I see 3hp for $99 being an amazing deal at that level. 3hp adds up to a lot in a 500mile race. Besides you also get the added benifit of having a more reliable engine. So what's next harmonic dampeners for cams?

That being said where would you do the balance adjustment? Certainly not on the cam lobes themselves nor would you want to drill at the cam bearing location. So what is left to drill? Not much.

That's what valvetrain harmonics can do.
We see HP gains on balanced cams from 5,600rpm on up.
On Hydraulic roller cams we see as much as a 400rpm gain engine rpm.
