Is a stall converter the same as a torque converter?
A torque converter has three stages of operation: stall, acceleration, and coupling. Stall is when the transmission is in gear, but the brakes prevent the car from moving. As for stall speed, Greg Ducato, of Phoenix Transmission Products, explained that “a torque converter is like a clutch.
What is the advantage of a high stall torque converter?
A higher stall torque converter will let your car accelerate better because the car will be taking off at the rpm range where it is making the most power.
What is a good stall for a torque converter?
Stock torque converters generally have a stall speed around 1,800-2,000 rpm. Higher stall speeds become necessary when horsepower and torque happen at higher rpm ranges. You want stall speed and maximum engine torque to happen around the same rpm range.
Do you need high stall torque converter?
The rule of thumb is if the engine is coming alive at 3500 RPM then you want a converter with about 3500 stall to it. Many people will tend to over cam and carburet their cars, and those people under stall which sucks.
Does a torque converter add horsepower?
An automatic transmission in general has a way of soaking up horsepower, but the torque converter can take a potent combination and turn it into a pig when the rubber meets the road. And while stall speed is important for a good launch, it’s also a place for horsepower to swirl down the drain.
How do I increase the stall speed on my torque converter?
A large cubic-inch engine will raise a given converter’s stall speed. Engines that produce more low-end torque cause a given converter to stall at a higher rpm. A heavy car with large diameter tires will raise effective stall speed as installed in the vehicle.
What are the signs of a torque converter going out?
6 Signs of a Failing Torque Converter
- Loss of Acceleration.
- Slipping Between Gears.
- Vehicle Won’t Shift at All.
- Transmission is Overheating.
- Transmission Fluid Leak.
- Bad Transmission Fluid.
What should the stall speed be on a torque converter?
Most of the factory torque converters are 12-13 inch diameter and have a stall speed around 16- 1800 RPM. This promotes excellent fuel economy and drive ability because they are specifically designed for these purposes. The problems arise when the modifications are done to the fuel system, camshaft or other engine control systems.
What are the dimensions of a torque converter?
Performance torque converters are generally grouped by size (diameter) and stall speed. As the diameter of a torque converter decreases, the stall speed (RPM) goes up. Most of the factory torque converters are 12-13 inch diameter and have a stall speed around 16-
Can a high stall converter destroy a transmission?
Plus, the higher the stall speed, the more heat the converter will make with hydraulic fluid inside of the converter. Normally a high stall converter will be able to make enough heat to destroy a transmission if you are holding the line too long at full RPM if the stall speed is higher than 3500RPM.
What kind of torque converter do I need for a stock 350?
With a stock-type fuel pump and a Turbo 350 transmission, a good converter here would be a 2,000 to 2,200 stall converter.
