I love my paint scale.
Goofing around in the garage a little last night, I did some comparisons between factory bits and what's going in the Challenger's 340. The piston/pin assemblies are 220g lighter
each, which is a total difference of 1,760g. The BME connecting rods are significantly lighter than OE--300g
each. That's another 2,400g, for a total of 4,160g or 4.16kg.
If you're reading while this sitting in a country with a flag on the moon, that means I'll have removed around
9.2 pounds from the rotating/reciprocating weight attached to the crankshaft. Roughly estimated, they'll have to remove
another 6 pounds from the crankshaft just to get it in balance. A 340 is a quick-revving engine in the first place; I can't
wait to see how quickly one will rev with ~15 less pounds swinging around inside it.
