i have a stock ls1 transmission, and so far i have intake,exhuast,programmer, im looking for another upgrade, i was looking for a set of headers, but i was just wondering if it would benefit me more to go with a stall since i have an automatic? and if so, which stall should i go with? im not looking for a low 12 or 11 sec car, just looking to hit maybe mid 12's/ high 12's thanx... i was thinking about a 2200 stall? or is that too weak? need your opinion guys!

Go with the Vigalante 3200 stall. Took 5 tenths off of my car.
Best thing you could do for your automatic.

Well, mine isn't installed yet, but what I did was go out and drive an example, and ride in another example, to get a feel for what I wanted to do. i took a ride in a Z28 with a TCI3500, 3.23 gears, and didn't like that at all. Way too loose for my taste. I drove a 2001 C5 with 3.42 gears and a Protorque 2400. it drove beautifully, I've got to say. Like stock, until you got into it. Power on the car was similar to mine (heads, cam, Blackwing, intake, longtubes, GHLs, dynotune, etc.). So, what did I end up with? I just ordered a Yank SS3200, and kept my 3.15 gears on my C5. This is more converter than I originally thought I would end up with. Why? I tried for a long time to hook up with someone for a ride in an SS3200-equipped car. No luck. I talked to a lot of people on LS1Tech and the Corvette Forum, Yank themselves and several vendors. This is what I was told by everyone. The Yank SS is a converter series designed to be tight, which is what I really wanted. My car is loud and I didn't want to have to rev up to get going from a stop everywhere. It's used as a daily driver, in nice weather anyway, and as drivability is very important to me, is how I chose my cam, heads, etc. The SS3200 was specifically designed for 3.15 gears (according to the Yank website). In all my research, I did not run across even one negative from a Yank SS series owner. That includes the SS3600, SS4000, etc. I decided to take the plunge and ordered one last week from Motorsports Technology. Great group price, which included shipping. i will probably have it installed in the Spring, but perhaps this Winter. What the little higher stall will give you is some boost in higher speed downshifting, also, whereas the lower stalls only help on takeoff (my understanding, anyway). If this SS3200 is as tight as I was told, I get the best of both worlds. Sorry I couldn't give you any driving experience yet. Good luck to you, and to myself!

what ever you do get atleast a 3,000 stall. Anything under that is pointless. With a 3k stall you should be able to drop .4-.5 in the 1/4 mile. A 3,500-4,000 stall would see .5-.7 or more reduction in the 1/4.. A word of caution is that the higher you go in stall the less streetable it is(depending on how you feal about the converter raising the rpms you need to just move the car). I had a 3,000 stall midwest converter that was great for street driving. I upgraded to a 3,800 stall and its way looser than the 3k. I havent driven my car much with the 3,800 so i dont know how im going to like the looseness a week from now.. At first with any converter change you will notice you need to press the pedal down more to move the same speed as the stock converter. Higer stall takes more pedal etc.. If you can find someone in your area that has a 3k,3.5k and a 4k stall and drive it to see how you like it.. I have my midwest converter up for sale 300.00 shipped but one other person is inline to buy it. If he doesnt ill send you a pm if your intrested.

Minimum 2800 stall ,if your looking for more 'KICK' try going to higher STR.
A 2.5 will roast street tires. You need to check into stall speed and what str you can handle. Simple note -the STR is the amount of torque from motor to trans before
lock up

i would also say a vig 3200, it stall a little higher than 3200 but is very nice. i drive my car about 15-20k a year and i love my 3200 vig. after about a week you dont even know it is there, until you get on it.

I would add this, if you go with a stall over 3000 get a trans cooler. They are cheap and easy to install. I have a vig 3200 as well and it is very well behaved on the street. You will lose a bit of fuel economy, however.

STR is the measure of the ratio of input torque to output torque at the rated stall speed at the instant the output shaft starts to move. Once the output shaft starts rotating the torque multiplication starts to decrease. Most of the multiplication is gone by the time the converter gets to it stall speed, but torque multiplication lasts to just about where the shift extension is.
Lock-up is controlled by the PCM.

he might be talking about fluid lock up(stall speed) and not the actual lock up of the clutch in the converter

Yank 3200 SS Great daily driver converter great response off the line in combo with headers and some good tires Nittos.

i think the common part of all post is the 3200stall part, which company depends on your cash flow.

Do you plan on getting a cam in the near future? If so, I would say get a 3500 converter or so, even higher if you will be getting a real agressive cam. I have a G5X4 and a 3800 TCi is too low of a stall for it. I will be trying out a Fuddle 4500 in a couple of months.

Waht's some of the prices that you guys are paying if yah'll don't mind sharing?!?!?

Yup, another vote for Yank SS3200 or the SS3600. My SS3800 is fairly loose around town, but once you get up to speed, say 30mph it will only spin 1500 rpm and once it's locked up around 40 mph it will drive like stock.

Out of curiosity, what are your gears?

i wouldn't suggest much of anything over a 3,500 if you don't want to lose some driveability. my fuddle 4k is loose loose loose. just for me to take off with traffic i have to spin right at 3k and carry it until lockup. i followed a semi and 53' trailer off of a stop light last night for kicks and at 2k it would hold even with the truck. however, stomping the gas pedal from any rpm under 40mph would immediately send the tires up in smoke (as i have radials on it now). my shifts only drop back to ~4,900 from 6k. awesome, i love this converter, perfect for what i want. 4k stall speed

edit: i have 373 gears.

I agree with going with a min of 3k stall speed. I had a TCI SSF3500 in my previous car. I loved it! If I had kept it instead of going to a m6 car, I would have wound up going bigger.

My advice...3500+. I liked my 3500 even before I had a cam, so it's not too big for just bolt ons. Good luck!
