How do I choose a torque converter performance?

How many of you drive a hot rod with an automatic transmission?

Automatic-equipped machines are the most prevalent, and whether you love them or detest them, choosing a torque converter performance is a decision that is guaranteed to be confusing. If you choose the improper converter, your vehicle will perform poorly at best and won't be safe to drive at worst. Here's how to choose the best converter for your vehicle.





Stall Speed

A greater stall speed allows the automobile to depart at a higher rpm in high-performance applications. Better performance, shorter elapsed times, and faster speeds result from this. This flash speed is frequently 500–2,500 rpm faster than the foot brake stall speed in many situations. You may alter the flash stall by altering the load that the converter detects. The flash speed might rise to 3,000 rpm in a vehicle with a 4.10:1 rear axle ratio and a 3.90:1 gear. Some manufacturers use the "foot brake" technique to promote the stall speed of their converters.


Converter Size

More torque (and horsepower) may be absorbed by a torque converter performance the bigger it is. Generally speaking, a larger converter will have a lower stall speed than one with a smaller diameter. The stall speed is directly influenced by a variety of factors that are external to the converter. Consult the relevant converter makers if you want to customise the converter for your particular combination.


Curves Of Engine Torque And Converters

Optimism may be harmful when choosing a converter, particularly when it comes to engine power. A performance converter with a tiny diameter will almost always slip more than an OEM converter with a wide, tight diameter. Under specific circumstances, installing a high stall speed converter causes an increase in engine rpm.


Choosing the right converter

Over 7,000 possible vehicle combinations have been digitized by ATI, which produces hundreds of various 8-inch conversion combinations. You can seldom ever expect to purchase a converter "off-the-shelf" and have it work properly for your vehicle. Consulting professionals is the only way to customise the converter to your combination.


Due to the varying nature of the requirements, the majority of aftermarket manufacturers want the following details:



Chassis

Vehicle weight is crucial since it informs the converter maker of the amount of effort required to achieve a specific elapsed time. It impacts gear ratio and helps to show what converter flash RPMs may be employed in a car's gearbox while still being useful. The manufacturer will compute the horsepower/gear ratio and the body type initially.


Performance

Between converters used for bracket or class racing and those used for street and strip usage, there are significant variances. The company is interested in knowing the current performance potential of your combo. How effective is the converter you use? They can make an educated guess as to how fast a new automobile you're creating will go.


Gear Ratio

What kind of tractor (and its gear ratios), the size of the tyres, and the rear gear ratio? To determine the exact output gear ratios is necessary. If the converter is working effectively when passing through the traps, you may know by looking at the trap speed rpm. Normal torque converter performance slippage of 100 rpm results in a loss of 1 1/2 mph through the trap.


Suspension & Tires

Type of rear suspension: This aids in identifying issues with your vehicle (or combination). Sometimes a performance decline is caused by the chassis rather than the transmission or torque converter performance.
