Just got the 3mm O.S. piston kit from Cruisinimage and considering those pins from Mike's that are billed as lighter. Looking to keep balance close to original. Any thoughts?
Decided to use Wiseco internally tapered pins. They are billed as 60g weight vs 91.7 for the Cruisinimage pin part as measured. Pistons @ 280.7 and 281.1g. I thought that to be very consistent to each other being only 0.4g variance. From postings by others on here it looks like stock 447 std piston with pin comes in at 357g and my piston with Wiseco pin at 341g not counting clips or rings on either. .Isn't lighter by about 17g EACH a lot better than nearly that same amount heavier? Less reciprocating mass by more than an ounce should mean a lot at revs.....
...are 447 pins the same diameter as 533? I have a 533 crank/rods for my XS project.
Yeah, I saw that, sorry. Could have been more clear. I know the weight balancing is done from the inside. Just a general question between the two mods.The dimpling is not the weight balancing....(could be considered/used for weight loss)......That is done from inside the piston
