Ok I am getting fed up of this now !
Michel, you state clearly that you restrict the boost that your cars are mapped to, in My case i asked Dan to give me a 'safe map' this was agreed at 1.2 bar with or without NOS and 1.5 bar without, I was not present like yourself at the session, Dan clearly states in his post the car failed at 1.75bar, how is that a 'safe map' I dont know thats why I asked the forum
I did not loose a tyre here or break a spark plug, I lost the whole bloody engine including a just rebuild head.
I wanted some answers and was told this stuff just happens sometimes, I dont feel that is a good enough answer, if it let go at 1.5 bar fine thats my problem but it did not, it let go at .25 bar above what I asked for, and was told that mapping above is normal to get a consistent map, well I would have expected any mapper to warn me of that before hand because MANY people in the know have told me 1.75bar on a standard engine is asking for trouble
Ok rant over
