It does not. What is does do is improve engine operation by providing better fuel atomization which results in smoother operation of the engine throughout its operating range. In order for an engine to get better economy by adding fuel injection with NO other changes to the engine, the fuel injection would have to make it so that the required fuel to the engine for proper mixtures would be less, so less fuel is burned at the same rpm as when it was carbureted. This of course is ridiculous. Simply changing the way the fuel is introduced into the engine is not going to change the amount required for proper fuel ratio. Typically what you see happen, especially in cars is that the manufacturer, having added fuel injection and increasing their control over fuel delivery, will also raise the compression ratio, and add more timing advance, because they computer control the timing already, and have knock sensors to pick up on any detonation long before the human ear would ever hear it. This allows for the computer to then make the mixture go beyond the stotiometric or ideal mix (14.7 pounds of air to 1 pound of fuel for auto gas ) to get better fuel economy, but then as needed richen up and retard timing to protect the engine and still preserve performance, as in while accelerating. I worked in the auto industry for over 12 years as a performance technician, and found all this information very well documented in William Wynne's Corvair conversion book. The fuel injection systems that really add performance to the engine operation require being installed as a package to get that performance. The problem becomes the redundancy required for safe flight conditions in the event of the different types of failures that can occur, though they may not happen often, one has to be prepared for when that "one time" happens to you. Throttle body injection is a total waste of time, for its added complexity, fuel pressure increase over gravity systems or mechanical pumps, and its total reliance on electrical power. I have fought with alternator problems for 6 months, and I can tell you that I am very glad to have the Slick Mag and gravity feed carb, which guarantees I will keep running even with dead battery. A mechanical pump on a Corvair is a typical GM style mechanical pump capable of maintaining fuel supply even from the wings of a KR if the line is already primed and no high G maneuvers are performed. I have sat here and fantasized about how good my plane would perform with a sequential fuel injected engine installed, and if I lost that engine at some 4000 or 5000 feet that I would be fine to execute and emergency landing, no big deal. That is what we train for as commercial pilots. We CIF's are forever pulling our students engines at 3000 feet and making them find a suitable landing spot. Then the other day I had a low power situation on takeoff, where I was only climbing 150 fpm, and I felt like I did in a light twin engine plane on single engine, that I was going down, just where was I going to be forced to land. There was no where good, hangars, trees, houses, too small of back yards ( I am good but not THAT good ), city streets with power wires and traffic.... What if that was when the power died, the engine quit, the fuel pump died, or the ECM went into limp mode ( factory programming still has that mode for mutli failure detection ). My point is that it belongs in aviation, but with proper planning and correct installation. It is NOT as easy as ripping it out of the car/truck, and installing it in the plane as is. A proper electronic fuel injection aviation package must be engineered as a package into the plane. I believe Mark Langford went away from it for this reason, and I know from reading his manual that William Wynne did. It takes alot more know how of the system to package an aviation version properly than just cut and paste. Otherwise, I would already have done it!

Also, when you install the front bulkhead, install some threaded screws with nutplates to secure it. When I first installed my spinner I did so with just a pressure fit on the front bulkhead. When I removed my spinner after several hours of flight there was considerable galling from movement between the spinner cone and the bulkhead. Needless to say, I secured it when I mounted it again. I used #10 stainless screws ( round headed bolts) on the back plate and #8's on the front. I've had no problems since in the 130 hours of flight time. As to Orma's problem on the front bulkhead not fitting, when you order your spinner, you give them the prop thickness and they size the front bulkhead to fit the spinner for that prop. It won't work with any other thickness prop.

Here is what I did. I loaded the KR with 3 #40 bags of salt. One on the floor Fwd of the Fwd Spar and one flat on the seat and one leaning against the seat back for a total of #120. To that I added 10 of 12 gallons to the header tank. I am not sure yet what to do with the following information, but I weighed the tail at #57. Before flight, I ran the aircraft up to full power and attempted to lift the tail. With just me and fuel I could raise the tail anywhere after 2500 rpm. In this case I could barely raise the tail at 3300 rpm. Out to the runway, taxi was no difference, except for the semi fullness of the cockpit. I have a standard KR with 33.5 inches at the shoulder position along the top longeron. On the runway full throttle/full boost 3300 rpm/35 initial MP. The takeoff run was noticeably longer. To bring the tail up required increased stick force which was noticeable until lift off at about 65 mph. The take off run was not excessive. At 400 ft AGL, I reduced the boost and made my first turn. In this simple climbing turn, I could feel the increased weight. I kept the turn shallow since I do not know the stall numbers at this weight. I completed down wind and base. Balance and stability seemed the same. I did not feel the need to adjust trim. I decreased speed and at 100 mph I lowered flaps and started to slow down. The sink rate seemed a little faster, but again was well within limits and barely noticeable. Touch down and roll out were different. I prefer wheel landings and if the tail is low it usually takes minimal effort to keep it up as speed bleeds off. This time with the weight inside, keeping the tail up and the AC balanced on the mains was more work. My plan is to continue to fly with #120 until I become accustomed to the plane with that load. I will then add the other bags, one at a time.

Netters, I've been thinking the same thing for a while because I hope to take advantage of the prop bank next year when mine is flying (of course, now I'm jinx'd... :-). One way to continue to add money is when you borrow someone's molds (ie, Mark L's cowl molds, wheel pant molds, etc), drop a paypal to Mark Jones for $20 or so. Since we're saving significantly more money than that by using the molds, it seems like a small price to pay and especially with a cowl mold, you're getting close to potentially benefiting from the prop bank anyway. (Mark L- I hope you don't mind the reference). As a reminder, prop bank donations should be sent to: Mark Jones 615 Wexford Circle Wales, WI 53183 Paypal to: flykr2s@wi.rr.com Mark, Is there any place that lists how much is in the bank and what props there are available (if any)? Thanks again for facilitating this!
