Can someone explain a torque/stall converter for me?

[khc3]

What's it do, in simple, dummie language? Will a change improve throttle response?

TIA!

Check out this link (http://www.tciauto.com/tech_info/torque_converters_explained.ht m) from TCI Transmissions...it tells you WAY more than you've ever wanted to know about torque converters...

Converter Info from Yank Converter (http://www.converter.cc/technical_discussion.htm)

If you didn't feel like reading all that excellent info, here the quick version.

Think of two electric fans facing each other, one is on. One blows the other, the other turns. This is what a torque convertor does, but between your engine and transmission.

How hard they blow, how fast they accellerate, how much they weigh all affect how your car accellerates. It has nothing to do with throttle response, only accelleration.

Excellent, thanks!

It may *seem* to improve throttle response at WOT due to a harder launch (ie. getting your engine up into the power band sooner right off the launch), though.

And depending on the torque converter, it might actually soften the throttle response at lower throttle openings.

Once the torque converter clutch locks things up, though, there should be no difference in operation, only build quality.

many of us have installled in our marauders is the Stallion Torque converter made by Precision Industries. And they recommend a 3000 RPM stall speed which is about 500 RPM higher than the stock converter to my knowledge. But from what Precision Industries claims on their website, stall speed isn't the only factor that will dictate the performance of your car, and how it accelerates. The torque multiplication ratio is also a big factor too. And precision Industries is the only company that I've ever heard of who actually lists the actual torque multiplication ratio of stock converters as well as their converters. Go on their website and you'll see what I mean. It's www.converter.com and at the top of the page click on the "Stallion" link. They have two models of the Stallion. The single plate ($800) and the multi-disc ($1100). But they told me that the multi-disc model isn't really neccessary unless you'll be running on the track a lot.

And this thread, since people still ask about this stuff, thought I would revive it.

Will a aftermarket TC have a negative or positive impact on the gas mileage if maintaining traffic laws:)

On a standard car with manual transmission, you can rev it up a lot - then let the clutch out = This is like having a high stall converter.

If you were to take the same car and let the clutch out just off of idle - it will move out much more slowly if the engine doesn't die. = Low Stall Converter

Automatic cars like ours have the "clutch speed" or "stall" built in as there is no 3rd pedal.

I doubt anyone else explained it like that... ;)

Funny. I was just thinking of this stuff earlier today. Thanks for the thread revival.
