What does the spring pressure in a blow-off valve do?

The spring inside your blow-off valve holds it shut against the boost pressure from your turbo. The spring's rating, like the 12 PSI in this red spring, determines how much boost pressure is needed before the valve opens to release excess air.

Can I use this spring in a different brand of blow-off valve?

This spring is specifically designed for the TiAL Sport QR blow-off valve. Using it in another brand's valve may not provide a proper fit or function correctly, potentially affecting your boost control.

What other parts might I need when changing the blow-off valve spring?

When changing your blow-off valve spring, it's a good time to inspect the valve's diaphragm and seals for any signs of wear or damage. You may also want to have the appropriate tools on hand for disassembly and reassembly, typically a socket set or Allen wrenches.

Product Details

This product is a 12 PSI red spring for the TiAL Sport QR blow-off valve, designed for a 1.0-inch port. This spring is what controls the pressure at which your blow-off valve opens to release excess boost from your turbo system. Having the right spring pressure is key to preventing compressor surge and ensuring your turbo spools efficiently.

TiAL Sport is known for well-built turbo components, and this spring is no exception. It's made to work specifically with their QR blow-off valve, ensuring a precise fit and reliable operation. The 12 PSI rating is a common choice for many turbocharged applications, offering a good balance between holding boost and releasing it when needed. If you're looking to fine-tune your boost control or replace an old spring, this is a solid option.

Remember that this spring is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific boost requirements and the TiAL Sport installation guide to ensure proper setup.
