I'm in Australia, and we use per second, not a second 😆 😂 😅. On a more serious note, in the early 70's, Ford published flow figures for the Cleveland cylinder heads, and the intake system, less carburettor. The flow figures we given at 5" Hg, or 61" H2O. They also included some of their competitors heads in the head flow charts for comparison. What is interesting is that at low lift, there isn't a great deal of difference, but at high lift the difference is significant, and it just keeps increasing. I have a friend who has worked in Fords engine development divisions, and apparently, 5"Hg is their standard test pressure. Low test pressures hide high flow rate issues
All this theory ,when is some going to shrink a person down too 1:24 scale & put them in a motor ,with Miniature equipment to see whats going on lol ,because theory has a lot of empty holes lol
I thought that smoother taper valves work on strait in ports and nailhead valves work better on valves where the port is at a steeper angle..
Mad Motor Skills! 👍😎🤜💥
Where can we find the full videos? I thought George stopped doing the Lives... lmk miss talkin George!

yes the piston goes up twice per rpm but we only count when the plug fires, so the valve is opening and closing 100 times per second at 6000 rpm
No the cam timing is half speed of rpm
But isn’t rpm based on the plug firing?
It's Revolutions per minute, not ignition events per minute
@@FabRightMike ok fine
What?!? You’re confusing RPM’s vs cycles....2 rpm’s/cycle
lol
