@swooshdave given the amount of time and effort you have put into improving the breathing side of your engine, I was surprised to see your reed breather on the end of a piece of rubber hose.
Surely this is a great opportunity to get the valve close to the engine?
My view of your current setup is:
- the hose is acting as a heat insulator - when the exhausted gas hits it, you’ll get mayonnaise as the hot air with it’s air-bound oil hits the colder component.
- the give and flex in large diameter rubber hose will negate many of the benefits of using a reed valve. We are trying to get these things buzzing and resonating for them to work at their maximum efficiency, and by putting a big buffer inline where the air can be easily compressed is somewhat defeating the object.
Maybe one of the breather experts like
@comnoz and
@jseng1 can chime in here?
I wasn’t going to post this, as you get plenty of feedback from others, but this has been on my mind.
