Is there such thing as a good lifter?

I understand what your saying. The primary operational factor is RPM/bleed down time.
What I am saying is that the lifter will fill with oil more efficiently at 80psi than it will at 15 psi. Remember, it's bleeding down and filling up.
I would suspect it has an effect, if only a very small one.

If you look on their Q&A section, it also addresses that. It basically says they work the same with a standard volume or high volume/high pressure.

Course, I know all that's their marketing spill, but I've heard nothing but good things about them. I am also considering them for my new engine in Vixen, since they can also be used on solid lifter camshafts. The camshaft for that engine is even bigger than the [email protected] I have in the current engine.
