Ok, so the spring doesn't actually spin like that sped up 150x.

That engine is speced just right! Literally compressed to perfection just before coil bind. Using every cm of power u can!

Oh yeah? So why are the other valve springs not moving in the background? Seems like bullsh*t to me. Just a slow vid of a single valve going up and down in slow motion. Doubt it’s 8k rpm.

Do valve springs need to be replaced after a while? What are the symptoms? Thanks!

Consider that ANY piston (not rotary) engine at the slow 600 RPM's - EVERY piston of that engine - changes Direction TWENTY times - in ONE second! 600 / 60 seconds = 10 times to the TOP - but you also have 10 times at the BOTTOM of the stroke. Here - we look at a valve spring. But the Piston - EVERY piston of this Engine - is moving at 141.66666 strokes per SECOND. And each piston is changing direction (going down; going up) 283.33333 times in ONE second. This why piston engines do not last very long - at 8500 rpm's. They self destruct.

holy cow. didn't know about the wobble of the spring at high RPM. this video is an advertisement for the desmodromic valve system.

No valve float. good job. The most I've been able to get from a naturally aspirated stock V8 4 barrel is 6000rpms. I ported the cast heads, also ported an aluminum intake manifold and swapped a few carburetors to achieve 6000rpms in a motorhome 😂😂😂😂😂

Is this 8500 engine / crankshaft RPM, as most of us would understand it, or is this cam RPM?

@stevepulse48937 ай бұрын
Extremely high rpm engines don't use this setup. Instead they use pneumatic valve trains making the weight of the springs & retainers irrelevant. 4 valve systems are also superior to 2 valve systems in this manner, 4 valves = smaller components= less weight. Less valve lift required with equal or more port velocity.
