Spring Pressures. Solid roller lifter on a hyd roller cam.

I agree, you damage more with less and the kind that sneaks up.... Spring pads dug in, valves/seats hammered, bent pushrods...then bending/breaking valves.
With too much...all you do is destroy lobes,wheels, rockers...send metal everywhere. It's all bad to various degrees.
Imo That statment swings both ways.

You need the psi you state when the lobes are aggressive. If you take a slightly tweaked 'hyd roller grind' for a solid roller lifter..m then you need less psi. Generally speaking with your product..you're correct. Not debating the research your company has done and its findings with what it tested. It just really depends on the grind and you cant deny that .

No The statement does not swing both ways, I am not debating either I am just tell you facts. You do not destroy lobes from too much because solid roller cams have a Rc "Rockwell rating " rating above 63. Also no such thing as a slightly tweaked Hydraulic roller into a solid roller. Because Hydraulic rollers are measured at 0.005" for advertised and then at 0.050", where a solid advertised is at 0.020" and then at 0.050". If you run Crower lifters, cam, rockers, and springs It will never be bad to various degrees it will only be bad with too light ONLY. It does depend on the grind 100% I agree with that but separately from Hydraulic to solid roller. This is a subject that I talk alot about to people who go to Cam Place A-B break stuff and then come to us to make it work, and survive. We sponsor dragweek, rocky mountain, so on and so on real world torture tests. Once again by no means am I picking on you I just want all my mopar people to know the facts hence the reason why I am on this site.
