So you basically didn't answered his question at all by saying only "3.5 bore pistons" without any detail nor job number.
Questions are good, answers are better but well... it's not the first time someone asks about details from your projects without having any answers, guess we don't have the same defintion of a "community" as you call it in another topic :]
Actually I think the only useful information you posted here was the single mass Saab flywheel stuff, compared to this I'm not sure I'm as useless at this...
PS : I don't doubt any of your stuff or numbers or projects as vocky saw these and I trust him without any doubt, you just can't tell you're sharing anything useful to the community about these...
