In case you guys don't know on a turbo car this can be a major issue. With the additional boost pressure put on the back of the intake valve it can induce valve float and a loss of HP. It can also destroy you valvetrain. I have always known what valve float is but I have never seen it first hand. The video above does just that. We don't see it that much because on most turbo engines the boost pressure is keep low. Crank it up to 30psi and it can be a major problem.
