Lubrecon,
I have a genuine question regarding synthetics and roller lifters.
I race dirt Late Models and we run roller cams with .700+ lift and very high spring pressure turning 8-9000 rpm. The trend recently has been to run synthetics since is seems to increase HP by about 2%. Around the same time we switched to synthetics, engine builders began noticing unusual wear on the cam lobe; the surface of the cam appears to flake off. The theory given is that, because the
oil is so slippery the lifter is not able to roll, but instead slides, causing the wear. The only constant among many engine builders seems to be the
oil. Have you heard of this? Thoughts?
Thanks,
Scott
