Granatelli Motor Sports - Blow Off Valves/ Waste Gates

Granatelli Motor Sports’ Blow Off Valves and Wastegates category highlights a focused lineup of universal turbo-control components engineered to stabilize boost pressure and protect high-performance engines. Product options like the 50MM Water-Cooled Diaphragm Wastegate (540202), the 60MM Piston-Actuated Wastegate (540260), and the Ultra High-Flow 50MM Blow Off Valve (540201), each designed to vent excess boost, prevent compressor surge, and keep turbochargers operating efficiently under load. These components play a critical role in maintaining consistent power delivery, improving throttle response, and reducing stress on both the turbo and engine. When a wastegate sticks closed or a blow-off valve fails to open, the system can experience uncontrolled over-boost, turbo overspeed, or damaging pressure spikes. Issues that can lead to premature turbo failure or even catastrophic engine damage. By choosing durable, race-proven parts like the water-cooled diaphragm designs and high-flow BOVs featured here, you can be ensured that your turbo system stays reliable, responsive, and protected mile after mile.
