    Well running even a Low Boost wheel at 9000 rpms is high boost compared to stock...

    Maybe it’s because I’ve never taken the housing off that I don’t understand how it’s walking. There are two halves that make up the SC housing. The outer part has to be drilled, taped and screwed so it doesn’t walk back? What is it being secured to when tapped if it’s only going through the outer half? Some Pics would be helpful. Thank you

    The front half of the sc housing is two parts that are pressed together. It is hard to tell but where the air enters the sc os where the two parts are pressed together the screw keeps them from seperating, over time they tend to seperate from enging heat alowing the inside front half to move backwards touching the sc wheel.

    Thank you and great timing.

    While doing tunnel reinforcement and my engine is pulled, I will make the modification.

    As always, great information!

    Thanks.

    Ok. That makes more sense. Thank you for the clarification. Is it easy to take the two halves apart?

I have only seen this on higher boost applications so far. Currently I have not seen any stock SC covers do this. Just want to give everybody a heads up on this. I'm not saying there is a mass epidemic of this. As of today, there have been only a few that I've heard about. I Don't want to cause a panic out there, but if you plan on pushing high boost with one of the non pinned covers, you might want to think about drill, tap & install a screw to pin the volute in place.

    Hope this helps!

    This Apply to the 2017 SVHO still in the GP's?
