Why upgraded Supertech Valve Springs?

Supertech Performance upgraded valve springs are used in engines to enhance their performance and reliability, particularly in high-performance or modified engines. Valve springs play a crucial role in the operation of an engine's valvetrain by ensuring proper valve control and maintaining valve-seat contact.

The primary function of valve springs is to exert a specific amount of force to keep the engine's valves closed during the compression and combustion strokes, and to rapidly return them to the closed position after each opening. This ensures that the valves open and close at the right time, allowing for proper intake and exhaust flow and efficient engine operation.

When an engine is modified for increased performance, such as through higher rev limits, aggressive camshafts, forced induction, or other power-enhancing modifications, the demands on the valvetrain components can exceed the capabilities of the stock valve springs. Upgraded valve springs are designed to address these increased demands by providing several key benefits:

1. Increased spring pressure: Upgraded valve springs have higher spring pressures compared to stock springs. This added pressure helps prevent valve float, which is a condition where the valves are unable to fully close at high engine speeds. Valve float can lead to a loss of power, misfires, or even valve damage.
2. Improved valve control: By providing stronger spring pressure, upgraded valve springs improve valve control and reduce the likelihood of valve bounce. Valve bounce occurs when the valve rebounds from its seat due to insufficient spring force, resulting in inconsistent valve timing and potentially damaging contact between the valve and piston.
3. Enhanced durability: High-performance engines often operate under more extreme conditions, including increased RPM, higher temperatures, and greater stress on the valvetrain components. Upgraded valve springs are built to withstand these harsh conditions, offering increased durability and longevity over stock springs.
4. Compatibility with aftermarket camshafts: Aftermarket camshafts often have more aggressive profiles, requiring stiffer valve springs to manage the increased valve lift and duration. Upgraded valve springs are specifically designed to work with these aftermarket camshafts, ensuring proper valve control and preventing valve float.

It is important to note that when upgrading valve springs, other components of the valvetrain, such as retainers, locks, and possibly the cylinder head, may also need to be upgraded or modified to accommodate the increased spring pressures and prevent component failure.

Overall, the use of upgraded valve springs in an engine allows for improved valvetrain control, increased RPM capability, and enhanced durability, making them a vital component in high-performance and modified engines.
