Ignition Thoughts/Ideas/Recommendations

NoDOHC · 09-17-2009, 09:19 PM

If I could get a set of Mercury IGN1-As for a decent price, maybe it would be worth going E8 (that will have to wait until next years budget).

I won't have a full 6ms for an LS2 coil (I intend to rev to 10,000 on my next iteration, if I can light the charge).

Does anyone know what the saturation energy of the stock coils is? If not, I will get an oscilloscope and find out. I would like to be sure that I am significantly upgrading ignition, as the stock coils seem to ignite very well at lower revs and I can run them at higher voltage to get over the rev issue.

Just bought 4 of these to run with my P1000 and E85.

I have run my own experiments comparing inductive to boosted inductive then to CDI based, as per a good Mazda test I found more power, lower EGT, leaner AFR (all indicating better more complete burn), on CDI than any version of inductive all other variables held constant. There is also a nice increase in RPM, again most cant test this on road/track.

Most who trash CDI or dismiss it have never run proper tests to back their views.

The best set up is COP, and CDI on all plugs, and wasted spark on leading
