Can some exlpain Torque Convertors?
I know what it is and how it works, but when I see when you have different stall speeds and such, that is what I don't know. What type of torque convertor would you add to a car with a 3.23 rear and will not see much track action. I would like something that is very good for highway spurts. This is for a 99 Camaro SS. Also thinking about adding a 3.73 rear will the new torque convertor. just need to know what to get to keep up with 6-speeds on the highway. thanks.

I went to their site, but they don't have much information. There FAQ section has nothing that answers any questions. Was there a specific spot on their site you wanted me to see? Thanks.

A torque convertor is the fluid coupler between the motor and transmission.
With a series a vains and gears that create torque mulitplication.

You're interested in stall speed of the TC. That's the maximum engine RPM before the TC can no longer spin with the brakes locked and so it "locks up" and the engine stalls.
A hi-stall TC, say 2,400-3,000rpm allows your engine to rev quickly to that rpm from a standing start. The purpose is to get the engine into it's power band for a quick launch.
Once you are moving and going through the gears, the TC lockup point has no effect on performance.
I have a 2,400rpm stall TC in my IROC 3.54 gears and when I launch the tach immediately jumps to that RPM. The Vette has a stock TC with 2.59 gears and the tach only jumps to about 1,600rpm so it launches a little slower than the IROC.
Choosing the best stall speed depends on your engine and the rest of the drive train. For highway spurts stick with the stock TC and increase engine HP for better performance.

So if you have a 3200 stall, and you hold the brakes and press the gas and it gets to 3200RPMs, the engine would stall and die? Or would the brakes give out and the car lunge forward? Sorry for the questions, just trying to learn something new. Thanks.
