Bob, I think that we routinely change the vertical CG by more than the 2" thrust line difference would compensate for. Putting all your fuel in wing tanks rather than in a header tank would probably offset the difference, and that's been done many times. I wouldn't worry about it. Just make it fit. I plan to lower mine at least that much.

I have a junker EA-81 that I got last week. Today I pulled the intake manifold off, along with all the plumbing. The alternator sticks up 7.5 inches from the crank, and the distributor sticks up 8 inches at the top of the wires, which have 90 deg boots already. The thrustline is only 6 inches even from the top of the forward deck, so there's where the 2 inches is recommended, I guess. Two inches offset downward would screw up the look of the cowl, so I would never do that because the KR-2S cowl is sooooo gorgeous. One other reason is that the oil pan already would protrude one inch throught the cowl, and will have to be sliced off at the front bottom and rewelded to shape already, and 2" offset vertically would greatly reduce the amount of oil the pan would hold due to even more profile reduction. I think these problems have never surfaced before because the redrives have a lot of nice space behind them already for these accessories, and the one DDTS detailed on the web is in a Dragonfly, which has a lot more clearance. One thing recommended to me was to cut the cowling length at the spinner by 2 inches, and use a larger spinner. This is to prevent having to use a prop shaft adapter longer than 6". Have you seen Roger Enn's website at http://www.si-inc.com/subaru/direct81.htm ? If you want to do a DDTS you should get on the Airsig mailing list too. They're highly devoted to Soobs and will steer you in the right direction. One thing I'm considering is using a dry sump, with an NSI gear reduction which has a few inches offset, unlike the belt drives, which have about 6 inches usually. The EA-81 turbo with the NSI reduction puts out 135 hp. Of course you're upping the weight with the reduction. - -Tom Kr2dream@aol.com wrote: > I am one of the die-hards who is sold on the idea of using a soob on my KR-2S. > I have been told by people who are supposed to be engine professionals that > the direct-drive soob must be mounted with the thrust line 2 inches below > where the VW crank center would be.

Maybe the Soob I have is different than the rest? The Dragonfly appears to have a lower crank center than the KR-2S. I really wish I could use that inexpensive prop hub adapter on my DDTS but it's just too short. I need a six inch extension, and the cowl may need to be cut back. That's what a KR-2S with the DDTS required. Now I'M considering building the motor mount to have the engine two inches lower, and cut the rear edge of the cowl to line up at the spinner as usual. The cowling would be angled down two inches, I'd have two inches less prop clearance, but I'd have two inches better visibility over the cowling. I may not even have to cut the oil pan to fit inside the cowl at that new angle. When I responded earlier I thought that Bob was planning on keeping the cowl straight and reshaping the spinner area two inches lower. My bad... I assumed... Bob, is this what you were thinking? - -Tom Micheal Mims wrote: > Tom Andersen wrote: > > > <<< > lot of nice space behind them already for these accessories, and the one DDTS > > detailed on the web is in a Dragonfly, which has a lot more clearance. >>>> > > Not true dude!

You are planning on running the prop off the tranny end aren't you? I don't understand how someone can fit that engine in a Teeny Two and it wont fit in a KR. Also there is a lot more the 6 inches available from the thrust line to the top of the T-deck. I would say closer to 8 or 10 inches if your thrust line is at the bottom of the top cross member. Oh well I guess you have the engine in your garage so you should know better than I if it would fit. All I know is there are two Dragonflies in my hanger and I know for a fact you cant fit an O200 in one but a KR2S will swallow one whole! :o) On the prop hub I had planned to use the one on the engine page with a standard SAE bolt pattern so I could bolt up a prop extension from AS&S. ------------------------------ Date: Tue, 30 Jun 1998 15:07:22 EDT From: Kr2dream@aol.com Subject: KR: Soob Question explanation Sorry guys - I should have explained further when I submitted the question regarding the vertical offset mounting. In building my KR-2S I received a VERY nice gift from my mom out on the west coast. She has flown with me before and said she wanted me to have a "factory built" engine for the plane I was building. She said to order the 100DT from Air-Ryder and she would pay for it! WOW! Bud Clarke was a joy to work with and matched the mount to my cowl which I had shipped to him. When I received the engine last friday I was shocked to find the drive centerline 2" low. The 2" is required to fit the engine in the cowl. Bud has advised me how to reform the lower cowl so that the sleek lines are again attained. There is plenty of room in the cowl for the radiator below the engine. The sump doesn't even come close to the lower cowl section. The engine is BEAUTIFUL! The dry weight of the engine with prop extension, turbo and intercooler is only 184 pounds. It is rated 100 HP to 19,000 feet. Should be a nice match for my KR. The only drawback is that is is expensive. I was just worried when I saw the vertical offset as I didn't expect it. I appreciate all the responses. For anyone interested I will be bringing the engine to display at Oshkosh. I have a new scale coming in tomorrow and should be able to post the entire firewall-forward weight including the 3-blade prop.

