engine blow outs and why ?

[0630154]

why do cossy powered engines blow up more than rs turboed engines ?
i have never realy heard much of the rs turbo cars engines blowing up and they can be boosted up .

but cosworth powered cars let go a lot more any reasons , yes more power but any other reasons ? more bhp ?
just a small thought ?

to much boost kills um and shit mapping

An engine's an engine . Tune it up too double the standard power with a big turbo on it etc etc and it needs good parts and set up (timing , fueling etc) at all time . The slightest thing will kill it , even stale old petrol or a worn out fuel pump on full boost could be terminal . Fooook me , even a red hot summers day will see a few go bang if they've be set up by Micky Mouse !!!!!!
