What is the purpose of changing the wastegate spring?

Changing the wastegate spring allows you to adjust the maximum boost pressure your turbo system will produce. A lower PSI spring, like this 5 PSI version, will limit the boost to a lower level than a higher PSI spring.

Product Details

If you're looking to dial in the boost pressure on your turbocharged vehicle, this Turbosmart WG40 5PSI Inner Spring is a key component. It works inside Turbosmart's Ultra-Gate38, Comp-Gate40, and Hyper-Gate45 external wastegates, as well as their Internal Wastegate Actuators (IWG-75). Getting the right spring rate is crucial for controlling how much boost your engine makes, and this 5 PSI spring offers a specific setting for tuners who need precise control.

This spring is made from well-built materials to ensure it holds its tension and performs reliably, even under the high temperatures and pressures found in a turbo system. By swapping out the existing spring for this 5 PSI version, you can effectively lower the maximum boost pressure your wastegate will allow, which is useful for applications where you need less boost than the stock spring provides, or when fine-tuning a specific engine map. It's a straightforward way to adjust your turbo system's behavior.

Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific tuning requirements and consult with a professional if you're unsure about making adjustments to your boost control system.
