Well, to say cars have had engine failures soley due to antilag is probably a bit misleading, but they certainly go hand in hand
from the top of my head, joesac, protorob, wrp10 adams car, ja50n, sti tuned, wrx-sti brad, clints old car etc all have a: used antilag and b: needed a rebuild. sure if it doesnt kill it straight away but it is detrimental to the life of the engine
