So no one likes actual data? Look at the graph I posted. It gives up nothing down low. Zero, nada. It’s absolutely nothing like a single plane which would throw away 15-20lb/ft compared to an rpm air gap or LD340. It’s a worthy mod that extends the power band up on a dual plane. I’ve also noticed it widens the tuning window a little as well. It doesn’t turn a dual plane in to a single plane, It makes a better dual plane.
