What does a 2500 stall converter do?

A 2,500 stall speed doesn't mean you need to rev the motor to 2,500 rpm for the vehicle to move." What it does mean in this case is 2,500 rpm is the limit at which the converter will hold back the engine speed if transmission output is prohibited.

How does a 2500 stall converter work?

With that, if you take a car with a 2,500 RPM stall converter and you hold your foot on the brake hard, and hit the gas at the same time, (as if you were going to power brake), the "general" RPM in which the tires will break loose is at "about" 2,500 RPM.

How does a stall converter affect daily driving?

However, a stall converter will affect your daily driving by lowering your fuel economy substantially. This makes it a poor option if you're using the car for commuting. The reason that a stall converter boosts your acceleration is that it doesn't allow the tires to break loose until you reach a higher RPM.

Does a stall converter increase horsepower?

A higher stall speed torque converter DOES NOT add any horsepower. What it does, is move the engine rpms up higher at launch, so that you have more horsepower per mile per hour. Just like when you rev a stick shift car up higher for a quicker launch.

Do you need a stall converter with a cam?

If you build a 500-horsepower engine with a radical cam, then you will need a higher stall converter to allow the vehicle to idle.

Is a 3000 stall Streetable?

Is a 3000 stall Streetable? Most of the “daily driven” street cars we build have anything from 2,400 on up to a 3,500 stall converters in them and they are very streetable with no problems. Just because a stall converter may have a 3,000 RPM rated stall does NOT mean the car won't move until it revs to 3,000 RPM.

Is a 4000 stall Streetable?

With the majority of street cars that are driven daily we build have stall converters ranging from 2,400 to 3,500, with no problem being street driven. Whereas, we will sometimes use 4,000 RPM stall converters on strip / street cars.

What stall speed do I need?

When choosing the stall speed that is right for your application, a rule of thumb is that the advertised stall speed will need to be at least 500 rpm higher than the beginning of the camshaft's powerband. All aftermarket camshafts are delivered with a recommended RPM operating range.

Why do I need a stall 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. But you don't want a stall speed that is too high either.

Is a 3500 stall Streetable?

One of the biggest bangs for the buck you can buy is a stall converter. Most of the "daily driven" street cars we build have anything from 2,400 on up to a 3,500 stall converters in them and they are very streetable with no problems.

What happens if stall speed is too high?

Converter stall speed must be high enough to put the engine into the torque range where it can most efficiently launch the car. If converter stall speed is too low, the car will be lazy leaving the line; if too high, there'll be excessive high-gear slippage—either case adds time to your e.t.

Does torque converter affect acceleration?

By redirecting fluid flow, the converter multiplies the torque produced by the engine enough to propel a vehicle down the road. Most converters multiply torque by a ratio of at least 2:1, improving vehicle acceleration substantially.

What stall converter do I need for towing?

If your motor generates more power in the lower RPM range, you'll want to select a converter that stalls at the beginning of that RPM range. If you use your vehicle for towing, make sure your torque is around 1800 RPMs.

How do I know if my torque converter is stalling?

“Flash stall” is when you, from a dead stop, press the gas pedal to wide open throttle (wot). Watch your tach needle, you will see the needle jump to a certain rpm, that is “flash stall”. A drag racing-style trans brake will give you closer to the true stall speed of a torque converter.

What does a low stall converter do?

With a responsive turbo (especially the newer VGT models), a low-stall converter will deliver more power to the rear wheels and create less heat without lockup.

What is the stall speed of a stock 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.

What is a 2400 stall converter?

It allows the engine to launch the car at a higher RPM, where more torque and power are available. This can be especially important if other modifications (like larger cams) have reduced your low end power and torque. The Holeshot 2400 has a stall speed of 2300-2500 RPM (based on an engine producing 230 lb.

How does a high stall converter work?

Stall means when the car is on the starting line, (with say a 4,500 RPM stall converter), and the trans brake is on, (which locks the transmission in first and reverse at the same time), and you hit full throttle, the engine will wind-up to 4,500 RPM with the car just sitting there, so when you slip your finger off the ...

What is the stall on a stock th350?

A stock converter has approximately a 1,700 stall, +/-. If you have a 3.08 rear end, you would benefit from a higher stall converter if you are changing cams, something like a Hughes GM 25 rated 2,200-2,500 as an example so you can get that thing moving.

How do you calculate a stall converter?

What this allows us to do is determine what the stall speed of a given converter will be if we put it behind a different engine. For example, if a motor has 400 ft-lbs. of torque and stalls a particular converter at 3,000rpm, K = 3,000/sqrt{400} = 150.

What is the stock stall on a 4L80E?

GM 4L80E Night Stalker Series. Stall Range: 200 RPM Over Stock.

What is a 3500 stall converter?

If the converter was a 3,500 RPM stall, then it would be at approximately 3,500 RPM in which it forces the tires to break loose.

Does a stall converter affect idle?

With a high stall convertor it will probably idle even high because there will be less of a load on the engine, more like it idles in neutral.
