Mitsubishi 6G74 crankshaft, checking balance factor (15).

I've made more bobweights and spun it up. The ideal bobweight for a stock crank comes in at about 950g. Any more or any less and the imbalance increases.
This figure is a different percentage given that the same crank is used with both DOHC and SOHC as well as GDI engines as there's a difference in piston weight of 70g.
For a SOHC it comes in at all of rotating and approx 48 % of reciprocating weight while for the DOHC it comes in at all of the rotating and approx 47% reciprocating. For the GDI the figure is about 45%. This compares to the 6G72 crank at somewhere between 44% and 45% reciprocating weight.
I've got several of these cranks . It seems like they've drilled the balancing holes in all of them the same. Same position, same diameter, same depth. Doesn't seem to be very accurate. Same crank, same weight, different application gives a different balance factor.
The figures used are piston SOHC 372.6g, DOHC 398.9g,GDI 473.1g, rings 30g, pin 134.9g, rod only 445.2g, nuts and bolts 82.7g, cap 218g, bearings 31.7g, circlips 1.9 g, oil 3g, small end 185g, big end 595.6g, total reciprocating 724.4g for SOHC and 750.7g for DOHC,794.8 for GDI, total rotating weight 595.6g.
What's next? Repeat for my stroker 6G74 crank.
