GReddy Type R11 Wastegate 47mm Valve (11501531)

This Greddy wastegate regulates boost pressure by diverting exhaust gas from the exhaust manifold before it reaches the turbocharger, reducing its workload. It's essential when using a turbocharger without an actuator valve. The range includes the Type R with a 50mm valve diameter, the Type C with a stainless steel housing and heat insulator also with a 50mm valve diameter, and the Type C High Flow with a 60mm valve diameter. Different models are available depending on exhaust pressure and desired boost levels. A reinforced spring is also offered for increasing boost pressure. This lineup meets the demands of users pushing the limits on closed courses.

Vehicle Fitment:
Universal

Features:
• Each unit is fully adjustable and rebuildable, available in four sizes with various spring rates
• Type R11 1.1-1.5 kg/cm2 (15-21psi) Spring Rate
• GReddy wastegate valve has a large capacity and excellent durability, and promises stable boost pressure control.

Importance of a Wastegate:
A properly sized wastegate is one of the most crucial components in a well-designed turbocharged engine setup. A wastegate that's too small can cause boost creep, while one that's too large may lead to increased boost lag and reduced performance. Our GReddy external wastegates are crafted from top-quality materials to ensure stability and durability in turbocharger boost control.

Notes:

• When increasing the turbine capacity, the actuator method will not have enough capacity and will not be able to release the increased exhaust gas pressure.
• Due to this item being in high demand, please call to confirm availability prior to ordering
