TC Stall Speed
 

I have seen this mentioned a few times and since im not a hardcore track guy i never paid attention to the meaning...i know a few members have the HS TC..but what does it do and what are the benefits for the track guys.....not like ill ever need one :lol:

From what I understand, The higher the stall speed, the more the torque converter slips untill it actually puts power to the transmission. The advantage to this is when you take off or hit the gas, your engine is closer to it's powerband. Another advantage is you can power brake to a higher rpm so you can put more power down when you launch. Gears, and engine torque vary the actual stall speed.
A disadvantage to a higherstall is lower city fuel economy. Since the torque converter is slipping more, lower rpm power is lost, and your engine is reving higher before you start moving which means more air/fuel.
With all the aftermarket tq converters I've seen for our cars, they can still lock up, so highway mileage should be the same. I have seen people have issues with lock up on higher stalls though.
And I've also read that a higher stall lowers your overall hp output a little since it's slipping a little.
Hardcore guys correct me if I'm wrong but that's what I've gathered.
Edit- Forgot one more thing. All that slipping going on raises tranny temps too.

I've driven one with a higher stall, and didn't like it. And I don't think it benefited him at the track either.

You can def. tell the difference with a higher stall. It should help out an N/A quite a bit and I've heard that it will nock of a few tenths in your E.T.

There is more to converters http://www.converter.cc/tech.htm they have some good info

I have a 2800 RPM stall torque with 3.29 gears.......I love them ;)

Cheers,

Their are no disadvantages to having a high stall converter, exept comfortabilty. I wouldn't get one unless you plan on racing a lot. It will defanatly give you a better ET. off the line. It is harder on the tran for obvious reasons. If you have the money, go for all the upgrades you can get. Every little bit helps.

One of the big factors for having a high stall converter is a large camshaft. The bigger the cam ( more duration, lobe seperation, etc.), the more you move the powerband into the higher RPMs, and the less torque the motor produces at lower RPMs. Therefore, a higher stall speed will allow the motor to rev higher (and produce more power) before the tranny starts moving.

I ran my Camaro with the stock converter for a while, and takeoffs sucked. It seemed like there was no power until about 24-2600 RPMs. I could not spin the tires at all. I changed the stall speed to 2800, and had no problem peeling off some skins.

I just ordered and received a High stall converter from Intense. I felt that since Im having a new transmission put in on the 18th that I would buy a few goodies for it before it goes in. I hope to learn to use it to my advantage to help get my launches better ( bring my 60ft time down from 2.37).

I think you'll regret it for everyday drivability.
