KR> 'Rectangular' boat building
I checked out bobs photo's, seem,s he made a hard job harder. I didnt worry about 'squaring the sides, just ensured the sides were equally spaced and angle cut the 'bulkhead' members to give the correct shape (yes the top longerons do 'banana slightly but why should that be a problem? The idea of foam sound insulation was in my plan too untill I discovered that in the event of fire ,toxic fumes could overcome you before escape (in event of a crash). Not a pleasant thought?

Ha ha, Seems no one has respect for the ones on ebay. http://www.car-forums.com/s7/t248.html Though there are some very valid statements when you think about it, then there is Tomas Knight, seems his name is all over the place when it comes to elec turbos, but his units are 2500 bucks. http://www.boosthead.com/product.php There is alot of good information, though it seems to validate the point, you can't run the turbo at the rate it needs to run to be effective with the power the alt will produce. It can only be run for short hops (good for take offs and maybe stalls, to pull out of them). Though 2500 for a good elec turbo system is a bit out there, sicne it requires extra battries it reduces the weight savings drastically. Seems the cheaper ones are not very valid as they have no tests I could find to back up thier claims. Here are some of the other people: http://www.autoaccessorystore.com/product/MimoUSA-Electric-Supercharger/Default.aspx?dr=1 http://www.electricsupercharger.net/ One would think for 2500 it better work, but I could see alot of people tempted by $100 turbo to just try it out.

KR> To Turbo or not to Turbo that is the Question
Steve & Jeff are thinking positive, my cynical comment on electric 'turbos' failed to convey my approval of conventional exhaust turbos. My current plan is to installa l a normally aspirated EA81 which I have, as a possible forerunner to a factory turbo fuel injected EA81(comp ratio,pistons, valves etc should be ok, its the cooling side to take care of - space & weight would be marginal on a KR though?). with a new plane in the air who needs possible extra problems to sort out first few hours up? The other concern is my caution regarding anythying computer/electronic going wrong at even 1000'. We have a lot of hills & mountains here.But I still hanker for a corvair core engine to use - another plea to anyone who can help get one down to NewZealand - corvairs are rarer than rockin horse turds downunder! - Original Message - From: "Jeff York" To: "KRnet" Sent: Tuesday, January 04, 2011 6:20 AM Subject: Re: KR> To Turbo or not to Turbo that is the Question I, as well as Steve (as he stated) would enjoy hearing more about the positives on turbo charging too. That said, I want to say that I did not want to come off sounding negative, I just wanted to point out my concerns about turbo charging from my experience's in high performance turbo charging. There are so many benefits to turbo charging an engine from performance in power and fuel economy. Yes I said fuel economy and what I meant by that was you can run a normally smaller displacement engine to gain economy while getting the benefits of additional power by force feeding air/fuel via the turbo. My problem was I never could keep my foot out of it to really see the fuel economies but they are there. Also, my experience was performance related and not of the altitude normalizing that would be associated with aircraft turbo applications. However, some of the same issues apply. I pointed out, and Steve and others pointed them out as well. The main concerns I would have are oil and engine temps due to the very high temps a turbo can achieve. As I recall 1600 degrees F. As Steve pointed out, I would never consider a turbo without a intercooler. An intercooler is used to cool the turbo charged air fuel after it goes through the turbo and before it enters the combustion chamber. Do not mistake the idea that an intercooler is for cooling the turbo charger. Its not. That will be the job of your over sized oil cooler. When the engine in a turbo charged motor is shut down, that 1600 degree turbo (which is oil cooled) will act as a furnace to cook the remaining oil in the turbo. This will effectively coke the oil. This is why normal shut down of a turbo charged motor is not recommended. Its why turbo timers are used to circulate that oil after engine shut down. I know the Dragonfly guys and Tri Q guys did a lot of turbo charging of the Subaru motors and some of the Corvair guys had been looking into it or have done it. But I believe weight and engine life issues may have slowed down or halted the use and development of those turbo applications. One more thing. It was my understanding when I did turbos on performance applications that you did not just slap a turbo on any engine. Don't put ten pounds of boost on a 9 to 1 or 10 to 1 compression motor and expect it to hold together very long. You will effectively have a 19 or 20 to 1 compression motor. These are diesels. That kind of compression will blow up a motor. Also, make sure you have the right exhaust valves to handle a turbo or you will be burning them up. Not fun pulling off to the side of the road at 10,000 feet when you eat a valve cook a piston or blow a head gasket. It was a lot of fun doing turbo apps in automotive applications. Computer controlled air fuel metering, precise BOV/ Waste gate control, air/fuel mixture control and other systems allowed reliable power gains. I am not sure I have seen anything better than old unreliable mechanical systems available to do this on a VW motor. But what the William Winns and MJ's and ML's are doing with the systems they have available on Corvair motors would to me seem to be the better platform in which to start a turbo project. I love my GPAS VW and all that Steve Bennett has done. But the fastest way for me to mess up all that reliability is to slap a turbo on my VW motor without finding out if and how it can be done reliably. OK, I have ranted enough. I too want to hear from those that have done it so as to get the positive and learn how. Thats what this is all about. Sorry for running on but, I hope I was informative in some way as to the how what to look out for and what not to do. I would love to get 70, 80 or more horsepower out of my VW motor and if I could add a turbo to it and get reliable life out of it, I would do it. But, in my opinion, it might make more sense to look at a Corvair that can get 100 hp or one of these 23xx VW motors. But, lets hear from the ones who know how a

