Experience With "Balanced Cams?"

I got it, just trying to lighten things up.

Who's he working for?
Yates, RCR, Hendrick, Penske, Evernham, Gibbs, DEI ?????

Did you get a letter from the Pope yet?
What's his position on balanced cams??
You really are funny.

I'm really sorry that real world results don't fit your modeling fantasy world. Maybe you should have studied harder.

Mike what real evidence have you presented from the real world?

If cam balancing works, I want to know it.

All I have seen so far is unsupported theory and claims. So far, every claim that you have made that I looked into did not match your claims at all.

The harmonics issue isn't modeling, the natural frequency of an object is measurable and that of a camshaft is nothing even close to the speed of a cam.

You have not answered the critical question about the location and couple of the supposed harmonic after three requests. I can only assume this is because you don't know. If you don't know this, you don't know what is happening.

Virtually all camshafts are designed utilizing vibration/harmonic principles.

Anyone wishing to argue about the above please contact any engineering professor I ever had!

Please remember one thing:

Yes, is anyone disputing that?

The key question is at what frequency.

can you tell me what 66Hz force can do to a body with a natural frequency of 300 Hz? This is Engineering 101 stuff.

Mike, you simply do not know what you are talking about when it comes to physics.

Thanks for giving me your opinion.
I'll note it, and file it with all your other opinions.
This was your opinion 17 pages ago.

But balancing the cam alone is pointless, you would have to balance the entire valvtrain dynamically to know that you were changing anything let alone in the right direction.

You made up your mind long before I ever responded to this thread.

Mike, I would be happy to know that balancing cams improves anything, so far you haven't presented any reason to beleive that.

I challenge your claims because they don't match any information I have seen in any book or papers on cams or even basic physics. These books are written by people with far more experience, knowledge, and access to data than either of us.

You have been unable to explain or support your claims and when you have tried you have made statements that are easily checked that are easily proven to be incorrect.

Don't be surprised that when you make claims that contradict basic physics that you will be challenged.

If you actually wanted to learn, you would have read the artical in Circle Track. You would have looked at the spin-tron results. You would have asked for the name of one of my customers to ask them what they've seen. You would of asked for info from the people on this forum that stated they've balanced their cams.

You had your opinion on page 1, and stuck by it.
You've challenged nothing but my patients.
You've proven nothing, but your lack of connections.

Good luck with what ever you do.
Real World results don't lie.
