Do torque converters increase torque?
The main characteristic of a torque converter is its ability to increase torque when the output rotational speed is so low that it allows the fluid coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a reduction gear.
Is a bigger torque converter better?
“The more power you have, the harder the engine will try to drive the converter, and a smaller converter would be very inefficient in an application like that.” According to Reed, the stator will be locked up while the car is on the brake, and at some point in the run, depending on combination, it freewheels (unless it …
Does a Turbo 400 have a lock up torque converter?
To take advantage of these exciting new converters, Coan Engineering has released a kit for the TH400 transmission that allows you to use a lockup-style converter.
Should I upgrade my torque converter?
Switching to a higher stall-speed torque converter can provide the benefit of increased launch RPM and better low-speed acceleration. Once your vehicle is up and moving, though, a different converter will have little effect.
What are torque specs on a TH400 transmission?
The TH400 is an automatic shift, three-speed, longitudinally positioned transmission. It is widely regarded to be a supremely durable and legendary transmission. The TH400 is conservatively rated at 450 ft. lbs . of input torque. Aftermarket building techniques take it well past that figure.
How much does a TH400 transmission weight?
Some areas are cast iron, such as the center support for the transmission. The TH400 is 24.37″ long and comes in at a weight of 135 pounds dry. This transmission does vary in the amount of fluid required, based on certain specifications such as which torque converter is used.
What is Turbo 400 Trans?
Chevy’s Turbo Hydramatic 400 (TH400) transmission is one of those legendary pieces of equipment that helped to define the muscle-car generation, and it continues to be one of the most common and highly regarded transmissions in today’s enthusiast market.
