WG40 Compgate 40mm Ext Wastegate 14 PSI Black

The WG40 Compgate 40mm Ext Wastegate 14 PSI Black from Turbosmart USA is a precision boost-control component designed specifically for turbocharged and supercharged vehicles. It is engineered for builders and enthusiasts who require reliable and adjustable boost management across various RPM ranges, making it suitable for street builds, track applications, or high-output engine platforms.

This external wastegate features a poppet-valve mechanism that opens at the set pressure differential, effectively venting exhaust gas around the turbine wheel to prevent overboosting and potential turbo damage. With a 40mm valve seat and a compact external housing, it allows for flexible exhaust plumbing integration and precise boost targeting. The robust aluminum construction and black powder-coated finish enhance durability and resistance to corrosion in demanding underhood environments.

The adjustable nature of the WG40 wastegate, through external spring adjustments or alternative springs, provides tuning flexibility for various applications. This makes it particularly beneficial for EFI-tuned platforms and custom engine builds where OEM boost control may not suffice, especially in setups like LS turbos and 4-cylinder engines.
