Well, exciting to me at least! While going through the net I happened upon a great bearing alloy, C72700 and/or C72900. (Spinodal bronze aka Nicomet and...
Hello Jim, You too - thanks for asking that question - I've been mulling over that very one ever since seeing the photo. During my years of dabbling in motor...
Jim, The master rod in the photo looks like its from a B series R-2800 This engine had the master rods in cylinder #s 8 & 13 The C series master rods were in #...
A true story. We have Fletcher top dressers (Crop Dusters) in NZ and they used a IO- 720 lyc. with eight cylinders, and are 400 HP. (off topic I know but they...
... Jim, I should have read the original message before hitting the keys. Peter states that it is a 985 assy I'm not sure which position the master rod was in...
Glad we figured out the bent master rod mystery. Never would have guessed that someone would cause it to happen that way. Maybe there should have been a cash...
I haven't been to the HCI web site yet, and it seems the link is gone/expired or the whole web site is down. Anyone else experience the same? Jan Servaites...
My name is Mark. I live in Georgia. Looking for anyone in the southeastern United States that is currently building and engine. I would like to see one under...
Hi Jan, The site was down for a few days, but I think we're back up and running. Try refreshing your browser and see if that works. If not, could you please ...
It's there now. Thanks. I want to order a set of plans to review them to see what's involved. I was actually thinking about using VW parts in building a radial...
Hi Mark, I live in Central FL and am building a derivative of the HCI design. (Some people can't leave things alone) It would be nice to know where everyone is...
Thanks Jim, I plan to come to Sun-N-Fun , but am very excited about this engine. I may see about coming to see your project, if you are willing. I live just...
The fuel puddles because of the runner configuration and the turns. The usual solution in a radial is a diffuser turning at crank speed that the guys at HCI ...
... Yes, at my first glance at the problem, it appeared to me that the length of the intake runners are pretty long and the diameter is too big. I looks to me...
Here's what I know of the problem with fuel pooling in the runners and what fixes HCI tried before trying fuel injection... The problem of fuel pooling came to...
Jim, I was thinking about the problems associated with the asymmetry of the radial's piston timing (due to the articulated rod design) and the symmetry of the...
The Wright brothers site is neat! I really don't think that acheiving precise symmetry is necessary for what we are doing. Almost everything I've read says...

It wasn't anything, but converting a Corvair 6cyl to an opposed twin. It didn't seem too exciting. -- Jan Servaites (Dayton OH - The Birthplace of Aviation) ...
Yesterday I picked up a couple of Audi cars. (5 cylinder engines). One a turbo, has the igition electronics combined with the Fuel injection system. The...

From a fluid mechanics point of view: Perhaps the dwell time of the air/fuel mixture is too long allowing the fuel droplets to settle out before the charge...

Although a carbureted system would do initially anyone considering flying behind one of these engines would be much better off with fuel injection. (MPFI not...
... Yep, and not that hard to do. A simple digital control system and a fist full of injectors will do. You still need the tubes and a throttle plate though....
Howdy- I talked at length with Jack several years ago about using the SDS MPFI system. He thought that was a good approach to the problems with carbs and long...
