D585 is the ones that discharge if you leave the dwell settings too long correct?

Yes. Watch the aftermarket replacements. Some don't like higher dwell and are more prone to that.

1000 isnt that much. Im talking more like 1500hp

D585 is the heat sink coil? We dont use those because of the wierd discharge never want to take the chance

Amen! I'm not having any issues with the d585 on e85, but switching to methanol and will be switching to ign1a coils as well. But like others, make sure you get legit ones
