Hi Chris,
I lost a rear iron from detonation when I first
started experimenting with a turbo 13b. The main reason was a lean
mixture.
The formula for detonation is: high intake
manifold pressure, high intake air temperature and a lean
mixture.
I would never go over 30" intake manifold pressure
before I know for sure that the mixture is NOT lean over the full spectrum --
from idle to full power. One way is to watch the manifold pressure as
you open the throttle and limit it to 30". Do not open to full throttle
until you know you do not have a lean mixture spot.
If this problem occur on one rotor only I would
check the secondary fuel injectors delivery rate. If one deliver more
fuel than the other, one rotor will run leaner. Then, you probably cannot
tell by the o2 sensor readings.

Chris,
Well, at least this will be an inexpensive repair, but any idea what
caused the springs to flatten out like that?
