I'm sure EVERYBODY who is now running a 160 hp. O-320 will
be VERY interested in getting more info !! ======
For those who missed it, we have reported cases of THREE Warp-
Drive prop blades CRACKED by the harmonic vibrations from the 160 hp. !!
There have been NO reports of problems with the 150 hp. versions -
something to do with the stronger power pulses of the 160's ....
If you do not add the flywheel/balancer, PLEASE check your
blade ROOTS regularly - the cracks might appear in the composite,
OR the metal shaft !!!
Take care !!!

---------*Hi Bob,
I did a little more research on the Harmonic balancer that we talked
about. I got ahold of Rick Engvall who is running a o-320 160 hp. with a warp
drive and he cracked his prop in the first 10 hrs of use. After alot of
research on his part he talked to a company that runs an ad in sport
aviation. His name is Mark Landoll and the phone is 405-392-3847. It came
from drag racing where they run it to counteract the torque in the
crankshaft,or somthing like that. He is very free with his info according to
Rick, and Rick says his 0-320 now runs like silk. Cost ? Well, it weighs
12lbs and bolts to the starter ring. Price? 375.00 US Hope that was a help.
