VERY tight 3200.. It was around 250-300 RPMs difference in picking up around town. The WOT was amazingly different.

Thanks for the help guys everyones just telling me I need to do it and I'll love it lol. This vid is of a pt4000 I couldnt find any info from yank but does anyone if its tighter or looser than an ss4000? And after looking at the vid I think a 3600 maybe best the shift extension of the 4k looks to be about 5400 rpm which is a little too much for a stockish car, I was thinking a 3600 would put it down around 5k. Also do any of you see a big difference in driving the car with a stall vs one having 3.23's or will it be minimal? Ive been looking at various stalls and am still trying to figure out, does a lower str rate mean its tighter down low and less up top or does the higher str feel tighter low?

Higher str equals tighter feeling. PT series is looser then SS series.

Very recently went from an Yank SS3600 to an SS4000. I can definitely feel a difference. The "lazy" effect of a loose converter when trying to get the car going from a stop or trying to accelerate moderately in traffic is more exaggerated with the SS4000. It also seems to hit a good bit harder from a roll and from a drag strip launch - which is the whole reason I "upgraded" - so it is doing what it is supposed to. Haven't been able to compare 60' times because the SS4000 is so new to me that I have only been to the track once with it - and blew off the tires every launch. I think once I get the shock settings dialed in for it and go back when they actually prep the track , I will be happy with the change.

That will not be too much for a stock car.

Higher STR means it hits harder out of the hole but is not as efficient on top.. Lower STR means it has less out of the hole but continues to pull hard up top.

Well, one of the reasons (there were others) that I went from a SS3600 to a SS4000 was that my engine speed was dropping 1400 RPM on upshifts. I was aiming for only a 900 RPM drop . I talked to Dave at Yank and he thought switching to a SS4000 would do it. So far, the data logging has confirmed an approx ~1K RPM drop on shifts, so it is basically accomplishing the mission in that respect.

There is also a good writeup/discussion about STR ratings on Yank's website.

That's my car. The PT series is typically a little looser than the SS. My car has a 2.2 STR with 3.23 gears. Shift extension on this converter would be perfectly suited for a higher shift point, but it does VERY well with an SI car. I've tuned two SI cars, one had an SS3600 and 3.23 gears and the other had an SS4000 with 3.90 gears. Both are very nice converters, and if my car already had an SS3600 in it I probably wouldn't go through the expense to replace it. However, after owning a Vig 3200 car and tuning both of those cars I bought a PT4000 if that tells you anything. My car dropped over a second in the 1/4 after the install, and ran the time in my sig. Full weight, daily driver, Nitto 555R II (road race) tires, stock internals, leaving the line SOFT so it would hook (1.65 60').

Definitely not too much for me! And again, this is my daily driver street/strip car. You are correct on the STR descriptions, but I also want to let everyone know that I am still trying to hook my PT4000 with 2.2 STR AND it pulls like a raped ape on the big end. I can't imagine trying to hook with a 4k stall and 2.5+ STR. I have replaced much of my suspension with UMI parts, but still need their torque arm and Strange shocks. Hopefully that will do it, but I still have my doubts about hooking even on a 315/35R17 DR.

These are the reasons I chose this converter for my application though. I knew I wanted a strong pull up top, I knew I'd always be running a drag radial, and hooking on the street is more important to me than the track.

lol "pulls like a raped ape"
my ss4k locks up about 45mph under light trottle. when it does and i slow down a little it makes a noise. like it really bogged down or something. get kinda annoying, to the point where i will down shift into 3rd gear or rev it up to make it downshift.

Is That Normal?????

iTrader: (11)

Mine did it too, but closer to 40 mph and below in OD. It can be tuned out pretty easily if you know someone with software, just have to set the table not to lock the converter below a certain mph.

lemons12

iTrader: (71)

If it locks at say 45mph it wont come out until 35-40mph.. Just don't go below that.
