What size stall should I get......

[clg82]

Just wanted to know what you guys suggest, for a stall size for me. I talked to my mech and he suggest this stall: PRO THRUSTER 4000 4L60E/4L65E LS1
245mm, Stall speed 4000 and 4400, Posi Lock-Up Clutch w/Kevlar Linings, lightweight billet cover, 2.2 STR , but I was thinking of just going with the SS3600 what do you guys suggest? I rarely drive the car except for weekends or maybe out of town on occasion, and want something that is still comfortable to drive......let me know what you guys suggest and what will work well with my modifications in my signature~Chris

Do you have h/c or plan to soon?

The one the mechanic suggested is high for just a stock motor for street use. I think you would be better off going with a 3600 or even a 3400 with your current mods.

I would call up yank/hughes/tci/etc... tell them your plans for your car and they will help you pick out the proper stall for your application.

I have not picked out a stall yet due to I haven't even decieded on the h/c setup I want.

[Y2KPewterSS]

3600 for sure if you have no plans to cam the car and want to maintain good street manners with the car. If you ever do plan to cam the car, pairing up the cam and stall are best for optimal performance.

Depends on your plans. I guess the way I look at a stall is more about STR. A stall with a 2.5 str will net you around a 1.7/1.8 60'. A 2.7 will get you a 1.5,1.4 and really pushing it 1.3 60'. If your talking track racing. Not street or roll racing its all in the 60'. Drop you 60 and watch your ET's drop. Your running 3.73's which would really like a 4000 stall. But it would really be better if you had a cam at least. Cam,headers,4000 stall and 3.73's here. 1.5 60's with a 1/4 mile time of 11.52 at 119/120 ish.

So even if i go with the 3600 stall i won't notice a difference? I barely ever go to the track and do mostly cruising around and an occasional ricer race........

With a higher STR, your low-end be stronger. You will lose a bit high up.

Don't forget tires, because you won't be able to hook. ;)

THE TRUTH ABOUT STALL TORQUE RATIO

STR has been talked and argued about for many years. The following information is what we at Precision Industries have found by doing our own testing to be helpful for you to try to understand this subject. Our competitors must have a crystal ball to figure the STR of their torque converters. There are a couple of companies in the performance torque converter business that do have the capability to test STR, MOST DO NOT! Precision Industries happens to be one that does have. Our test dyno has the capability to test from 200 ft. lbs. of torque up to 900 ft. lbs. of torque. The other companies use dynamometers that vary from 100 ft. lb. of torque to approximately 300 ft. lb. of torque. There is an old GM printed sheet that has floated around our industry for about 10 years showing the STR of stock GM torque converters that were built back then. Our competitors either use this sheet or are guessing because they have no way of knowing what the STR really is. They also advertise STR’s of 2.7, 2.9, 3.0, 3.2, etc. this is pure BS. All torque converter companies use the impellers, turbines and stators that come in the factory torque converters. In our tests we have never seen an STR over 2.55. Precision Industries do have torque converters with STR over 2.55 but these units have specially machined stators in them and are not worth the high cost for a street/strip application. If our competitors try to tell you differently just ask them to show you a picture of their test machine, not just a printout. The formula for STR is EXACT OUTPUT TORQUE ÷ EXACT INPUT TORQUE = STR. This requires a known power source and a data recovery system. STR is just what the name implies. The ratio of torque multiplication at stall. As soon as the turbine rotates (car moves) the ratio starts dropping rapidly until enough RPM has been reached for the ratio to drop to 1:1. The RPM that the ratio reaches 1:1 varies depending on other factors in and out of the torque converter such as impeller exit angle, stator design, impeller to turbine clearance, input torque (engine), etc. A fact that most everyone overlooks is that a torque converter does not make torque! It takes the torque the engine produces and multiplies it for a very short period of time. This is why some cars perform better than others with the same torque converter.

Some car enthusiasts put all kinds of money in the engine, transmission, torque converter, NOS, rear end gears, etc. then want to cripple the torque converter by lowering the STR to try and prevent wheel spin on take off. This is as foolish as pulling off one of the plug wires. Why don’t they finish the project and work on the rear suspension? Trying to tune your car by using STR is probably not very smart seeing how our competitors don’t have a clue about what STR their converters have, after all the stock torque converter you took out of your car has a STR of 1.9-1.94. The best way to get the right torque converter for your car is to buy it from a company that has a large database of previous sales for your kind of car. Then tell the sales person what mods you have made and what mods you intend to make and let that person help with the decision. The key words here are large database. The “Johnny come lately companies” have no large database or experience with what works with these late vehicles. Why try to reinvent the wheel with your hard earned money when there is bound to be someone in our database that has the same mods as you do and their torque converter/engine combination ROCKS! At Precision Industries we found out 10 years ago that STR is not the most important consideration when deciding on a torque converter it is the whole COMBINATION!

I love my 3800. Its a TCI, never had a problem with it. You will hear good and bad about every single convertor brand out there though.

The SS3600 is amazing and you won't be disappointed if you can't make up your mind.

Someone explained it already but STR is:

Higher (2.5) = better initial launch and probably tire spin
Lower (2.0-2.2) = better efficiency and mph in the 1/4 mile

I think for your use you'd want a lower STR to have a more efficient stall. Call Yank and they will NOT steer you wrong.

