References: In-Reply-To: Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Return-Path: crobinson@rfgonline.com X-OriginalArrivalTime: 19 Mar 2004 15:55:41.0967 (UTC) FILETIME=[A1A449F0:01C40DCA] How are people splitting air from scoops into intake, cabin cooling, and radiator feeds? Are you just partitioning the scoop into separate output feeds? If so, how large should I make the feed to the intake air for the engine, and should it have a bypass to allow unused air to escape, or should I just feed it to the engine compartment/cowl and let the intake pull out what it will? I'm planning a single P51-style scoop that drops below the boundary layer, and I'd like to avoid having separate/extra armpit or similar scoops for other air supplies. Thanks, Chad
