A higher voltage should find it "easier" to jump the gap under higher pressure/compression (which is effectively what boost gives you). Maintaining the same energy requires more current. We tried 12v straight on the coil an no difference. The plug gap on the Z7U engines is exactly the same, Bill. The plug isn't though...
