Redressing a controversial subject...
I highly recommend the big yellow square-top Accell Super coil.
Mine operates from an easy running rpm of 500 to 7500 without a hick-up,
and car has gone 93 mph in the Eighth with it.
And has been on the car since 2002 at least.
If I pull the coilwire out during cranking, it looks like I could weld with it.
I make absolutely sure that my fuel system is NOT leaking; no joke. that coil will spark anything flammable on fire
I think I could set the neighbors grass on fire from a hundred feet away ........................ lol.
How much voltage does it produce?
Don't know/don't care to know.
How many amps?
Don't know/don't care, it sparks dead reliable from cranking rpm to over 7500, so what more could I want from an ignition system.......
Car won't go any faster with two of 'em, and even if it did, there are not many places to get into third gear at WOT, besides the track..................... which don't interest me.
But ya know, I run it off a relay, cuz my 32 YO Duster wiring harness (in year 2002) under the dash was getting a lil smelly on Day-1, lol.
Accell Super, the big one........ for the win.
I put mine out on the apron with a 30" wire. When I spend the night in a Hotel, 500 miles from home, I take the wire with me.
