All getting a bit ott now. Tony could have posted a picture of the pistons and perhaps put this whole thing to bed by now. After all, he's had time to post up igntion figures agaisnt boost and rpm, which takes longer to type than take a photo.
And Danny - Stu has answered about igntion figures and in his opinion they were a tad on the high side.
Seems to me, no one is right and no one is wrong, as no one can actually prove why the engine let go!
May as well leave it at that
