Hey Paul; Appreciate the info. The FIRST consideration was the redrive, and after a lot of conversations with Tracy, Craig Catto, and Bob Wirth, we came to the conclusion that 450+ hp at take-off was o.k., then pull it back to 55-75% for cruise. That plywood firewall is a little undersized, and we have been fitting as we go along. But at this point, a couple more bubbles one way or the other, oh well. Guaranteed, it ain't going to look like a stock Legacy......(:-) Greg Ward Lancair 20B N178RG in progress ----- Original Message ----- From: <fpbjr2001@yahoo.com> To: "Rotary motors in aircraft" <flyrotary@lancaironline.net> Sent: Saturday, January 24, 2009 11:10 AM Subject: [FlyRotary] Re: HP was : Mark's BBQ Run / 20B numbers greg i do not know what you want but here goes. the idea with the engine was to have the most hp with the least amount of boost so the the turbo would not work very much so it will last longer. i feel it will fail first in the system. the engine is street ported and the turbo is a to4 (.96 cold side) with 3 lb. spring so the engine should turbo normalize at 300-330 hp. i have a bypass regulator so i can adjust boost pressure up to higher levels. if i get this checked out i'm going to add a pop off at 8-10 lbs so i can't over boost the system. i don't know if you have thought but the limiting factor is the gearbox. tracy says 300 hp continuous. these numbers are Conservative. but i feel we are in territory that has not been tested very much. beautiful work on your engine. i have one question. are you sure your intake is low enough to clear the cowlng. i had to redo the intake 3 times to get it low enough to clear my cowling. beautiful work! paul brannon N117ES --- On Fri, 1/23/09, Greg Ward <gregw@onestopdesign.biz> wrote: From: Greg Ward <gregw@onestopdesign.biz> Subject: [FlyRotary] Re: HP was : Mark's BBQ Run / 20B numbers To: "Rotary motors in aircraft" <flyrotary@lancaironline.net> Date: Friday, January 23, 2009, 8:35 PM Hi Paul; I would be real interested in what you've been doing, as it sounds close to what we are trying to accomplish. Any info would be appreciated, and as we finally get on the dyno, we will do the same.
