Length of S65's connecting rods?

[Richbot]

Long shot here...Anybody have this dimension? Anybody have a stock connecting rod laying around you could measure? This dimension goes from the centerline of the wrist pin to the centerline of the big end.

EDIT: Nevermind, looks like there are aftermarket rods out there in stock dimensions. 140.72mm is apparently the dimension, with a 75.2mm stroke that gives a rod/stroke ratio of 1.87:1, which is pretty damn high. For reference, the Honda S2000's 9,000 rpm, 118.5hp/l 2.0l F20C was around 1.82:1. This ratio bears directly on piston speed and bending forces placed on the rod, another member's comment about a good naturally aspirated setup as an alternative to supercharging got me thinking about what could be possible with this engine and it seems 9,000rpm isn't out of the question with this bottom end assembly from a piston speed standpoint when it comes to longevity. Just a couple ideas banging around in my head, with the power peaking so high on this engine 500 extra rpm would be a really nice improvement in acceleration potential even with no other changes. The fact that BMW didn't build it that way suggests that they ran into diminishing returns for materials choices and/or weight savings in the valvetrain and rotating/reciprocating parts and didn't want the damn thing flying apart. They did the same thing with the limiter on the S54 and S85. People are already achieving 110hp/l on this engine with bolt-ons, imagine being able to shift in the right place (without going boom, that is)

Either way, the flexibility they've managed to wring from such an undersquare low displacement engine is really amazing. Just needs mo' revs and some nice big cams for the topend. Whatever, nothing to see here, move along.
