Yank 3200?

So I have an L99, and I was recommended a LS3 Cam Conversion kit (w/ Cam, what size please advise) with a "Yank 3200". I have no idea what all this means (especially the Yank part), and I dont know where to begin a search even.

Im intersted in a Muscle car idle with sustained drivability also @ freeway speeds. I dont want those surging issues coming with big cams I hear about. Horsepower is a goal but not my primary.

yank is a brand of torque converters. the 3200 stands for the stall rpm that the torque converter begins to transfer power to the wheels. so when you stomp on the gas, the engine jumps to that rpm and you start hauling ass! the stock torque converter stall speed is only 17 or 1800, 3200 is probably the highest you can go without screwing with driveability on the street.

I have the Yank ss3200 in my l99 car and it's great on the street or strip. It will have to have more rpm to get moving on the street so you will burn more gas. But damn if it don't raise hell on the strip. I would recommend you get used to it before installing a cam.

Alot of times a converter is used to decrease the "surge" from an aggressive cam when driving the car( when you're at a light or stop, it'll want to lunge forward a bit with an agressive cam), it'll also provide you with the means to a much improved 60ft if you drag race it. I'd suggest with any converter that you go with a trans cooler as well...it's cheap insurance for these expensive transmissions.

I want a stall converter too...

I hope you have a nice chunk of change for all this cause you're gonna need it. The LS3 swap isn't cheap. What are your goals for this car? If you just want more power, there are a few good VVT cams out there for the L99. The Stall isn't necessary unless you have some big plans for it. Gears would be a better investment at the start.

Well they want 1450$ for the LS3 Conversion Cam Kit. Comes with everything for the swap.
They didnt price the yank 3200.
I plan on Supercharging . . . . I meam like a year down the road though AT least!

A converter is probably the best thing that you can do to an auto SS other than forced induction.
For ther street 3200 is probably the highest I would go. I just installed a 2800 PI converter in my car and it made a nice difference.
If you are going to install a cam you will want a higher stall converter. It will keep you in your powerband. With just about any cam you are going to lose some botton end torque. The converter will get you in your sweet spot of the cam coming on power.

Every Auto car shoould do a higher stall converter. This will close the gap with the 6 speed cars.

A trans cooler is a must on any converter swap.....and a good converter will lower your ET by .5-.8 seconds with no other mods, so it is one of the best bangs for the buck.

The FTI/RevXtreme Performance & Engineering is probably the absolute best you will ever find and is less than $800 for the billet unit. The 3600 drives like near stock on the highway and around town until you hit it, and then you right in the powerband instantly.

The FTI feels like a 3200 or less when driving normal and we have yet to break one in the years we have been using them. PM me if you want a quote.

Consider reading these two threads before you do an LS3 conversion.
http://www.camaro5.com/forums/showthread.php?t=80797
http://www.camaro5.com/forums/showthread.php?t=82272

The only bad part of the L99 is the DOD/AFM lifters. The VVT is good if you get the right cam spec'd out. It will help reduce surging and keep more power under the curve than an LS3 with the same cam. The stock L99 lifters is keeping the engine from revving higher therefore replacing them is a good idea.

Someone mentioned gears...IMO good option for an M6 but for the same price as a converter I'd get the converter, until gear prices drop to normal pricing.

Your converter should match your cam. There are two types of converters too. Yank is a single disk and there are multiple disk converters too. The single disks cannot be locked at WOT like the stock multidisk but there are sometimes tuning issues with the multidisk. I persoanlly will get a multidisk converter at a later date. This is a good start for converters:

You want to pick your stall speed based upon the appropriate RPM range of your power curve. A 3200 stall on a stock car is a little high for my taste. If you car makes power at higher RPM, you will want a higher stall speed than a cam that makes more low end torque.

Exactly, just because you have a cam doesn't mean you need a really high stall. I had too big of a stall on my old LT1 for the cam I had. I never got to use all the low end torque it made.

Stall (And a Cooler) and a Tune is a good start.. but I would skip the Cam on the L99 and just save a little more for the Maggie. For the LS3 a cam is a good idea.

Bumblebee put a great tranny cooler setup on his Camaro. Check out this thread: http://www.camaro5.com/forums/showthread.php?t=83473

Take a good look at Post #10. That shows what a good tranny cooler keeps you from experiencing.

