To be honest with you I have no idea. I haven't messed with too much alpha stuff. Had a 22' Chaparrall with a 330 Tempest and alpha that had no cooling issues. I do have a restrictor inside the bypass hose to the thermostat housing. It has a 7/32" hole in it so most of my water is sent through the engine.

You don`t need an additional box to run coils.
HP and Dual sync is all thats needed.(and a couple subharnesses)

Oh, I thought you were doing coil/plug.
Not sure on that then..I`m running 8 coils.

After doing 15 mins of research they are a "smart coil" that does not need a box. But it appears Holley has a coil driver module to drive a regular coil.

Go coil per plug.
Better hotter spark, you can control individual timing on each coil if you wanted to .. I run a dwell map based on rpm... no need to fire those coils on full blast at idle..helps em live longer.

+1 on the coil for each cyl. if you can swing it, I would think it makes a lot of sense!

I'll start looking for the best pricing on some D-585 coils. They seem to be good to 15# of boost. I'm under 600HP and NA.
