Bought this off ebay to run as a bypass for a supercharger project. Went in another direction, so I don't need it. It is brand new, in the box. Aluminum construction, aluminum inner piston, the ports are 1" diameter, very large, much larger than the Bosch OEM valve. Comes with 3 springs to adjust cranking and full open pressures. Can be used as a vent to atomosphere BOV or a recirculating bypass valve. The spring specs are as follows:

Crack/Full Flow

Green 10 lb 15 lb

Black 15 lb 17 lb

Silver 12lb 15 lb

I'll include about 3 feet of 1" heater hose as well since I don't need it now.

I paid around $60 for just the valve. Again the valve is brand new in the original box, plus springs and 1" hose and some 1" hose connectors.

$40 for everything to your door.

 

Couple photos I just took this afternoon.

 

Any idea for a source for more springs with different load characteristics?

 

There's a company that makes a similar valve, Forge something. They might.

 

Sweet, this is a counterfeit of one of our valves!

God bless ebay.

 

Either way, it's a pretty darn nice valve.
