FAQ
How do I select a torque converter stall speed?
- Choosing the right torque converter stall speed involves considering your engine's RPM range and camshaft duration. Stall speed is the point at which the torque converter transmits power to the transmission. Opt for a stall speed that matches your engine's torque curve and intended usage.
Do I need a new torque converter with a high performance cam?
- Yes, a high-performance camshaft often requires a new torque converter. Camshaft duration affects engine performance and RPM capabilities, necessitating a torque converter with a compatible stall speed for efficient power transfer across the RPM range.
Do rearend gears matter when selecting a torque converter?
- Rearend gears are crucial in torque converter selection. The gear ratio influences engine RPM and stall speed requirements. Higher gear ratios can accommodate higher stall speeds, while lower ratios may require lower stall speeds for optimal performance. Match the stall speed with the gear ratio for efficient power transfer.
What does a high stall converter do?
- A high stall converter allows the engine to reach higher RPM before engaging the transmission. This enhances acceleration, particularly beneficial in racing or performance applications where quick throttle response and higher RPM ranges are essential.
