But not if your engine is burning Jet A! I don't think it would last that long! In a V35B this fall headed to CO from Madera, CA at 11,500 ft. we were doing 159 kts TAS on 10.5 gph, full throttle at only 2200 rpm and 30F lean of peak EGT! That's with about 150 hp or 50% for the IO-550, 300 hp engine. At these slow engine and prop speeds the efficiency of the fuel injected IO-550 Continental engine and Hartzell blended airfoil prop cannot be beat. With 115 gal useable we could have gone to Colorado Springs and back without refueling (about 10hrs of flying). That really helps when you have gas at your own strip that costs only $3.00/gal! Now if you had an angle valve cylinder engine with the same compression ratio and fuel injection, Gary, I'll bet you would be doing the same speed as you now are and burning at least 1 gph less fuel, probably more. The big issue is the engine specific fuel consumption decreases considerably and prop efficiency increases as the engine speed decreases, especially when you operate way on the lean side of peak EGT with balanced fuel injectors. I'm not trying to detract from your comparison with the Diamond twin. In fact I applaud your efforts and achievement in what your have done with the cowl, etc. on your Tiger. Just bragging a bit, I guess, about the efficiency of a stock Bonanza airframe and engine when operated properly with balanced fuel injectors.

Just remember all the Tigers would say is GR-R-RRRR! FLYV35B where does your allegiance lie? Please do tell, do you show your Tiger allegiance on the Bonanza net? Or has that constant V-tail yaw wobble got you all mixed up? ________________________________ Message 3 _____________________________________ Time: 08:03:32 AM PST US From: "flyv35b" Subject: Re: TeamGrumman-List: Diesel Pretty Good! Who knows where my allegiance lies, probably with whatever does the best job for the mission at hand! For right now my AA-1C with the O-320 engine satisfies part of the mission, but I'm gravitating toward an RV down the road, or maybe even a Lancair Legacy! Maybe even the new German REMOS LS aircraft (talk about efficiency) with a full feathering prop or a motor glider. I try to be objective about whatever I am comparing in contrast to some who think "and God only created Grummans". And what about the former Tiger owner gal who showed up at Fredericksburg this year with her brand new RV-10, should she be tarred and feathered and run out of town?

With a limited amount of money to spend on aircraft we all have to make "tough" choices. Money is almost always going to be part of the decision making process on what or how many aircraft to own. ----- Original Message ----- From: "923te" <923te@cox.net> Sent: Tuesday, December 05, 2006 8:14 AM Subject: Re: TeamGrumman-List: Diesel > > Pecan Plantation neighbors still hear Debbie morn the loss of her > grumman:) > > Only sold to finance her RV10... > > > -- > > ________________________________ Message 6 _____________________________________ Time: 02:10:06 PM PST US Subject: Re: TeamGrumman-List: Diesel From: teamgrumman@aol.com I'm all for the Legacy. AND, I was looking at the Remos a few days ago. Cool little plane. I'd also be interested in another Citabria. If I only had some rich relatives that would leave me a LOT of money. -----Original Message----- From: flyv35b@minetfiber.com Sent: Tue, 5 Dec 2006 8:03 AM Subject: Re: TeamGrumman-List: Diesel Pretty Good!
