I play about with solidworks a lot and was wondering what you thought about my approach to the VW W12 and whether you lot have tried this. I was playing about with the stroke to bore ratio and found that pistons interfiered in the 15 degree vee angle banks once it got towards square.
AS you probably know this idea by VW saves space but makes cooling difficult. The conrods have to be thin as well. The actual W12 crankshaft has splayed cranpins but i balanced my crank this way and achieved 78% reciprocating balance at 5800rpm.
