Yeah, the issue with this conversation is the possible parasitic loss cant be measured , cant be seen. No way to prove it either way. I just look at it from a mechanical common sense view point. I remember when I build my motor and the pan was still off, I noticed how bad the rods were layed over when the piston was at BDC. I would sure think there would be alot of friction with the piston side loaded like that . Just think how bad that would be at 7000rpm or even 6000rpm. sure seems like that would create alot of friction dragging things down a bit. Either way, it cant be a good thing.
