Giving a talk on cam selection, and need your input
I'll be giving a talk on cam selection, and need some help.
What questions need to be covered?
What common mistakes do people make?
What would you like to learn about cam selection?

Re: Giving a talk on cam selection, and need your input
How do you select a cam based on head flow numbers?

Re: Giving a talk on cam selection, and need your input
Do you know the level of understanding of your audience? That would drive the level and complexity of the questions, based on where they 'should' be on camshaft knowledge. For example is this for - novices, intermediates, experts, professionals? It may span more than one, but unlikely all. This would then help build out how low or high the conversation will start and then finish.

Do you have hot cams for Tesla or Chevy Volt?
Sorry man, I couldn't help. I wish I was in the audience of this Cam Talk by Mike. Any chances to be filmed and go to YouTube?

Re: Giving a talk on cam selection, and need your input
Explain why different cams with very similar lift and duration numbers need different springs, seat pressure, spring rate, etc. What advantage or disadvantage is found comparing cams which require more or less spring pressure or spring rate. Describe the effect on HP and Torque of cams which require more or less pressure/rate.

The way people rise above the level of novice is through exposure to expert knowledge and to engage in conversation with people deemed to be expert.Curtis Mc wrote: ↑Thu Aug 09, 2018 2:08 pm Do you know the level of understanding of your audience?

This will be during The Race Engine Challenge competition in October. So I'm assuming everyone will be above novice.

I don't, actually.
I use the flow numbers to calculate the "Effective CSA" of the ports.

You might talk a bit about the differences between, "balls-out", high rpm race cams, and, wide power and torque, "street", cams.

Re: Giving a talk on cam selection, and need your input
Just spitballin’ here mike , but in my experiance, I would start with the rationale (what you see as important, your approach) for how you pick cams. You need to be yourself!
Make a list of what you think the important points of picking cams are and I would bet the common mistakes you want to cover will become appearant fast.
Sorry that you already know all of this -but the point I guess that I am trying to make is that if this talk is a face to face class type of situation-be authentic by being yourself and giving your honest assessments. The students will want that or they will just be thinking “same Thing as everywhere else” (at least that is how it goes with my HS industrial technology students) - hopefully the people you are talking to won’t take as much convincing as the teenagers lol-

Re: Giving a talk on cam selection, and need your input
How do you use the Effective CSA of a port when selecting a cam?
Joe Facciano
Re: Giving a talk on cam selection, and need your input
How will higher lift affect where the engine makes power?(or does it?) Everything else left the same.It may give gains in output but does it affect where the engine previously made hp. As does duration? And if heads peak flow at say .700 is there any gains designing cam for .750-.800 lift? I wouldn't mind knowing the answers to those questions Mike.
Re: Giving a talk on cam selection, and need your input
Factors to consider when choosing a cam for an overhead cam application versus a cam-in-block application. Finger-follower vs bucket action.
