it does no f**king damage!
listen to all the people that have actually done it, rather than those who think they know everything.
if your running 14 psi on a stock turbo with no bov, EXPECT the kent to blow a blade sooner or later!
i for one, ran 14 psi, on my hi flow vg30 for yonks, not a prob.
there are plenty of others out there who have the some opinion, joel for one.
f**k me.
