What base boost pressures can I achieve with the included springs?

The wastegate comes with 5psi and 10psi springs. You can use them individually for 5 or 10psi, or combine them to achieve a base boost pressure of 15psi.

Can I achieve higher base boost pressures than 15psi?

Yes, additional springs are available separately. By combining the included springs with separately purchased ones, you can achieve base boost pressures ranging from 5psi up to 22psi.

What makes this wastegate resistant to sticking?

It features an internal shroud that protects the valve stem from excessive heat. This design helps prevent carbon buildup, which is a common cause of sticking in high-temperature exhaust environments.

Product Details

The body of this GFB wastegate is investment cast from 253MA chromium-nickel stainless steel, a material chosen for its ability to handle the extreme conditions found in high-boost exhaust systems. This robust construction, along with a one-piece stainless steel valve and a Nomex-reinforced diaphragm, means it's built to cope with harsh environments and high temperatures.

This 44mm wastegate uses a V-band inlet and outlet, making it directly compatible with Tial MV-R flanges for a secure and easy connection. The internal shroud is designed to protect the valve stem from excessive heat and prevent sticking caused by carbon buildup, a common issue in these applications. The actuator housing is CNC machined from billet 6061-T6 aluminum for durability.

You can fine-tune your base boost pressure using the included springs. It comes with 5psi and 10psi springs, which can be used separately for 5 or 10psi, or combined for 15psi. Additional springs are available separately to achieve even more base boost pressure options, including 7psi, allowing for combinations up to 22psi. This wastegate is also notably compact, making it easier to fit into tight engine bays.
