Piston | 1: | 2: | 3: | 4: | 5: | 6: | 7: | 8: |
Old | 1374 g | 1370 g | 1379 g | 1376 g | 1377 g | 1370 g | 1374 g | 1373 g |
New | 1377 g | 1375 g | 1381 g | 1378 g | 1378 g | 1372 g | 1378 g | 1375 g |
Difference | 3 g | 5 g | 2 g | 2 g | 1 g | 2 g | 4 g | 2 g |
Wow, only a few gram difference in each piston. I think I'll call a professional and ask if that makes any difference. Most likely not as, according what I've read, they didn't even balance the moving parts in the factory and my engine would not see high RPMs.
And just in case someone is interested, I also weighted just the new Sealed Power hypereutectic pistons and pins. They were between 750 and 753 grams. And for the new piston rings:
1st pressure ring | 2nd pressure ring | Oil ring |
17 g | 20 g | 22 g |
