Never said it will reduce energy,
Saturation will produce max energy, not max volatge as the coil take a longer time to move down the hystersis loop.
So the peak voltage is lower even though more power is given.
Richard from omex was telling me how thay had the same problem, they were using 1ms dwel and getting plenty of power from that. Wish i could remeber which coil pak they wer using.
A coil pack from a turbo engine (not limited to ford models) will probally be designed to have more voltage.
