Part 18 – Heat Shielding

[diegokid]

On the front of the drivers footbox did you use spacers to keep the master cylinders from "crushing" the panel with the air gap?

I left a 1/2" air gap behind the aluminum. The master cylinders are not going to mount on the front of the foot box. More on that later

Oh the suspense....!

I'm new to the Cobra world and this forum. I'll be at the May 14th Homecoming to look at all the Cobra's and work my order details with the Weaver's. I'm a big planner and therefore why I'm looking for all the build tips I can. In this "Heat Shield" post, did you consider LizardSkins Sound and Ceramic heat coating? If so, any opinions of the product? From my research, looks like the sound coating would be sprayed on the body surfaces and the ceramic heat sprayed on the back of the aluminum. Any help here much appreciated. Thanks Mark

I did not consider Lizard Skin but it looks like it would do a great job. One of their vidios showed the product sanded, filled and painted so you would not need the aluminum shield. I was able to fabricate all the pieces myself so my cost is very low in comparison, also I'm running a small block so the extra room in the engine compartment translates to less heat to control.

Another thought on heat shielding that I'll be doing in addition to everything else. I'll ceramic coat the headers and then wrap them with header tape wrap. Many benefits come from this, but the top two are, 1) Heat to drop in the engine compartment by up to 70% and 2) with the heat staying within the header, thereby keeping the exhaust gas hotter, flow restriction decreases. Both 1 & 2 contribute to more HP.... always a good thing.

The problem with header wrap is it holds moisture, I have replaced several sets of headers over the years that were wrapped, they literally fell apart after a few years. If you ceramic coat your exhaust and use Thermo tec heat insulation under your carpet you will not have a heat problem.
