Following this Forum since signing on to MM.Net, I hate to be so dumb as to humbly ask:

What is 'stall speed'...and what does a 'converter' do??

In the OEM Marauder, what is the difference between it and installing a different 'converter' if that is the right way to say it??

These questions arise from topics relating to the 'Stallion' and PI converters.
I'm NOT a wrench, but I can read OK!!

Please explain...thank you.

What you are takling about here is a torque converter. It sits between the output shaft of the engine and the input shaft of the transmission.

Think of a TC as two fans facing each other. The engine drives one side of the fan, and the other side turn and drives the transmission, which drives the rear end, which drives the wheels. Now, the transmission fan won't turn at the same rate nor with the same power as the engine side, it's not 100% efficient. As well, if you didn't have this set up, when you were idleing with the brake on, the engine would stall. (If you stop the tranny side fan, the engine side still turns)

Stall speed is where the transmission decides where to shift to the next gear. 'Lock up' is where a little clutch locks the two fans together, giving more horsepower and better efficency.

Just a slight correction: stall speed is the maximum speed that the input side of the converter can spin while the output side is stationary. You can test this by firmly holding the brakes and applying gas until the RPMs stop climbing (2500-2700 on a stock Marauder, I believe). If the brakes aren't firmly held, the rear wheels will start spinning in place. ;)

I'll go try your theory on a flashed set up this afternoon, report back the rpm number. :bounce:

Ooops, brakes weren't fully applied, stripes in parking lot now. :rock:

Those were 4 good answers:) Either TTA or Petrograde turned me towards the "How Things Work" website, and that was helpful in seeing what the torque converter looks like. I don't know what the RPM is on my car, but the wheels start spinning when the pedal is about 3/4's of the way down. I have this on video tape...and what a tape this is:baaa: :rock:

Dr Caleb:
Thank you for the info.
I need to spend more time searching this data base before asking a redundant question.

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... ;)

Wow, another Marauder in the Ozarks...let me get a hold of him for a chat....DOH!

Weekly entry for the award for the.............. "Oldest Thread Resurrected".

Must admit though, some great info on Torque Converters..:beer:
