Forge "Style" Blowoff Valve

This is NOT a genuine Forge BOV.  This is what is known in the business as a "knock-off".

This BOV attaches to the I/C piping via a hose barbed fitting at the bottom (25mm (1") diameter). The discharge port is also a very similar hose barbed fitting (25mm (1') diameter).

Also includes two additonal valve springs to accomodate a variety of boost pressures at which the BOV opens. This blowoff valve can easily be recirculated by attaching a hose to the discharge port, or can also be vented to atmosphere.