Thanks buddy that is what i planned on doing since I talked to you, i'm going to go with the SS3600 from yank.......~Chris

[allbaugh_04]

no problem...make sure you let me know what you think whenever it gets put in and tuned

[Johns00Z28]

The SS3600 is a great street stall but if you plan to go with a cam down the road you might want to go to a 3800 or 4000 now so you don't have to switch it out again.

[clg82]

So I will definatly need a tune with the ss3600 stall correct.........?

[MNR-0]

Max. effort (bias to track) stock LS1 = 4000
Performance stock LS1 (bias to street) = 3000

3600 without a doubt!

[mark21742]

Don't worry about it, I got bolt-ons and I wish I would of went with the SS4000 instead of the SS3600

As long as you have a good tuner, it's NOT an issue at all running a high stall.

[SINISTER-TA]

yank ss 3600...end of thread :yup:

I second that. I love mine. Yank all the way.

[02transamce]

what is the difference,performance wise,with a 3 disc torque converter vs. a regular single disc torque converter?is it worth the extra 200 dollars for a mild dd(slp lid,long tubes,off road y-pipe,magnaflow muffler,k&n filter and a pcm tune)

[allbaugh_04]

I'm pretty sure a multi-disk will be a bit stronger, I think you can make them lock going down the 1/4 mile as well. Supposedly that feels great and can gain a .1 or .2.

I'm really not sure though

[homerunhtr21]

I would also check out Circle D converters as thats what I have...Just stay away from fuddle by all means...Yank, Cricle D, Vig <---- any of those between a 3200-3800 would do just fine.

[346ci]

I'm another on for the Yank SS 3600, that's what I have on my bolt on car and love it

[JKB315]

We were talking converters at work today with a old school racer. When he heard 3600 stall, his eyes widened and he said there is no way you can run that in a almost stock, street car. I gave up arguing with him about how converters today are a LOT more efficient than the crap he ran back in the day.

[MNR-0]

You can run whatever stall you want. Ive run a 5500 in a 383 stroker and it was fine on the street. You just gotta get the right converter for the job.

In saying that, an otherwise stock car purely for street use, I would go a 3200 over a 3600 any day. If you are into track times then by all means step up to a 4000 and give the 3600 a miss.

I'd steer more towards the 3,600 instead of the 4,000 just because the 4,000 puts you so far up into the power band (unless you have a super big cam) it will hit so hard on launch you'll either have traction problems or be breaking parts if the tires bite......just my opinion

my mod list
1st exhaust/ cai
2nd valve springs
3rd 3.000 stall
I happily drove it like that for awhile before I did the heads/ cam

[derck_mullin]

Also, lots of new folks think you have to rev the motor to the stall speed to get the car moving, which is not the case. The car with a stall will act "normal" for the most part. It's more like you can dump the clutch at a certain RPM at any time under full throttle. So if your stall speed is 3500 imagine driving along in a stick...then mashing the gas and @ 3500 RPM you pop the clutch. The cool thing is prior to that everything is normal...you just gotta add a tranny cooler.

[Y2KPewterSS]

If I remember correctly, I believe the stock convertor is 1800.

[MoNsTeR_LS1]

i put a TCI 3k stall on my bolt on car and mann did it turn into a different car..traction is deffinitly a problem now, my car was sick the way it would hook before the stall on the same 275 nitto extreme drag or my 275 mickeys that it sits on now..def. going to have to do some suspension work like lca's and panhard bar..maybe softer shocks and springs. I'd soon rather have not put the stall in and ran on my stock one again..ah hell ill just put slicks on it :)

[TOMASINO]

thing is my converter wont lock up anymore so is time 2 change it, i ordered super stock 3200 from yank for my stock t/a i hope it works fine for street driving

rebuild the tranny?? mechanic said transmission is fine just the converter got messed up (clutches) all i need to do is replace the converter but since im not puttin a stock back in, better 2 put a performance one rite???? since im not good at this, mechanic recommended this stall for my stock car

You can go bigger if you wish, just needs a tune to get everything you want to get out of it.

it just seems like when you get into it on the street 3600rpm's is alot to flash to . i kow it will be better on the track.

The flash is almost instant. Don't worry about that. If you get a 3600 and a tune, you will be fine...trust me. I am going from a 3600 to a 4000 (new stall)

[mark21742]

[allbaugh_04]

I only have long tubes, 3" ORY, exhaust, ls6 intake and i had the 3600. I was happy, then even happier after I got it tuned for the stall.

I remember a post a few years ago about this that was about a mile long and went on for months. I listened to the guys who said to go big and I regretted it. I went with a TCI 3800 and I really got tired of driving my automatic like it was a stick. Rolling backwards at stoplights, double footing it from a start if going uphill. I ended up getting a custom one built after my tranny died on me. I went 3200. Your mechanic is just talking about something he has never experienced. Go a little lower and you will still be happy. I will tell you this, a stall upgrade does amazing things in the 1/4. Have fun.

[m1a2d3]

is having to double foot it at a stop light common with a high stall ? i dont want to have to deal with that.

They do have lock up clutches, I am pretty sure the PCM will only command lock up in OD, but don't quote me on that. If I remember right, my SS3600 locked up around 38 or 40mph in OD with the stock PCM tuning. Now it locks at 55mph...tuned through HPTuners
