What size stall converter do I need?

What size stall 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.

What happens if your stall converter 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 a stall converter make you faster?

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 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.

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.

What is the difference between a low stall and a high stall torque converter?

For many street trucks that are used for towing, daily driving, and performance, owners choose a lower-than-stock stall converter. While high-stall converters are the ticket for racing, they generate lots of heat due to high slip percentages and can create a huge rpm drop when lockup is engaged.

What is the point of a stall converter?

When your torque converter prevents the power transfer from your engine to your transmission, it increases the engine’s RPM stalls. For example, when you press down on your gas pedal, the stall speed is the gap between where your vehicle ideals and begins to move.

What does a stall converter feel like?

The biggest thing you will notice is on the high way before stall speed rpms are reached. It feels like a manual transmission with the clutch barly pushed in. You definatly need a trans cooler, because the extra heat a higher stall speed convertor produces,, from slippage.

Is a low stall torque converter better for towing?

For many street trucks that are used for towing, daily driving, and performance, owners choose a lower-than-stock stall converter. 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 does a low stall converter do?

With a lower stall speed, less time elapses before the motion energy of the impeller is converted to motion energy to drive the turbine, so the transmission runs cooler and lives longer. What many people don’t know is that the torque converter is a tunable device.
