WILL SHO U
Sooner or later
Im getting ready to fix by broken DIS, is it just take old one off and put new one on or do I need something? Thanks.
Anything special to installing new DIS?

Just some heat sink compound... (or dielectric grease if you can't find the heast sink compound)
just make sure you don't go too crazy with it around the bottom mounting holes.

I wouldn't put dielectric grease on there. You can go to a computer store and get some thermal paste. I was going to put some of my Arctic Silver 5 on mine, but I had so many little tubes of the stuff Zalman gives so I just used that.

Hey Where's my post?
rut row!! The classic debate begins! :corn:

Im not going to debate anything... Dielectric grease works... granted its not the right stuff to use... but like I said, if you can't find the right stuff, it works...
Dielectric grease is not made to transfer heat. It is made to keep terminals and such free from debris and corrosion. The idea of the thermal compound is to conduct the heat from the DIS onto the aluminum intake with the "cool" air running through it.

Every Radio shack in the US carries heat sink compound and incase you find that one that doesn't then any electronics parts seller will.

every single time I have gone to RS, they have been out... which is why I run DiG.

Take caution not to crack the unit itself, as the wire harness's clips are extremely rigid. By the way, where did you come across a new one?

Yes folks-dg is not a heat barrier(anti corrosion only) so use the heat sink paste-if you don't the intake heat will bake the unit. If you buy a new one then it should come with a little packet of the stuff. Spread it on and use it all.-

Or goto the suntan hut and get some zinc oxide...you know..the stuff lifegaurds put on their noses.

It just needs a good ground , the heat is not something to worry here.
Yes it is. Under the hood of a SHO gets quite hot. Do you know the #1 cause for electronics to fail (under normal operation)? Yup, it's heat. Thus why the EEC is mounted out of the engine bay. The DIS gets a good ground through the mounting bolts. That is why there is metal throughout the mounting holes of the DIS.
You do realize that heat sink paste transfers heat and not blocks it, right? Not only that but when you use a TIM you are supposed to use the thinest layer possible. TIMs transfer heat. If you use Artic Silver or the white stuff or whatever you will be more effeciently transferring the heat from the intake to the DIS. If the DIS gets hotter than the intake then the opposite will occur. I highly doubt the DIS gets hotter the intake when the car isn't moving though.
Last word I heard on it is the manual calls for dieleletric. Now when you are talking about 200+ degrees a thin layer of that will not block heat transfer. It will just not be as efficient as a TIM.
For all practical reasons people have put everything from nothing almost to peanut butter on the dang things and I haven't heard a complaint yet about their DIS causing the car BSODs.

And then after your run on the drags how much heat is transferred from the intake to the DIS? 300 degrees? 400 degrees? What's the DIS' operating range?

lol, thats what i used. only stuff i had lying around. damn expensive

The crossover section doesn't see as much heat as the runners and plenums. Most of it's attachment to the rest of the intake (aside from the brackets) is a rubber hose.You do realize that heat sink paste transfers heat and not blocks it, right?

However, if you're at the drags, most people open their hood after a run.
Good call on the rubber part. I forgot that the heat needs to go through the hoses connecting the runners to the plenum and then the hoses connecting the crossover tubes. I would still be surprised if the DIS got hot enough internally to be able to sink heat into the the intake.
I'm curious, if you were able to ensure a good remote ground if one could attach the DIS to the strut tower and run a diode between the surfaces to find out how hot the DIS actually gets.

Tom would be a good person to ask on that. He's installed his DIS completely away from the motor.
