I think I
experienced a small amount of turbo surge during my last flight. It was only
evident when MAP was between ~ 0 & 0.5 psi boost. A small change
in throttle position in either direction would eliminate it. It sounded
& acted almost identical to the way that the engine would previously act
when positioned precisely at the injector staging point. But my staging point is
at ~ 18"Hg and I have that well tuned now so as not to cause a problem.
So my question is aimed at those with greater knowledge and
experience in this area. What exactly does turbo surge feel like? What are the
symptoms? Is it likely that what I was experiencing was just tuning related? I
do have the TurboSmart electronic boost controller, but since I hadn't played
with it since last year, I didn't want to make any adjustments without taking
another look at the instruction book again, but I doubt that it was
related.
