Blaster Coil Install Gone Wrong.


Recommended Posts

Due to a recent turn of events I cant spend much time at the house. So I went and got some mental down time working on the 850.

I fabricated and painted a killer braket to hold the MSD coil and removed the ignition control module from the factory bracket.

Car runs great for 1 day. This morning I am about 2 miles from the house on my way to the office and the car just dies. Right there on the spot....dead. In the middle of rush hour traffic. So I get out and pop the hood and a nice little woft of smoke comes from the coil area with the ever present smell of burnt plastic. Yup, the module is fried.

Apparently the bracket it is mounted to has a zinc oxide heat sink seal that keeps the little unit from cooking itself.

Sooooo, 230.00 later I have a new coil and module unit and a new plug wire. Back to stock I go.

Just for clarification, what exactly happened? The coil overheated? What's this about a heatsink?

Sorry bro :(

The ignition control module is the little black box that is attached to the same plate the coil is. On the back side of the module is about a 1/2 by 1/2 little square of a subtance known as zinc oxcide. This stuff help dissapate heat of the small electronic units inside the module. They are very sensitive to heat. If they cook, your engine dies right there on the spot. It will crank over but will not start.

I have a MSD SS coil and I use my OEM coil too!

Heres how its done.... I have my OEM coil and connectect off the coil wire side is a Jacobs secondary trigger http://go.mrgasket.com/pdf/380468.pdf

next I connected the output of the trigger into my MSD boost timing master

http://www.msdignition.com/tc_19.htm from the output of the MSD boost timing master. I then connect that to the input of the SS coil.

This way you never remove the OEM parts and you never run a chance of burning up or wiring things wrong.

You can wire from the secondary trigger right to the MSD coil and still keep the OEM coil.

Thanks for the heads up man!

When I installed my MSD Blaster Coil I had also considered moving that portion. Fortunately for me I left it where it was and just lengthened the wires a few inches to reach my install point.

Here are some pics of where mine is, on my EST Intake heat shield. The closer second shot shows the part in question, I'm pretty sure.

Yep, its a PCV breather oil catch can.

I lost a few inches of vacuum (down to about 18) when I installed the first can that had a breather filter on the top. The JAZ can that is mentioned in this site's performance mods instructions. That can is crap. The fittings suck and fall apart before you can even get it installed, there is no way to see the contents and the filter on top means oil vaper all around your engine bay where ever its installed. The drain at the bottom seems handy, however it is completely *not* functional as soon as any oil goo makes it to the bottom of the can which is pretty much right away. I suppose you could remove the filter at the top to check its level, but thats a hassle.

So I bought this cheasy bling bling can because I liked the design. Its sealed, no filter and has a site glass on one side for level check plus an o-ringed anodized cap that is quick and easy to open with no tools. It also has a large enough hole that you could turkey-baster out the contents if you so desire. There is a drain plug at the bottom if you want to plumb in a fitting with a valve and route a hose out the bottome of the engine bay. Its incredibly light weight and the fittings are welded, no leaks. Its polished and very shiny, which I don't care for but I'm sure some people like. Comes with the mounting bracket also.

I ran copper pipe from the PCV can under the battery tray and up to the can. Then the other line goes to the stock location on the intake pipe, where the vacuum reference line is and the electral heater connector. This setup works *perfectly* and now I pull all 22 inches mercury of vacuum at idle.
