I wonder if counter balancing and dynamic balancing of the complete
rotating assemblies would help this problem, i.e., counterbalanced crank,
balanced with rods, pistons, flywheel.
-----------------------
Counter balancing the crank removes high rpm vibration and the Forged
Steel Counter Balanced cranks have heaver webs to accommodate the thrown
weight increase.
-----------------------
I asked Bob Donalds about using different rods on the 2.1L to get around
some of the stretching problems in the lower end of the rod. If the rod
gives, and gets out of round because of the bolts or whatever, then I
would think a substitute would be in order. I have heard that with a
little work chevy rods could be used, but I'm not up on that hot rodding
stuff so don't have a clue.
------------------------
I've heard the same about switching rods but you don't want to go too far
into the nether lands.
------------------------
Anyway, I like my flat four, and don't intend to do a conversion. I would
rather modify what I have. It fits the hole, and is matched to the van.
Just a little more "oomph" would be nice, and I see no reason it
cannot be gotten, without everything going to hell in a hand basket. I
have a basket case engine I want to rebuild in 2003 and would like to
have some mods done before I start. It would be fun.
------------------------
Good Waser Boxer engines have run 180,000 miles with proper care. I think
the goal is a very good engine.
Check out Robert Lilly engine specs. More horsepower, runs stronger and
cooler.
I think its about an extra $1000.00 to build what is called a Full Lilly.
------------------------
By the way, when I go to the local private airport and listen to the guys
restoring a Cutis Wright or an old Biplane they got all kinds of war
stories to tell on engines ........... many have several crashes behind
them and don't seem to be very upset about it. Engine swaps in Taylor
Craft, Piper Cubs and Pitts are common and although they are supposed to
be FAA approved conversions I can assure you that many slip by because
the inspectors that do the annuals are buddies with the aircraft owners
or relatives.
