Look who's talking!
Anyway, the base engine on my car has done some 20 000 miles with different levels of power. First running 250 bhp and gradually improving to the current 300+ tune. It has also done numerous top speed events and track days also in current spec. Does it proof anything? It's hard to know since every engine is a unique item and everyone drives and tunes them diffrently.
