Re: Thoughts on my new motor build
And I can clearly see that Marv had one heck of an issue with the Hyper pistons, but what am I missing that makes them so bad in your eyes?
The content of silicone above the soluble 12% makes them brittle . I'll try to explain it . Hypers are cast pistons . Think like Iced tea . You can add sugar to the iced tea and it will mix till it is saturated with sugar , at some point the excess sugar just goes to the bottom of the glass . For a piston that is around 12% silicone . Hypers are above 12% , say 16% They are ok for stock rebuilds to tighten up clearences to help with blowby and piston noise , but i along with Marv have had bad experiences with them and will never use them in a performance application again . This is my opinion and i tried to explain it the best i could .
