Netters, I'm looking for a cleaner way of mounting a 4 in vacuum venturi. It appears that Steve Jones' setup is effective, as far as providing ample vacuum, but I think there's gotta be a cleaner way to do this. Has anyone placed the venturi inside the cowl and provided an inlet and exhaust for it? Inside the cowl would provide several advantages: 1.) Less drag 2.) Less prone to icing 3.) Ram air from prop would provide vacuum signal sooner?
Could a vacuum pan set-up provide enough vacuum to run vacuum powered instruments? A Smog check valve is placed perpendicular to the exhaust flow, with the check valve opening facing downstream. This provides enough vacuum to evacuate the crankcase of fumes, enough power to run instruments? If both of these systems were plumbed, would it have enough redundancy to use with out electrical instrument back-up? What are other KR's that flying (or close to it)using? ===== Scott Cable KR-2S # 735 Wright City, MO s2cab...@yahoo.com __________________________________ Do you Yahoo!?
