GVW EXTERNAL WASTEGATES
GARRETT VENT | EXTERNAL WASTEGATES
High flowing external wastegates for turbocharged racing and performance engines
G
arrett Vent | External Wastegates regulate turbocharger
shaft speed by venting exhaust gas around the turbine
stage of the turbocharger. CFD optimized design maximizes
flow and delivers optimum boost control. Advanced thermal
optimization increases durability of the diaphragm. The cap
design makes spring changes and serviceability of the entire
GVW lineup easier and more reliable to perform.
