Ignition Thoughts/Ideas/Recommendations

They list ignition energy in Volts (should be in Joules).

I would want to know what ignition energy they will supply.

Ignition energy: Energy is the area under the power vs. time curve. LS2 Coils are about 120-130 mJ

The voltage is comparable to the LS2 coils (they make about 75kV).

LS2 coils are cheap. (I paid $75.00 for 4)

Off the top of my head, I see no advantage between these coils and LS2 coils other than it appears that these would take a lower dwell time (about 4 ms).

The LS2 coils like 5.5 ms. = 6 ms cycle time = 10,000 rpm max.

4 ms = 4.5 ms cycle time = 13,333 rpm max.

Obviously, CDI can rev much higher, this is it's biggest advantage over inductive.
