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.

I tested those coils back to back with my Bosch coils

They picked up 4hp when she was running pig ass nasty stank rich.

Where she was running .85-9L, they didn't pick up anything.

When she was running .75L and the where the Bosch coils where skipping, those coils picked up the ponies and didn't mis-fire

I ran those coils @ 3.5ms and had no issues. Running them with that many ms is high in the duty cycle, all that really does is overheat the coils. The LS2 coils have been known to auto-ignite and pop engines when cranking. I still plan on testing the LS2 and LS1 coils against my Bosch coils. I suspect they'll loose a little power compared to the Bosch and the QuickSilver coils that Vex mentioned
