me and someone else debated the whole ceramic dust kill rb26 myth
i think it might have been me and r31nismod, or maybe someone else??
i dont think its ceramic dust that does the damage, i think due to either manifold design or how the twins are split, ie one turbo is cylinders 1,3,6 and the other is say 2,4,5
when one of the wheels lets go it basically causes excessive backpressure or some form of exhaust backlog and causes excessive detonation
i just dont see the culprit being ceramic dust
