What is it about the 4032 alloy that makes it work over the 2618. Is it the expansion rates of the material?

In detail, what differentiates FRM sleeves from Iron. other than you can run a forged 2618 alloy piston on a iron sleeve, and I do realize it is a completely different setup but I just want to know more about it

Is the FRM coating strong? In other words if we had a piston that would work in an h22 with out skirt to sleeve contact would the sleeve be able to handle say 550-600 crank hp.

What is it about the pc9/ anti friction dry coating that makes it work at break in? what changes after break-in that makes them all of the sudden work

The frm coating is only .020mm thick so what material is in the sleeve outside of the frm?


I just ask these questions because I want to know more about my motor. I personaly will sleeve my block because 1k$ does'nt seem like to much to me to have peace of mind when I'm doing a 5th gear pull at 25psi.

 

Sleeve it and do a search.
