Re: Stall Converter
OK, here is my shot at it.
A converter works like two fans facing each other, one has power(engine side) the other one is driven from the first one(trans side) through fluid power, in this case air.
When both fans are turning at the same speed, this is what the other guys referred to as fully engaged.
You can change the stall speed by changing the number, the pitch,and the size of the fan blades.
A torque converter also has a stator, this redirects the fluid back through the driven side when the converter is stalling to double the torque output.
Stall speed is determined by two things, torque applied, and load against it.
A converter behind a 4 cylinder engine may stall 2000 rpm, put that same converter behind a 454 and it now stalls like 5 or 6 thousand. And that is how high stall converters are made. My 5000 stall converter for my big block is a modified quad-4 (I think that is what they call them little 4 banger engines) converter. They reinforce the fins, change the hub to fit a turbo trans,weld in balloon plates,and weld on reinforced drive lugs to fit V-8 flex plate.
The idea is not to get a high or low stall converter, but to get one that matches your combination. And alot of stuff comes into play, cam profile, tire size, gear ratio, truck weight,carb size,and more. My suggestion to anyone wishing to buy a converter, is to talk to a good company for there recommendation. They have computer programs and lots of experience to get you the correct one.Be prepared to answer a bunch of questions like above. If they don't ask them, then call someone else.
Did anyone really read all that? And I don't even type.
