Like the title says.
I will be rebuilding my 4.6 soon. The point of the rebuild is to make more power. I talked to Lito and he thinks for my goal of 550 hp (or somewhere close), I might need to be as high as 14 pounds of boost. The car has a Roush supercharger and is drag raced and street driven. I will likely be using Manley pistons. They offer 3 ring packages that I know of. I am considering one of two. The difference is steel top ring or Plasma Moly top ring. Manley says I need the steel at 15 lbs of boost. I am thinking I need the steel ring package due to the abuse.
What ring material are you using and why?
If it is steel, do they wear the bore any faster?
If it is moly, do they hold up to the abuse?
Thanks in advance.
