View Full Version : MSD Digital 7 Plus

I recently purchase the MSD Digital 6 plus and lend it out to a friend that has a turbocharge 4AGE 20V silver top.
I have a 1986 Subaru 1800 GL with some work.
My ignition combo was MSD Digital 6 plus, Nology M80 coil, Nology Hotwires.
I find that I can run more fuel, resulting in more power.
My street use is not much. It takes me 12mins to get to work and so on.
I am thinking of getting the MSD Digital 7 Plus.
Would it last long on the street?
What part of it would likely be damage if using it on the street?

The Digital 7 Plus can be used in the street, but it would depend on the coil that you will be using. The Nology Coil may not be the appropriate coil to use with the Digital 7. We would need additional info. in order to find out if the Nology coil will be appropriate. Although we do offer the PN 8207 Blaster SS Coil, PN 8251 Pro Power HVC Coil, or the PN 8261 HVC II Coil, either of these will work fine with the Digital 7. Keep in mind that with the additional current and voltage you may have to keep an eye on your cap, rotor, plug wires and spark plugs.

I will be changing the nology M80 coil which can olny handles 600mA.
Ok. I get you. It sounds good.
I have ngk racing plugs. How would excessive current do to the plugs if I am not running boost or anything so?
Also, would the box overheat after 30mins of racing or so?

When using a standard set of plugs, this could burn the center electrode due to the current which is heat and energy, material is burnt and wears out the plug quicker even under normal compression.
The unit will not overheat when running with the right coil, it will work fine.

Ok. Thanks for the help.
Are there special plugs for this type of enviroment?
Since I am using racing plugs from ngk, I do not see any problems arising.
I normal change plugs every 3 months. So, that might not be any big deal.
Thanks again for you wonderful help.

I would stay with the NGK plugs, they are very good and should work great on your vehicle.
