DIS Module

Ok, so many of you have seen my ignition module mounted like this:

and shared your opinions on it not being the best idea, and I found out the hard way that it can overheat over in that dead air area and make it run like crap on a hot restart. I believe I fixed this issue saturday, I made a new mounting plate with the intake pattern copied in it to imitate the stock mounting location but figured there would be more airflow mounting it up instead of down, which meant mounting the module upside down which shouldn't be a problem. The mounting plate is 1/8" aluminum cleaned before the thermal transfer compound was put on, also picked up 3 computer heat sinks that I mounted on the back side. I'll try to get a picture tomorrow.

I also learned something about the ignition module. It's mounted with 3 bolts from the factory, DO NOT mount it with bolts in the 4 holes!!!! If you do, the engine won't even idle! Also, if anyone needs it, the threads are 4mm.

Did you put dialetic grease under the DIS when you installed it?It doesn't look like you have a good ground with your plate,does it run ok?

I used better, I went to the computer store and got thermal transfer compound like used under heat sinks on processors...

That was my old setup, it wasn't grounded yet worked fairly well.. The new setup is grounded because it's mounted on the intake, but I was going to add a ground wire because it isn't a good ground.

We our DIS on the race truck by itself with no screws in it then we ran a ground wire to the left corner anf right to a frame ground.Never had a heat problem after that

Interesting, you probably have more airflow on yours than I have at times though, time will tell how it works.

Here's the new setup:
