How does gear ratio affect torque converter?
The less resistance against moving the vehicle, the lower the stall will be in the torque converter.” Now we’ll factor in gear ratio. “As the ratio gets larger, the engine has to turn more rpm to make the axle rotate the same number of revolutions,” Gill said.
How do I choose a stall for a torque converter?
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.
What’s the difference between 30 and 40 Series torque converter?
The 30 series is rated for 2-8hp Engines and the 40 series is for 8-18hp engines. So if you’re using an unmodified predator 212 or other honda clones with a max power of 6.5hp or lower, then 30 series is for you, if you’re using a more powerful engine such as the Predator 420 then go for the 40 series.
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.
Do you need high stall torque converter?
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.
What does a 3500 stall converter do?
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.
What happens if torque converter stall is too low?
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. Engine builders use car weight and dyno data to aid selection. The converter is also matched to the transmission’s gear ratios.
How much HP can a 40 Series torque converter handle?
8 to 18 hp
Comet 40/44 series is a mid range torque converter system for 8 to 18 hp applications.
What’s the difference between a 20 series and a 30 Series torque converter?
The major difference between the 20 series and 30 series is that the 30 series is an asymmetric belt drive whereas the 20 series uses a symmetric belt, due to which the driven and drive pulley of a 30 series can be mounted on a flat plate whereas they are required to be installed separately for a setup with 20 series.
What happens if stall converter is too small?
What happens if your stall converter is too high?
What is considered a high stall torque converter?
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.
How much HP can a 30 Series torque converter handle?
8 hp
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. Drive clutches are available for both 3/4″ and 1″ bore (with 3/16-1/4 keyway).
Is a torque converter better than a centrifugal clutch?
The Centrifugal clutch is ideal for high-speed Go-karts with small wheels on flat tracks. Or to put it more technically, Torque converters are useful when you require more torque (for example: driving uphill) and will give a better take-off.
What is a good street stall converter?
Can you daily drive with a stall converter?
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.
Whats faster torque converter or clutch?
They perform better at lower speeds and are ideal for stop-and-go situations. This is because off-road go-karts are sometimes required to climb uneven terrain at lower speeds. Clutches on the other hand are snappier and perform better at high speeds.
What is faster torque converter or clutch?
Mini Bikes with Torque Converters are faster than Mini-Bikes with Clutches.
Can you daily drive a high stall converter?
Can You Daily Drive High Stall Torque Converter? – YouTube
What is better centrifugal clutch or torque converter?
How much horsepower can a centrifugal clutch handle?
NORAM centrifugal clutches are designed to fit engines ranging from fractional horsepower up through 50 HP applications.
