I never said the boost was brief. More likely it was a sustained peak pressure and this occurred many times on 0-60 runs. It did not help that the vacuum line from the manifold to the EZ69 and the manifold to the waste gate were switched. And there was a 1.1 bar spring in the waste gate. These conditions were bad but the over boost sensor would have prevented the over boost condition that ultimately broke the rings, that was the point of my post.

I showed the rings to several engine builders, with universal consensus, over boost.
