Has anyone done this on any cars? I realize there is no downside but I am looking for proven results before I write the check.
I thought you were the best? I am asking because I don't know the answer, not because I doubt John ability. I would just like to hear from people here who have been in my boat... Would you balance the cams?All the money you've spent and your going to question this mod by one of the best in this business?

As a guy that balances stuff all the time, I have never heard of balancing cams. I have however balanced cam gears in the past. I'll have to spin a cam up and see what is what with one. I just wonder how they do it. How do you take weight off or how do you add weight. Being so close to center line, I would think its not going to make much difference.
Lightening holes would be my guess
Do factory high revving engines come with balanced camshafts?
the only article I have found is this http://www.circletrack.com/enginetech/ctrp_0603_cam_shaft_balancing/index.html
It looks like a few race teams have been doing it for a while but the results are very hush hush. John claims it helps hold his big power motors together and I believe him. I just think he is spinning the bajesus out of those motors and I don’t plan on going past 8k rpm... unless the power curve looks like a ramp and A/F and spark all look solid, then I might MIGHT go to 8.5k. It still looks like there are no measurable benefits until you hit 10k rpm. However, for $600, I will probably just write the damn check and do it anyway. It usually pays to listen to people who know more than me. i.e.: Fish has me doing a MoTeC with knock sensor and a nutty fuel system. As long as it hold together, I’ll be happy. I have won more than one race because the other guy car didn’t hold together.

True, I read in that article that there are several ways to go about harmonic damping in the valve train, even the chain can be balanced. Where do you stop?Good point on the gears balancing as well Fubar. Is Jon going to balance the gears? It seems it would be a waste to balance the Cam and not balance the Gears!
