Are there any REAL experienced, "experts" here in this forum? ...Having done engines in real comp cars? this is pretty esoteric and technical stuff... but am very interested in talking to anybody... Roller bearing crankshafts are a bit of a side interest to us... 6 cyinder GP Honda motorcycles, M/V Agustas, these types of Porsches, Ferrari 312 Boxers with the 105MM rollers on the ends of the cranks,, Bugatti comp cars(i think it was an 8?, been a long time ago...) lets chat!
