Things to Know Before Purchasing a Synapse Compressor Valve

A

Before purchasing a Synchronic valve there are several facets of the product that you need to know and understand that differentiate it from any other product on the market today.

  • There is no diaphragm.  There is only a stepped piston with o-rings.
  • When installed, the valve will perform according to the signal that is connected to the two ports A, B or A+B.  Vacuum will open it, boost will close it, and without a signal it will be closed.
  • There are two actuation ports on each valve, Port A (closest to center) and Port B (further from the center).
  • When the valve is installed, it will be open under vacuum.  This includes idle conditions.  This is by design, this is not a leak, the valve will close by -4" of vacuum and will seal over 100+ psi of boost.
  • If you have an MAF (Mass Air Flow) equipped vehicle, you will need to recirculate the discharge of the Synchronic valve.  This cannot be done with certain valves such as the Radial R35 and R55.
  • The valve will operate with any OEM control system.  It can be controlled by the OEM ECU and solenoid.