The SST Camaro will have a converter in the 3200 - 3600 range. We will set it right at the base of the torque plateau.

Also, it goes without saying, make sure that any converter you get for your Camaro is a Lockup converter.

I'm interested in seeing more builds with looser stalls in these cars. Coming from an '02 with most bolt-ons and an SS 3800, I can say that even with the 3.23s, I thought I'd love to have gone to a PT4000 to PT4400. I NEVER thought that stall was too loose and that when the time came, I'd have had it upgraded. Most people driving street cars didn't go that high, and I can say that it was totally nice on the street with a good tune. I'm really interested to see if these cars with these trannys and gear ratios can benefit from these bigger stalls. I remember reading a GMHTP article where they used a Vig' 2800 (I believe) and I just didn't think it was as good a gain as I, personally, would've liked. My car lost a half-second with my stall and DRs, and my brother's, who's car was equipped almost exactly the same, dropped .7 in the 1320' and that wasn't even as good as it coulda' gone, IMO. Anyways - I'm looking forward to someone going with a bigger stall and seeing what gains, over the smaller (2800-3600) stalls. Regardless - make sure you listen to those that know how to match converters to your combination and what your expectations are Also - talk to the 'verter companies and get it straight from the horses' mouth

Bigger isn't always better, you really need to spec the converter to match your cars power. Stock L99 lifters can't rev as high as an LS3 so extending the rmp range like you did on an LS1 isn't so simple with an L99. If you have a cam that makes made power at 3000rpms you dont need a 3600 stall. If you delete AFM and add a big cam then you might need to look at the usefulness of a larger stall. This is based on what I've learned over the years, but I'm not the expert.

Looks like I will be getting a converter sooner than later (leaking rear main) Can I get a canned tune from the converter mfg or some one like Jannetty or is this a dyno only tune?I will be talking to the converter mfg.It will end up with cnc ported heads and a mast vvt cam these cams seem to make TQ way down low and the fact it is my wifes daily driver I am thinking a 2800 stall.Opinions are welcome.Thanks

You'll want to advise the converter company of your cam specs', rear ratio, and a bunch of other stuff for them to match you a good stall. Also, you might see if you can find another car with a stall to either go on a drive in, or at least just ride along with. The feeling of looseness is subjective, so my idea may be a lot more liberal than yours; and vise-versa. If she wants to rip it up, then a higher stall will probably be what you guys are looking for. Then, there come terms like Stall Torque Ratio (STR), Shift Extension, and some others that can come up too. The higher the STR, the lower the efficiency (most of the time), but it'll hit really hard off the line and probably help make up for the weight of the car. You might trade some power on the top end, but STR will make the car feel a lot more torquey. It should be easier and more livable daily. I know Yank used to go to 2.55 or 2.60 STR on their Super Stock Series (SS), and those RIPPED on the street. They had even higher efficiency than the OEM 'verter too. My traps actually increased over my OEM 'verter without any other mods'. I loved that SS and the Pro Torque converters really had my eye, like I said. The SS was about the most efficient for the street though, and I can attest that it sure was.

I'd make sure to consult your tuner regarding your expectations too. I know with the 4L60W, TM was really terrible, and would totally kill the power on the car. Deleting shift codes really made the car's drivability and track performance shine, too. Increasing line pressure, quickness and firmness and adjusting shift RPM AND MPH were also critical. I don't yet know how the 6L80E responds, but I can tell you tranny tuning can make or break a converter. If your tuner, regardless of canned or not, has a firm grasp of the 6L80W, I'm sure you'll be okay. Be aware, though, that a lot of these functions also are there to preserve the tranny, so if you play with those, it's possible that it'll be a lot easier to abuse that tranny and get that car in trouble quick. If your wallet can take it, have at it.

Good luck and keep us posted

I just ordered my converter from Yank. They suggested I get the SS2800 converter since I already have a Magnacharger installed and I wouldnt need much help to get a good launch due to the Magnacharger producing alot of low end torque. I have the L99 with the AFM tuned out. Yes I know. They dont have the SS2800 on the website yet! You can order your trans cooler from them too!
