Hello Net Well Eduardo what you say is true. My prop had a resonance at 1300 and I was told by Ivo just to avoid that spot. I suspect that their may have been another at around 2500 RPM that was not as easy to detect due to prop blast. A most likely case is that the IVO is just not suited for the VW and that the resonance was the cause. My crank was tested round before installation. My IVO gave the resonance on both the old and the new engine.
