I would like to see a video specifically on the rpm limits of a hydraulic lifter and the variables that cause the rpm limits to be lower than a solid lifter. Also, the reasonable maximum sustained rpm for a hydraulic lifter in a street/race performance engine. We know hydraulic lifters are avoided in max-effort racing engines but where is the line where a hydraulic lifter can safely go up to and at what point must a solid lifter be used.
The limits have way more to do with the smaller wheel and axle sized used in most hydraulic lifters than the hydraulic lash adjuster. It's very likely a larger lifter for racing engines that was converted to hydraulic would have the same limits RPM--wise.
So, a hydraulic roller lifter for a street small block Chevy can sustain the same rpm as a solid roller if the same retrofit linkbar type lifter is used with the same roller diameter? Are you saying that a flat lifter can sustain more rpm than the standard roller lifters for the small block Chevy?
In a lot of engines the head actually expands away from the block especially with iron blocks and aluminium heads. Setting the base lobe gap on some European engines where the shim is under the bucket (such a stupid idea) in a cam box that grows or expands away from the engine when hot can be a very trying experience
I was literally contemplating this subject earlier today, awesome that you made a video
Glad you found it helpful!

Wow, great information!
Thanks!
Good Job Ben

Great video!
Glad you enjoyed it
DLC solid roller for me 🏁🏁🏁
great choice
What about short travel hydraulic lifters?
that poor endmill 🙂
Haha yeah they take a beating
