Check the lines to the sending unit and the manifold pressure gauge first before assuming it is the super charger in the accessory case. doc -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of Yakbaas Sent: Tuesday, September 07, 2010 2:26 AM Subject: Yak-List: Low Boost?

From: "A. Dennis Savarese" Please explain what to mean by 95-100 mm of boost. The normal manifold pressure for a 360 HP M14P at sea level (important) is around 880-890 mm. There is no sender for manifold pressure. It is read direct from the supercharger. At sea level on a standard day, the manifold pressure instrument should read 760 mm. Therefore the total boost AT SEA LEVEL is about 120 mm.

Dennis Savarese" Subject: Re: Yak-List: Low Boost? 760 mm manifold pressure is with the engine off. 880-890 mm is at wide open throttle typically only seen on takeoff.

From: "Yakbaas" I have 735mm with engine off and only get 830mm on take-off roll.Still get 99% on rpm. Had 2 take-offs in the last 20 hours where the rpm "hunt" between 99% and 89% (WOT),came back to 80% and still hunting 5% up and down.Only when I set 70% and 700mm it stabilized.Never done it again! I don't think the 2 are related though.
