The VVT mechanicals appear to be rather stout. I am just not happy with it's efficiencies. IMO the back (drive) pressure to boost ration is poor.
Depending on what RPM you are running at, I could see getting 40 PSI boost at around 200K RPM shaft speed. At higher revs, I don't think the VVT breaths well enough to keep up. But I really don't know for sure.
IF the compressor stalls at anywhere near those speeds, parts will fly.
