Universal Auto 25mm aluminum racing turbo charger Blow Off Valve/blow dump/blow off adaptor (BOV)

High quality auto racing turbo aluminum blow off valve/blow off adaptor/blow dumpDescriptionNew generation of Blow Off Valves which has a Floating Valve, it is this breakthrough in design that produces quicker valve response, increased valve vel, and improved resistance to premature valve lift and boost leak. The unique floating valve design incorporates a revised adjustable spring system and diaphragm ventilation, while maintaining the advantages of a standard BOVs push valve structure and heat resistant silicone diaphragm.This allows the springs and diaphragm to better control the valve and boost. By locating one spring under and keeping one over the diaphragm, it es the need for spring pre-load le dependent on idle and light boost situations and more on keeping the valve closed under boost.This is the preferred venting solution for street s and drag racers. Big flow and even bier sound. Easy to install and set up.Features- prevent premature boost leakage- Hard annodized machined aluminium valve for increased performance and bility- Bellofram diaphragm ensures proper valve movement with incredible response- Spring increases valve speed for fast response- Adjustable spring rate to suit a range of applications
