MSD Blaster coil ok to use with MP orange box?

Just wondering. Seems like these places like to pair their stuff up with their own coils so I'm hoping this combo I have in mind won't let any smoke out.

I did it with mine.

As did I....Painted her semi gloss & added a coil decal From ECS....dont tell OK?

if you are mounting the coil horizontally use the Blaster Vibration coil , the regular blasters leak oil mounted horizontally

:o  Oops!  Lol!

In any case, I ran the orange box with blaster coil for years with no issues other than...leaking oil from the coil I guess... ::)

Ghoste

Too late here too, if mine is leaking it has to be about empty by now, lol.  Going to watch for that now though.

I've had that setup in my previous Charger R/T and now in my Challenger.

Sarcasm detector, that's a real good invention.

I have unplugged the coil wire on a few of the blaster & found the rubber boot full of oil out of the coil

never have got that... true I used to use an old Blaster coil, which is slightly smaller diameter than newer units. You can notice JUST when changing from an old unit to a newer unit, needing to unscrew the adjusting mount screw.

That's the one I have... and it's already black. :2thumbs: Hey Chris, do you have a link for that decal?

I think you have to change the ballast resistor.  MSD should be able to confirm that.  I'd double check with them to be on the safe side and see what resistance the coil needs.

They are recent members here too.

Well, I guess I'll be leaving it blank. Their date range does me no good since they only cover early 1969 to late 1971.  :rotz:

I'll send them an email. :2thumbs:

I think it may less a case of what it needs versus what it can take advantage of but checking with them would still be a good idea.

My M&H harness has the four prong ballast plugs. How are the four prong resistors different (other than the obvious)?

Chryco Psycho

the second side of the ballast reduces voltage to the ECU , unless you use an ECU from 72-75 it doesn't use the 5th pin with the reduced voltage so all you need is a single ballast between the blue & brown wires , the green wire to the ecu is not used

I've got the four pin ECU and plug. Not sure why the harness came with a 4-spade resistor plug but I guess I'll just plug it in anyway. Sounds like it won't do anything other than look official.

I've also got the four pin ECU and plug. I just plugged it in. Doesn't do anything but it looks good.

I don't think you would want to use the dual resistor, IRC the primary side of that resistor is 1.2 or 1.5 ohm and  you will get to low voltage to the coil. The 69 Super Bee I did with a M&H harness, I removed the terminals from the dual connectors and mounted them in the single connectors from the original harness and reused the original 0,8 ohm resistor.

Actually, I was wrong about my M&H plug. It does have five contacts but obviously the fifth won't be doing anything since the ECM has only four. Anyway, another thing I could do is gut the resistor on that side and run a straight wire for no resistance. Or similar to what you did, eliminate the terminals on that side of the four-prong resistor so it's not doing anything. Guess I should have gotten the two-prong resistor but I didn't know at the time.

I did read about using the Blaster 2 coil with an orange box and most people use a .25 ohm ballast. that way the coil gets a constant 12V - 12V while starting from the battery and when running the ballast reduces the 14V from the alt to around 12V.
