Your a pro at staying out of it as you have shown here... My field of expertise is exposing those who claim to be experts!Warp Speed wrote: ↑Mon Apr 10, 2023 9:41 amI'm trying to stay out of it and watch the dumpster fire these always turn into. You'll make sure of that!

I guess that you are referring to the cam design software I wrote.
So what your saying is that what you have to offer for the average racer is useless and maybe what DV resents could be more beneficial to them?SchmidtMotorWorks wrote: ↑Mon Apr 10, 2023 10:04 amI guess that you are referring to the cam design software I wrote.
It enables a designer to define valve motion with detailed control of the shape of the acceleration curve to include jerk and snap.
It is not involved with determining lift and duration specs or mechanical analysis.
For those goals working at a professional level, one would also need:
1D simulation
Dynamic Motion Simulation
CFD would be helpful
The average racer is not involved with cam design.
I'm curious, what would you call making a video titled about Pro-Stock, that was nothing more than the most basic cam stuff that one could find in the 1950's?
The video that I responded to was titled "Hyper advanced ProStock-plus, cam tech", if it were actually about what the title BS says then it is not for the average person.digger wrote: ↑Mon Apr 10, 2023 11:58 pm the average person doesn't care about all these curves its the cam grinders problem. I think a discussion on events is more useful.
Given the valve events are all coupled there is at least some merit in looking at centrelines but without a specific criterion its impossible to have a clear winner that cam A is better than cam B as there isn't a single answer as to what is the best cam.
Its fairly straight forward to determine which is more important for a given application as you start with optimum cam and change one variable at a time and look at sensitivity of the output. You could vary a single valve event or only a single lobe centreline (which involves 2 events and usually also the lobe area and lift change at same time in practical terms)
If you were use Engmod4t to iterate to a optimum cam what would be the method to determine start point and path in changing one or variables to arrive at the optimum solution as fast as possible?
