What kind of torque was your engine producing with those mods?
Connecting rods in BAM engine should be quite fool proof up to 300lb/ft.
These incidents makes me thinking limiting the torque of my Ibiza MK4 Cupra, which has even weaker rods than the ones used in BAM engine
had a few rr printouts with the 300 lb/ft mark, im uprating engine so this dont happen again
