Re: Model A cam ground to "B" profile
Be sure you know what B grind you have. Is it an OEM original grind or an after market
re-grind? It makes a difference. Original's were designed and made with a whole different math program. Mixing grinds and lifter face diameters is NOT a good plan. Another thing to remember, original OEM lifters were faced FLAT. Most modern ones are tapered. |

Re: Model A cam ground to "B" profile
I think that Formula 1 racing cars are now using pneumatic operated valves that are controlled by a computer. That means the timing is variable and that the valves lift and seat quickly. The timing can be tweaked while the engine is on the dyno to get the most torque at each engine speed. And even tweaked for each race course. The race course in simulated in a computer.
I wonder what AI could do?

variable cam timing has also been around for some time, is in many production cars today. I read years ago about electromagnetic valve actuation experiments. Not sure it has made it to the track yet. Personally I like the older desmodronic valve setup. J

Gives you the "low end grunt" of one valve timing profile AND the higher RPM power of a different profile in same engine. System is called VVT Variable Valve Timing. Introduced in 1995. Last edited by Benson; 02-23-2024 at 11:02 AM. |

If you have never seen a cam get ground kinda interesting video not model A but it shows the machine and how it grinds the lobes to shape and there placement relative to each other |
