weight of j&e turbo piston

[1320n10]

Looking for the weight of a 4" bore j&e turbo piston to compare with the weight of the pistons in the 9.0 to one asa motor

My 9.5:1 were 508 grams with a 4.005 bore

Thanks i will check the weight this weekend and see how they compare. The dioamond pistons look pretty tuff but the top ring is pretty close to the top.

Just for another comparison I run venolias in a bore of 4.055 and the slugs weigh in @ 433 grams. They do gain a little weight because we went with the pin butttons. All in all a pretty light set up.

Bare piston is 474.

piston weight

The longer the rod the shorter the compression distance.The shorter the compression distance the shorter the piston itself which equals a lighter piston.So rod length and stroke greatly effects piston weight.If your comparing weight you may want to also know compression distance.
Piston pins differ in weight as well.A tapered wall pin would weigh less than a solid wall pin.