I'm going to build a 100DT myself, but if I had the money, I'd love a FF package that weighs 184lbs and puts out 100hp. -Tom Kr2dream@aol.com wrote: > Sorry guys - I should have explained further when I submitted the question > regarding the vertical offset mounting.

This will be just enough to clear the distributor. The alternator is a severe problem since it is not near the point where I have the 8 inches. The alternator is practically directly behind the right rocker cover. I will have to use some kind of lighting coil on the crank pulley or maybe a small, narrow generator, or perhaps mount the alternator under the engine. The alternator truly will be a problem. - -Tom Micheal Mims wrote: > Tom Andersen wrote: > > > > Mike, > > Maybe I have mismarked the position of the thrust line but I thought it was at the top of > > the upper crossmember. > > -Tom > > I don't know where it is, do the plans even say?

Mark, That's the best plan for VW power I've ever seen. You maintain the low cost crank and parts, get to use an inexpensive and reliable distributor, pull power off the correct end, absorb the prop loads with the prop adapter's bearings, and have the great case strength and durability of the Type 4. The engine will not know it's in an airplane, except for the 200mph air cooling it! :) What pitch prop do you plan to run on a 54" prop to see 4000 rpm? Have you considered the Ellison EFS-2 TBI? It only needs 1psi but is typically run with 3-5psi. What speeds are you expecting at cruise and at what RPM?

Tom, I suppose my prop pitch will have to be up in the 60's somewhere. 3800 rpm is probably the most I'll want to go for. I originally thought about the Ellison, but there isn't one that's a perfect match for the 2.6 liter displacement. I talked to an A&P (sorry, I can't think of his name at the moment, but seems like he was from Michigan) who flew his 2.6 liter KR to Oshkosh last year. He had an Ellison and was not developing the kind of power he had hoped for. Ellison confessed that the EFS-2 wasn't really sized for that big an engine, but told them they were working on one that would be better suited for his application. I don't know if they've come out with it yet. The other thing that bothered me about the Ellison (other than price) was that tinkering with it was not easy (although probably not necessary either). I'm told that the orifices are very small and must be returned to the factory for resizing, although I've had good luck my Weber jet drills over the years. If the CIS injection starts to look too heavy or complicated, I may very well mount a sidedraft Weber 40 DCOE on top of the Type 4 (I have two of them downstairs).

