I can remember to sbd. ( I think it was Adie) who has blown his engine on his way to JAE2006,
holes in the block due to broken conrods had been the result of 0.9bar of boost.
He has it rebuilt with my custom forged internals and has blown it a second time due to wrong head bolts.
After 2 years I think he was finally able to show us a 380-400BHP dynograph when his car was set up completely.
And doing 50 dyno pulls doesn't say anything, you can do 1000 pulls and it will be fine,
since on the dyno there are far not such straining conditions as on the road, during to weight of car, steep roads,
air resistance and other things.
But if it's fine although then we all are happy to be wrong thinking this engine can't take more than 0,7bar of boost.
So let's put that monster on the Dragstrip, doing 1/4 miles and other races on the track and we will see.
