Priority breather valve
Here are some pictures of my priority breather valve.
The complete valve is made out of aluminum.
The rubber sealing on the valve, is made out of rubber gasket on tube, for use in engine.
You will need a turning-lathe to make the priority breather valve.
The measurements on the priority breather valve are up to you to decide,
depends on the space you have and how much extra air you need on low rpm.
When you are finish with the priority breather valve, mount it on the plenum and
pressurize the plenum to see if the valve is leaking, use about 1.bar
My priority breather valve is leaking up to about 0.10 - 0.15 bar
after that it seals properly.
The spring should be very soft, it should barely hold up the valve.
