Heat Shield..again
<center><img src="http://
"></center><p>I don't think that the cardboard I used will ever catch on fire if you look at where it's located within the heat shield. However, the intake-side of the shield is still kinda hot and I want to minimize the amount of heat on that side (note: intake-side air is noticeably cooler, but not the shield itself.) Would painting the engine side with heat resistant paint be useful? Someone on here said that air is the best insulator, but if that were the case then people would stop putting insulation inside the walls of buildings and houses. Like I said, the intake side of the shield is still kind of hot, therefore warming the air on that side through convection (i think is the correct word) and if I can minimize that I can get the intake-side air cooler.
Again, thanks for any advice or suggestions on this.
The pics, thanks for whoever sent me the FAQ on this.

Dead air space is a great insulator...
without fiberglass insulation or some thing similar you get convection movement of the air. You also don't want something that will conduct the heat.

But, but, but...
...cardboard does have dead air space in between...doesn't it? Is there another material I should use? I just thought that 2 sheets of sturdy aluminum with some cardboard in between would do the job. And possibly painting the two sides with heat resistant paint. How are others doing it?

right, but cardboard still will conduct heat... that's why everyone was bugging
you about it lighting on fire.
I don't think that will happen, nevertheless I would not do it.
Why not just remove the cardboard? you're intake side will be cooler

what is the temp outside?
I doubt there is a lot lost or gained with your setup. When I had mine cone filter on a 60 degree day (or cooler) the filter would stay cold to the touch.

Yes card board does have dead air space, and does not conduct heat well...

The paint I would consider using would some thing that would reflect the heat to prevent the aluminum from absorbing the radiant heat.
But what I did to reduce underhood temps was creamic coat everything that generated the most heat. The manifold, turbo, cat and DP. I had Swain Tech do half the stuff and Jet Hot the other half. I will never use Jet Hot again, cost was about the same as Swain but the Swain product was far superior to what Jet Hot offered.
For a few bucks you could buy a cooking thermometer to quantify your changes. This you could stick to the hood of your car, tilt the display and still read it while driving. (This is the one I bought works great for meat after your car is done with it).<ul><li><a href="http://www.bedbathandbeyond.com/product.asp?order_num=-1&SKU=11720307&RN=210">linked</a></li></ul>
