A quality 3200-3500 stall speed converter, especially since you race.

2800-3000 hardly worth the labor of swapping.

Circle D FTW!

[Nightcrawler]

I have a Circle D 3500 stall. It's badass for driving around, but without being unstreetable.

[Mr. Man]

As I'm not an expert on this subject why would a higher stall speed converter be beneficial on a car that isn't used for racing, if it even is?

It is a personal preference.
What the high stall does for street driving, is to let the engine rpm slip higher from idle, smoothing the transition from dead stop through the gears at part throttle.
They also get the rpm into the engines peak torque area in a blink, rather than lugging there with a stock 'tight' converter.
You really don't notice the change as a 'racing' mod, until you drive as if you were racing = full throttle hit from idle. Or while rolling at any rpm under the stall speed.
rolling at say 2000 rpm, mash the gas, the car does not bog, and climb it's way up the rpm until shifting.
It flashes right to the stall speed, rips the tires, and since the rpm are now in the torque range, the car moves quickly to the shift rpm point.
There when you want it, tame when you don't.
Most have no adverse on fuel consumption, might actually improve, mine did.
I put a stall converter in everything I drive, except the new Honda.:P

I have a Circle D behind my LY6 in my GM product. 3200 stall and it drives nice in town. It will pull the car on flat ground right off idle if you drive nice. I would love to put on in my Rauder too. The support staff was great too.

[chief455]

Added note to the OP:
while 'you get what you pay for' is very true in my converter experience, at my current 400rwhp level, I've got around 7000 trouble free, consistent performance miles on my 10" 3500 stall from Roadrunner Converters. Never shudders or slips on lock up, never over 195* trans temp on stock trans cooler only. I would swear it cost 900 bucks.
$345 -:eek:

If you plan on more power, I'd go the Circle D/Preciscion / Yank / Neil Chance etc known quality brands.

Have a 3500 from Precision Industries for over 10 years and I love it!

Interesting information :up:

- I've always been lead to believe that high-stall torque converters were track gear that gave you better launches but had a lot of driveability issues otherwise.

hog wash. Only if they installed a poor converter, or dramatically wrong for the application (5000 rpm stall converter in a cold air intake only car)
Perhaps tuning the trans shift schedule is more challenging with a high stall converter, but anyone worth anything doing tuning, has stall converter experience.
I'm think some guys have just put stall conerters in and burned rubber!

non computer controlled transmissions = stall converter = instant fun :banana:

I had that Roadrunner. It's a 2800-3200 converter. It fried out quick, but I had other issues with my trans as well, so ????. Now I run one that's custom built for my transmission by a converter specialty shop in Rockford. It's perfect. 3500 is a bit much per most people's opinion I've seen on here for everyday driving. The 32V cammer's sweet spot hits at 3000 rpm, so why would you want a 3500? Really, if there is a tech reason why you would want that, I would like to be educated on the subject.

I have run 3500 stall behind mostly stock small cube (higher rpm) chevy and ford engines for years, loving every smooth city drive and long smokey burnout. I'm not alone ;)

[Mr. Man]

So in a nutshell, around town pooping along no super advantage but getting on the gas it will make a stock car fast, faster. Or did I miss the target completely?

Actually, my Roadrunner is rated at 3500, they sell them.
I don't want to write information I can't support with more than my own experience.
The converter stall rating, unless custom built based on your engine/gear/weight specs, is a ballpark figure.
Most manufacturers give a higher stall rating than 90% of buyers will realize, to prevent the guys from buying a converter too loose.
In my experience, a 2400-2800 rated, off the shelf converter, feels like stock.
2800-3200 feels like you are low on trans fluid about 2 quarts - it slips a little.
3200-3500 feels just right - BUT guys without experience of driving high stall cars jump in and say - "whoa - you got a real loose converter!"
After you drive the car in different traffic and throttle conditions, you decide if it it or isn't 'too loose' for your liking.
Keep in mind, they are designed to couple up based on the crankshaft torque.
So a 3500 rpm rated converter behind a crank that produces 250-300 lb/tq at 2500-3000 rpm, will probably actually feel pretty good on the street, and couple up between 2600-2800 (most buyers fall into this area).
That same 3500 converter behind a crank that produces 480 lb/tq at 4400 rpm, will be much closer to the advertised 3500, and likely flash to above 4000 rpm during normal driving. For sure will flash to the torque of 4400 rpm from a dead idle or low rpm roll.
This combination will probably feel too loose for most street guys, and might be mis matched for optimum track results.