KR> Confession
Jack Thanks for your prompt reply. Yes I have tried William but he apparrently only supplies on condition of receiving replacement cores. I have tried phoning & emailing but it appears he is too busy to be involved. I have even purchased the construction manual but it is of no use without an engine to construct! The shipping costs would have to be checked out but from Tennesee I would think they would be similar to Florida. Do you have the 164ci cores or? Serial numbers? The construction manual gives the numbers preferred. I dont know what the 'failure' rate of core engines are but I believe most are usable. If you dont want to quit your engine thats OK but I thought I may also get a response elsewhere on KRnet. With shipping costs we have to bite the bullet if it is affordable becauseof distance. hope you dont dissappear from KRnet with the Grumman project though.

KR> (no subject)
having invested fair bit of time (&dollars) into my KR2S project, I'm starting to wonder if I made the right choice. There has been a bit of diiscussion about landing taildraggers on here,is it that difficult? how do they compare to trigears? As an inexperienced pilot ,have I bitten off more than I can chew? I have always liked the clean low wing design & the KR construction method, but are high speed planes a bit much to start out in. I have significantly increased the tail areas to give more stability, & plan on longer wings. Would I be better to put the KR on hold & go to a STOL type (Roger Mann Storch?) to gain initial experience? A lot of the componentry can be used on a 2nd project. Any thoughts appreciated.

KR> Jabiru 3300
I dont understand the "excess" power thing, but down under ( New Zealand), the Jabarus are treated as a bad joke, beautiful , light, have the grunt sure. But how many issues do they have? valve & head failures, (known to have dropped valves through pistons) causing engine outs, probably the wost are the poor flywheel dowling design which has caused countless flywheels to part company with the crank (great for ignition timing!) These engines have had hundreds of mods from original & have they got it right yet?

KR> Gathering
just reading about the extended take off & landing distances as compared to the claims made on the original sales blurb, how do the Corvair powered KR's compare? - Original Message - From: "Mark Langford" To: "KRnet" Sent: Monday, September 19, 2011 9:49 AM Subject: Re: KR> Gathering Yep, another great Gathering. Joe, Mark Jones, Brad Stone, and I all left the Gathering yesterday to beat a weather system that will likely continue to dump rain on MVN through today and some of tonight.. It turns out I could have waited until early this morning and still made it fine, but that wasn't the recommendation of the weather briefer I talked to yesterday afternoon. Sorry we missed the banquet. I noticed yesterday there are some folks in attendance who didn't do much mingling or talking, just stayed on the periphery at a distance. At the same time, the pilots and some of the "in" crowd spent a lot of time standing around joking and carrying on with each other, and I'm as guilty as anybody. On the flight back, it occurred to me that next year we should try to be better about mixing it up with folks who we don't recognize, and even some we recognize but don't know their names, what they're building, or what we can do to help them get their KRs in the air. That's one of the main reasons we hold the Gathering, right? I talked to Joe last night and he mentioned that we really should do more to promote the Gathering, such as publish it in Sport Aviation and other magazines and internet sites and lists, as well as local airport flyers, etc, with sufficient advance notice to let builders and pilots plan on attending. Mark Jones remarked at breakfast yesterday that next year was the fortieth anniversary of the KR, and we should strive for 40 KRs to fly in. There are a lot of KR builders and pilots out there somewhere... we need to find them and talk them into showing up next year. I was not surprised to hear that MVN was voted to host the Gathering again next year, and you have to admit it's difficult to imagine a place that's better set up to host it. Thanks again to Larry Flesner for doing a lot of the legwork, and Chris Collins providing the airport facilities and continuous support as well.

KR> Reading related to Cranks and flywheels
Spose its too common sense for most but 'if its not broken dont fix it" thinking applies in a lot of cases! flywheels are needed (as are harmonic balancers). The suggestion from Phil re belted reduction drives is partly correct as to allowing engines to produce the designed rpm/power, but belted reductions impose side thrust on the rear main bearing. Neil Hintz (www.autoflight.co.nz) produces a PSRU that uses a flexible coupling to isolate the engine fom the reduction gears which seems to be a sound engineering approach. (the PSRU would provide some measure of flywheel inertia effect I would think). Just more fuel for the fire of debate!
