RE: ** Update pics 15% power gain with resonator
Same idea, same principle, same math! just a different way of "storing the charge" at a certain frequency. You should have realized that from the formula I posted, It is the same formula that was used in the two web pages linked to. A resonator is a resonator, name and location don't change what it does. The math says so!
The dyno charts are very interesting, definate increases in horsepower at certain rpms, and a drop in others where you are working against the resonant frequency of the bottle or box.
