Ok, i've done a lot of reading, and just a couple of small things to clarify,

I've been looking at a msd setup, mainly because I want to have a rev limiter for my autoxing and not worrying about blowing up the engine. I've looked at hyperformance's setup, and also at other comments. I guess my question is mostly about the coils, I know there is the three coil setup (as i've read on the mazspeed.com page) which i can run with stock/msd blaster/accel coils, 2nd gen dual fire coil, or i can also run the msd dis or the gm dis or the accel version. My question is, which is better? and what can i expect performance wise?

 

You may have some problems with a rev limiter unless you run the same unit on all sections of the ignition. IE an MSD for the Leading and each Trailing coil all set to the same rpm. Maybe someone who has tried this will chime in.

 

I know nothing about MSD, but i thought i'd chime in and say hi to Alvin.

I know Chuck recommend twin MSD boxes, it makes a lot of sense.

 

makes sense, but that's pricey to have two msds... =( hey matt, long time no see, how's the 7 running? doesn't the trailing ignition go off after a certain rpm anyway?
