Selecting the correct wastegate spring is critical for achieving stable boost control and reliable turbocharger performance. This Turbo Care Wastegate Spring Chart provides a general guide to common wastegate spring colours and their corresponding base boost pressure ranges.
Wastegate spring pressure determines the minimum boost pressure your turbocharger system will operate at before any electronic boost control is applied. Choosing the correct spring setup helps improve boost stability, turbo response, and overall engine performance.
This chart is intended as a general reference guide only. Actual boost pressure can vary depending on:
- turbocharger size
- exhaust manifold design
- wastegate size
- boost control setup
- engine configuration
- exhaust backpressure
For high-performance or motorsport applications, proper tuning and boost control calibration are strongly recommended.
