RWS B-PSRU, 2.13 ratio If I recall correctly, takeoff RPM 6250, 26mp?, 5000 gets me about 145kts. but that is still pitched for takeoff.  Gear fairings all on now. The eng. is a Bruce T. custom, 1979 high comp. rotors, 1980 turbo housings with the larger oval exhaust, street porting ( ? think that is what is called ), 6 port Mazda intake modified to 4 port all precision matched ( hours & hours with a dremell ) smoothing, polishing, matching, housings to lower intake to mid intake to custom extended tubes reaching across top of eng. to starboard side into custom Dynamic chamber through slight bell-mouths & curved back-plate ( take advantage of rebounding pulses ) 3" Cadillac 4.6L Northstar eng. throttlebody ( very nice design double sealed ball bearing plate support throttle rod, NO vacuum leaks like you get with bushings ) 3" wire support scat to ram air standard Van's RV cowl inlet. That was going backwards. Sorry about that chief.   David

Hi Dave;
  I thought that you were using an IVO. I've got the 30"-90"×76"Magnum  and I never saw numbers like that. I knew I should have cut it down but I also knew that one day I would order new blades for it which I did about 5 weeks ago. So I'll be looking to sell the blades only and I figure they may be hard to sell without the hub but as they are still full length they have a better chance of being bought by someone looking for replacement blades.
  I'm looking forward to flying behind the deep pitch version.
  What reduction ratio are you running?

Todd

Do something everyday. That advice was given to me long ago when I originally began my project. One little job (or big job) everyday and eventually there will be nothing left to do but take It to the airport.
  Now this might sound oversimplified just like the whole "journey of a thousand miles" thing,
But what I believe is the key to this is that if you do something everyday then the details of the project are always kept in the forefront of your mind and when you have a hour or two to work on it you don't waste time trying to think about where you left off or what you are going to do next.
  For almost 12 years after I last flew my plane I was overwhelmed with other projects and responsibilities that I allowed to fill my brain to the point where when I would have a moment when I could consider working on the plane, I would find myself feeling overwhelmed and not knowing where to even start. So I didn't. Until finally I did. In the intervening years I did keep a task list on my phone and continued to lurk on the list so when various new ideas were brought up I would add them to the list for future consideration. The list grew to a very daunting size, to a point where it was discouraging to realize that I had been flying this machine and somehow there had grown this almost insurmountable list of tasks to accomplish before returning to the skies. When I finally got back into it, I started by just saying no to all the other jobs and favours that were consuming my time and space in the shop and then I spent an entire weekend not doing much more to the plane than familiarize myself with it and develop a mental state where I could recall the details of the many interrelated items that make this thing defy gravity. This is necessary but wasted time that could be avoided simply by doing something everyday then the details stay easily accessible in the forefront of my mind instead of buried in the dusty recesses of my mind. And now that very long list has only a small number of items without a checkmark beside them.
  When I started this project I was a relatively young man compared to all the old timers that seemed to dominate the airshows and getting an aviation medical was a simple formality. Now how the years have slipped by and I find myself facing next week's medical with apprehension. Although a little sore in the mornings from many previous injuries Im still very active and feel great, but I also realize that now that I've crossed that half century mark, there are a long list of hidden ailments that could be lurking unknown that would preclude the passing of a medical. And that would be truly heartbreaking to have wasted all these years not flying this plane.
     Then all I could do is ramble on, offering unsolicited advice on forums... ;)
  Lyn, over the the years you have given us much great advice based on your years of racing experience. Now let me give you some. Go out to your shop and lower that plane to the ground and do something on it. Today. And everyday.

All men dream, but not equally. Those who dream by night in the dusty recesses of their minds, wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act on their dreams with open eyes, to make them possible.

The micron rating of the last chance filter would be the same as in the car the injector came from or was used in. Find a filter with that micron rating (the one from the car) and cut it open. Lay out the paper or wire media and measure the square inches. Double that number and buy a filter(s) that have that numberof square inches of media and AN fitting capability.
 
 There is no application for hose barb fittings on an airplane or a race car. Change the filters at annual.
Sintered bronze elements can be plugged solid by a dose of water. I would not use them.  This is race car stuff. My BD-4 hangs from the ceiling unfinished.

Lynn,

    Do not think you are alone out there in "Project Unfinished Land"...........I am still plugging away with my Dyke Delta JD2 with the hope of flying before death............At age 76 I still look forward to working on it...........Would rather die building than in the recliner..............<:)
