Product Details
The Turbosmart Vee Port Pro Grey Blow-Off Valve Spring (TS-0205-3110) is a precision-engineered replacement spring designed for Turbosmart Vee Port Pro blow-off valves operating in low-vacuum environments. Featuring an extra-soft spring rating calibrated for approximately -6 to -7 inHg of manifold vacuum, this spring is particularly suited to supercharged engines and other forced-induction applications that produce minimal vacuum.
Proper blow-off valve spring selection is essential for maintaining responsive valve operation and reliable pressure relief. A spring that is too stiff for the engine's available manifold vacuum may prevent the blow-off valve from opening when required, potentially contributing to compressor surge, unwanted pressure fluctuations, or inconsistent valve response.
The Turbosmart TS-0205-3110 addresses this issue by providing a lighter spring option for compatible Vee Port Pro valves.
Manufactured specifically for Turbosmart's Vee Port Pro design, this grey spring allows owners to adjust their existing blow-off valve to better suit the vacuum characteristics of their engine without replacing the entire valve assembly.
This is especially beneficial for supercharged applications, engines with aggressive camshaft profiles, and custom forced-induction systems where available manifold vacuum is significantly lower than that of a typical factory engine.
The spring is manufactured to Turbosmart's specifications and is intended to provide consistent mechanical resistance during repeated blow-off valve operation.
Whether replacing a worn spring, correcting an incorrectly matched spring, or configuring a Turbosmart Vee Port Pro for a low-vacuum engine, the TS-0205-3110 provides an application-specific solution for maintaining proper blow-off valve response.

Understanding Blow-Off Valve Spring Pressure
A blow-off valve spring helps determine how the valve responds to pressure differences between the charge piping and intake manifold.
When the throttle closes, manifold pressure can drop while pressurized air remains in the charge piping.
The resulting pressure differential acts on the valve mechanism, allowing excess pressure to be released or redirected according to the valve design.
The spring provides resistance against this movement.
For proper operation, the spring must be matched to the engine's manifold vacuum characteristics.
A spring that is too stiff may prevent the valve from opening sufficiently.
A spring that is too soft may contribute to unwanted valve opening, leakage, or unstable operation under certain conditions.
Extra-Soft Grey Spring Configuration
The TS-0205-3110 is Turbosmart's grey extra-soft spring for the Vee Port Pro.
Its specified operating vacuum range is approximately -6 to -7 inHg.
This is substantially lower than the vacuum produced by many conventional engines at idle.
The lighter spring is intended to allow appropriate blow-off valve operation in applications where the available vacuum would be insufficient for a stiffer spring.
Supercharger Applications
Supercharged engines can have different manifold vacuum characteristics depending on the supercharger type, throttle arrangement, engine configuration, and operating conditions.
Certain supercharged applications produce very little vacuum at the blow-off valve reference source.
The TS-0205-3110 is specifically identified by Turbosmart for supercharger applications and engines with minimal vacuum.
Correct spring selection helps ensure the valve responds to the actual pressure conditions present in the system.
Spring Dimensions
Turbosmart's published spring specifications identify the grey Vee Port Pro spring as having:
Free Length: 81mm
Outside Diameter: 29mm
Vacuum Range: -6 to -7 inHg
These dimensions are important because replacement springs must fit the valve's internal spring cavity and operate within the intended travel range.
Do not substitute springs based solely on color or approximate physical dimensions.
Grey vs. White Vee Port Pro Springs
Turbosmart offers different spring configurations for its Vee Port Pro valve.
Grey Spring – TS-0205-3110
Extra-soft configuration.
Approximately -6 to -7 inHg operating vacuum.
81mm free length.
29mm outside diameter.
Intended for very low-vacuum and suitable supercharger applications.
White Spring – TS-0205-3106
Stiffer spring configuration.
Approximately -19 to -21 inHg operating vacuum.
108mm free length.
30mm outside diameter.
Intended for applications producing substantially more manifold vacuum.
The correct spring should be selected according to measured manifold vacuum and Turbosmart's recommendations.
Compatibility Considerations
The TS-0205-3110 is specifically listed for the Turbosmart Vee Port Pro.
It should not automatically be assumed compatible with every Turbosmart blow-off valve, including Kompact, RacePort, PowerPort, or other Type 5 configurations.
Different valves may use different spring dimensions and calibration requirements.
Confirm the exact blow-off valve model before ordering.
Selecting the Correct Spring
Before choosing a replacement spring, measure the engine's manifold vacuum at the appropriate reference source.
The measurement should be taken under the conditions specified by Turbosmart for spring selection.
Compare the measured vacuum against the manufacturer's recommended spring chart.
Do not select a spring solely according to engine horsepower, boost pressure, or turbocharger size.
Important: A blow-off valve spring's vacuum rating is not the same as the maximum boost pressure the valve can handle.
Performance and Reliability
The correct blow-off valve spring can help improve valve responsiveness and reduce unwanted operating behavior caused by an improperly matched spring.
However, changing the spring does not directly increase turbocharger boost pressure or engine horsepower.
The benefit comes from allowing the blow-off valve to operate correctly for the engine's vacuum conditions.
Common Reasons for Replacement
