I asked this same question under the general topic, but i also want you race car people to look at this as it is a little bit af a specific racing question, in a race car.



ok i have aftermarket 60,000 volt coils in my 2nd gen drag car, running a carb.(coils from Sumitt racing)

I have had the ignition setup in the DLDFIS, or what ever you call it (the Dual Leading Direct Fire Igntion System) and i have had it in stock configuration. (for a first gen)

(first one with 3 coils, and second one obviously with 2 coils)

my question is, has anyone had any problems with coils not intended for a rotary, (is there such a thing).

the reason I ask, is because my new engine does not seem to run very well, mostly at high RPM's, i am wondering if this might have somehting to do with aftermarket coils not keeping up with the high RPM's of a rotary.

another reason i ask is when i am at higher RPM's (like 6-7k) the tach starts to freak out, (pegs 10 - 12,000)

does anyone have experiance with this?

thanks!