"The 32V cammer's sweet spot hits at 3000 rpm, so why would you want a 3500?"
guys that like their 3500 rated converter behind an engine that has it's sweet spot at 3000, might like the feel of the extra couple hundred rpm slip higher into the torque range, and the converter might be getting less torque than designed for from the crank, so it couples up at close to that 3000 sweet spot. Some guys like a 2400-2800 converter, so more than one stall speed might be acceptable, thus comes to owner preference.

It has a specific science to it, so custom built to your specs is best.
But, off the shelf rated converters can do the job.
Hope this helps, and it is only my humble opinion and limited experience.

that's how I feel, yes. around town pooping, it will take away hard hitting, low rpm shifts, and soften them up due to being 'loose''. Sort of slide through gear changes. not racey, I think it actually makes the car less 'race' at low rpm, part throttle.
Get on the gas, from idle or low rpm roll, it will hit the tires in a blink at a higher rpm, either fry the tires, or pull like a freight train and hit the next gear not hard, as to rattle the dash, but shift quickly / repeat.
My brother has never driven any of my cars more than a few miles, until last weekend he drove it for a few hours.
He now wants a stall converter in his stock Grand Marquis and his 95 Chevy truck.
It's addictive. :cool:

OP - I suggest you call and talk to the guys at Precision Industries. They will recommend a convertor based on what you want for driveability and performance.

+1 - best suggestion.
while I feel my rough explanation to be accurate, the best source of your converter needs is the manufacturer.
I'd do some comp shopping though, talk to two or three converter tech guys.
You'll get a good feel based on what information they provide, and should you buy one they suggest, if you do not like it, they will typically offer to re stall it once for free.

Correct. Still have my PI re-stall if I need it.

[Loco1234]

I have run a 3200 stall PI for over 10+ yrs.... with between 500-800HP depending when it was dyno yuned over last 10+yrs...

Stall runs great still not 1 problem... knock on wood...

[JBeezy]

Interesting read in an old thread. I'm on the fence on which stall speed I want. I don't drive my car daily, but love driving it on nice weekends.

This is the same TC I'm putting in mine, with the triple disc

Assuming you have a tuner who can actually "tune" go with 3,500 as the min.

I have had a 3,500 for over 150k.

Centri blowers generally are better for higher stall converters, Roots, twin screw not as high needed unless personal preference

[Pat]

what he said ^^^^^^^^

My 3500 converter with Centri S/C kit, 4:10 gears and Mo's tune has been flawless and loads fun. Get up and go out the wazoo.

[JBeezy]

3500 it is

This is the way in understood it as well. Always thought that there was too much slippage for a daily driver. Always thought this changed your cruising RPMs like a gear change would.

Sounds interesting. I just drove 250 miles each way to a wedding this weekend and got 25 mpg cruising on the interstate @ 70mph. Car is stock except for K&N CAI. It is on 235/50s all around, so the speedo's a bit off. If I could keep my MPG for my highway trips (95 miles to the VA) and gain a bit when I step on it, that's a win-win.

What is a stock converter stall speed?

What is a stock converter stall speed?

^Stock and below 2000
notice how your car wakes up when above 3300 rpm, in any gear?
Stall keeps you in that sweet spot, unless you let off throttle. then it feels stock.
you guys are missing out on the fun!

[stevengerard]

3500 and 4.10s but I have a centri. 80k miles on it. Makes around town driving "fun"

[tbone]

A while back 3000 was the preferred stall. And an Aeromotive 340 was the pump of choice. Times change.....

No I'm not. [emoji4]