For the inside cover, I used 0.8mm birch plywood on the sides and 2.5mm on the floor. The 0.8mm weighs next to nothing and is very easy to work with. - -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ------------------------------ Date: Wed, 01 Jul 1998 08:21:56 -0700 From: Micheal Mims Subject: Re: KR: smokin' VW's? <<>> In my quest for a lighter Lycoming I looked into the Ellison Fuel System for my engine. I wanted to remove the oil sump that Lycoming installed and make up another that does not include the intakes submerged in hot oil. This would have also made my engine about 8 inches shorter from top to bottom and 4 pounds lighter. Anyway I talked to the Ellison people about a unit for the 130hp range and once again they admitted to not having the perfect solution for that HP range. I also razzed them pretty hard about the carb costing $1500 and not being certified, I wanted to know why it cost so much? Needless to say I didnt make any friends at the Ellison skunkworks. I talked to three guys who have installed the Ellison on various Lycomings (235,320s) and all three removed them because of poor performance. The guy with the 235 said he lost almost 2 inches of MAP with the Ellison at full throttle. They sure work great on the smaller VWs but I guess they have a problem on the big iron. That's too bad because the two VWs in my hanger run GREAT with thier Ellisons. ------------------------------ Date: Wed, 1 Jul 1998 17:08:54 EDT From: KR2616TJ@aol.com Subject: KR: My little VW. Sorry, I don't have a big dog (just a 2180) so I guess I better stay on the porch :-)). I've had pictures of my "new" engine for a while but haven't posted them yet, but here they are http://www.geocities.com/CapeCanaveral/Hangar/7085/kr00005.htm Like I posted some time back, the case, push rod tubes and cylinders were painted using a oil based flat black cut with gasoline. It took probably 4 or 5 coats to properly stain them. I assure you, the color is there for good. Although my heads were new, I still installed new guides and re-lapped the valves. The only thing that really took any time at all in this whole process (beside flat out cleaning the fire out of everything) was cutting all eight push rods. I ended up using a metal lathe to precision cut each rod to match the first one cut. I suppose with the adjustment screw on the rockers arms, I didn't have to be so precise but what the heck it was fun using the lathe. You'll notice I added a little color, other than black, I thought I'd give it a little personality. Progress............The Smooth Prime on the bottoms of the wing stubs is sanded along with the bottoms of the horizontal stab. Using the ol' flip-o- matic (patent pending) we flipped it back over onto it's gear. I'll re-hang the engine and hook everything back up. Finished with all the instument panel wiring and plumbing, will concentrate on hooking everything firewall forward up. Man, this is getting scary.............it's getting there. I guess I'll have to fly it more sooner than later.

I don't know if they've come out with it yet.Mark, Check out http://www.ellison-fluid-systems.com/products/efs3a.htm to see the new EFS-3A unit for 85 to 140 hp engines. I think that I'll be going with this unit, since the turbocharged EA-81 will pull a lot more air than an 1800cc normally aspirated engine. I know Roger Enns uses the EFS-2 on his DDTS EA-81 engine, but the EFS-3A wasn't available then. The price for the unit is $825, which is $224 more than the EFS-2 and $604 less than the EFS-4. The Ellison throttle plate covers up a proportional amount of the spraybar at intermediate throttle settings. The Ellison spray bar itself also rotates with throttle movement, affecting the angle at which the spraybar's holes face the airstream. The spraybar is the width of the venturi, and releases fuel all along the spraybar, which I think is the key to the economical mixture settings. There's greater atomization of the fuel. Of course, if you need extra fuel to cool the engine, then you need it, and an economical mixture setting won't help. But with the liquid cooled auto engines, I can lean out the engine 300-400 rpm beyond peak RPM for the Lean Burn. I can't get over the price for that unit though. It's $750 for a completely rebuilt EA-81 engine block from CCR Inc. rebuilders. - -Tom ------------------------------ Date: Wed, 01 Jul 1998 15:19:35 -0700 From: Micheal Mims Subject: Re: KR: Ellison EFS-3A TBI unit Tom Andersen wrote:Mark, > Check out http://www.ellison-fluid-systems.com/products/efs3a.htm to see the new EFS-3A unit for 85 to 140 hp engines. >>> Heck that one might work on the Lycasaurus Rex.

I measured from the plans and it appears to be the 1.250 inch stuff. Is this right? I plan to pick some up on Friday before AS&S closes. Man they are sure proud of that stuff aint they? $40.00 per aileron! That's impressive! :o) Did you guys really flox anchor nuts to the backside of the 1/4 inch spruce spars? And it holds? I was thinking about riveting them to a 1 x 2 inch piece of thin aluminum sheet and floxing the aluminum to the spar. Anyone have thoughts on that? There was a question a while back as to what the motor mount beefup was from the KR2 to the KR2S plans and I mentioned that there were some plywood gussets added but I noticed today that the major improvement was the top motor mount rail was doubled! The KR2 plans show only one 5/8 thick cross member and the KR2S has two 5/8 cross members laminated together. - -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290,..
