Synapse Universal pull-type blow-off valve design that eliminates leaking by seating the valve more as boost pressure increase. Each assembly is pressure tested to 100 psi prior to leaving the factory. Interchangeable inlet and discharge flanges allow various adapter and kits for many popular applications. Synapse Engineering Synchronic Blow-Off Valve is a fast-acting design that functions as a blow-off, diverter (DV)/bypass and even a pop-off valve. The patented (6,863,260) design eliminates the diaphragm with a multi-tier piston actuator that equalizes the force required to open the valve at any boost pressure. This design is intended to significantly reduce or eliminate compressor surge and will not leak boost.

Features:

• Innovative Piston Actuated Design Based on the Patented Synchronic Technology
• Absolutely No Diaphragm
• Pull-Type BOV designed to Stay Closed Under Boost
• Detachable Re-Circulation Discharge and Interchangeable Flange

Includes the 16003A Blow-Off Valve and the 16017A adapter flange and o-ring for Mazda only. A few additional parts may be required for installation. Please see the installation document posted by Synapse for more details:
