What I find comical about this is that people always seem to be surprised when a failure happens. I've worked in the engine building industry primary circle track. Let me tell you just because its "built" don't mean shit all it means is you prepared it the best you know how,with the best possible parts. We built sprint engines for 40k a pop and it wasn't if they blew it was when they blew. We recommended changing Carrillo's every 12 shows to prevent this from happening. Just for example. At the end of the day when failures happen both parties involved owner/ builder need to fix the problem and move on. We are abusing these things beyond belief don't be surprised people!!!
