What is the difference between a comet 20 and 30 series?
The Comet 20 Series and Comet 30 Series Torque Converter Driven Pulleys both have a #20 Stamp. This Stamp does not determine the series type, ignore it completely. It's the degree of the angle of the component. Asymmetric Systems have all the working parts on the same side.
How much HP can a 30 Series torque converter handle?
Comet 30 Series Torque Converter System (Asymmetrical) Comet 30 series torque converter system is for 2 or 4 cycle engines up thru 8 hp. The model 30 uses a 3/4" top width asymmetric belt.
What is the difference between torque converters?
Unlike a regular fluid coupling, however, a torque converter multiplies torque when there is a difference between input and output speed, similar to a reduction gear. ... A torque converter has three stages of operation: stall, acceleration, and coupling.11-Jul-2008
How do I know what series torque converter I have?
Determine the exact series, measure the outer diameter of the driven pulley and measure the center distance. That's the only way to determine the correct belt.
Is a bigger torque converter better?
Larger-diameter converters are usually more efficient and deliver less slippage, while smaller-diameter converters offer more stall speed and more slippage. Vehicle weight is another major factor that should be considered when selecting a converter.14-Oct-2003
How do I choose the right torque converter?
Ideally you want the stall to lock up somewhere close to the peak torque of the engine. Typically engines that produce more low-end torque will increase the stall speed. The same converter will stall at a lower rpm behind a less torquey - higher rpm engine.11-Jun-2021
Which is better torque converter or CVT?
Torque converter transmissions offer big torque at low revs, but are generally less efficient than single and dual-clutch transmissions. ... CVTs offer nearly an infinite number of gear ratios, meaning your engine is always working at peak efficiency, regardless of speed.
What size belt does a 40 Series torque converter take?
40 series, length 33.87", width 7/8", used on many Manco karts and most Carter 40 series karts. 12346 Drive belt used on Manco model 710. 40 Series belt 7/8" wide. Used on Comet 40 / 44 series torque converters, these belts are all 7/8" wide.
How do you measure a 40 Series torque converter belt?
Simply take a measuring tape and hold it against the outer plate of the pulley. Measure from one side of the plate to the opposite side. If you're running a standard torque converter the diameter will either be 6-inches, 7-inches, 7.5-inches or 8.5-inches.
What size stall torque converter do I need?
For mild performance cars with something like a 350 HP engine, a 2,200 - 2,400 stall is about right. The basic rule of thumb is; if your engine "comes alive" at say, 3,500 RPM, then you want a stall converter with about 3,500 of stall to it.15-Dec-2020
What does a bigger torque converter do?
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.
Does a torque converter 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.
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.06-Dec-2016
What is the difference between a 40 and 30 series?
The 40 series has rollers and the spring holding all the rollers together, the 30 series has circular weights and circular springs.
How to tell the 30 series from the 40 series?
In terms of appearance, the way to tell them apart is from the angle in the leaves, the 30 series will be asymmetrical and the 40 series will be symmetrical, apart from that, the 40 series will be much more heavies and have a bigger belt.
What is the best spring weight system for a 30 series?
Likely if you’re to go with the 30 series, you have a smaller engine such as the predator 212, the best spring-weight system is the one that engages at an RPM at which your engine produces maximum torque.
Which is stronger, the 40 series or the 2.?
Since 40 series are built for higher rpm engines, their belts will require to transmit more power from the crankshaft to jackshaft, so they will be stronger of the 2.
What size crankshaft is in a 30 series?
The driver units of 30 series comes for both 3/4″ and 1″ crankshaft, and the 40 series comes for 7/8″ and 1″ crankshaft diameter.
Why do you make a spring stiffer?
Basically, you make a spring stiffer to get more power out of the engine at a particular “speed reduction ratio”. You can read more about the driven upgrade in this article.
Do torque converters face each other?
Or put in other words, the 2 movable parts of the torque converter will face each other (of course, the driven half will go into a jackshaft, don’t put both the movable parts in the crankshaft)
What is the torque converter?
Larger in diameter than the driver and frequently called the torque converter, its greater diameter multiples available torque, that results in a corresponding reduction in RPM of the vehicle's driving wheel (s) in relation to the RPM of the engine.
Is a comet fully automatic?
Weather-proof, completely mechanical and occupying minimum space, they can operate mounted in any position and are adaptable to a wide variety of applications, both stationary and vehicular. Each Comet system is fully automatic and can be used anywhere that control by engine throttle alone is desireable.
Is down shifting automatic?
Since ratio selection and "down-shifting" is automatic, braking and vehicle control are enhanced. Even engine and drive train component life (sprocket, chain, bearings, etc) is extended since shifting is smooth and not subject to the hazards of manual control.

Major Differences
- In terms of appearance, the way to tell them apart is from the angle in the leaves, the 30 series will be asymmetrical and the 40 series will be symmetrical, apart from that, the 40 series will be much more heavies and have a bigger belt. The differences in parts are stated below.
Performance
- Both the 40 and 30 series are made for different engines entirely, so it’s actually difficult to compare the performance since you can’t really use them on the same engine. But, what if you tried to compare them in the same engine? Can you use the 30 series in more powerful engines? It is not recommended to do, however, many people use a cheap 30 series on an Upgraded Predat…
Original vs Clone
- As you might already know, the original USA-made torque converters are going to cost you double the money, so are they really worth it? In my opinion, the clones work just as fine for most purposes, of course, the original is made of better and heavier materialsbut they are also 2-3 times the cost. If budget is not the issue for you then sure, you should go ahead and buy the orig…
Final Verdict
- Torque converters are amazing for off-road go-karts which require high torque. Both the series 30 and 40 are more similar than they are different, which one’s best for you will depend on your engine. If you have an engine with a max power of 2-8hp then go for 30 series and if your engine has max-power of 8-18hp then go for the 40 series. You can modify the springs and weights in t…
