Well, today was a really nice day. Actually the first day in almost a week without rain. On top of that, work is slow, so I stayed home to get some parts in order and get some ready to send back.

So after I got done with all that, I decided to start working on a heatsheild. I know about using the trash can or mailbox even, but I wanted something a little different. I don't know why... I just did!

After I finally decided that it would be easier to make a prototype out of some scrap cardboard that I had laying around. So I got to work taking measurments and writing everything down. Soon, I had something that actually looked like a heatsheild, on paper anyway. After making some adjustments, this is what I ended up with...



To see all of them, check them out here.

I know that it's not perfect. I mean, it's cardboard for crying out loud!! I do plan on making at least one or two other prototypes, like this before I actually take a stab at making one in some other material.

Through all this though, I am still at odds over what I should actually build this out of. My first thoughts were of aluminium, that I could paint with a coating, but I remembered someone saying that aluminium conducted too much heat or too well. So then I got to thinking of plastic. Easy enough. I have plenty of that. Some pretty tough plastic too. What kind? I have no freaking idea!! Only problem I would have though is making that nice curve on the bottom firewall side of the sheild.

Yes! I searched. I even searched the archives. Everyone just seems to say, "Make your own!". And most of time, they are talking about the trash can method. Although I'm not knocking the trashcan method, I'm just wanting something a little more different and custom. Something I made. Plus... it's cheaper too!

So I pose the question... "What material would be best to make this heat sheild out of?"

Seriously though - I would make the heat shield out of plexiglass with foam sealing.

Cardboard is the way to go to develop a prototype to get the shape down.

If you have the time/resources try making one out of aluminum and one out of plastic. Drive the car with each one and take a feel to see how hot it is. Not exactly scientific, but will give you a good idea.

Keep up the good work.

The DTec guys made theirs out of aluminum, of course, but they offered a ceramic coating as an option. The ceramic doesn't conduct heat and is easily painted over for an even more custom look. I have no idea where to obtain the ceramic in small quantities.

we do ceramic coating where i work, i think it may prove to be too pricey for the benifit (for those that don't work there anyway
i'll see if i can't work something out if enough people are interested

how much would a heat shield help you anyway...just curious

Wow! Thanks guys. I guess I can take this suit off. Those things sure are hot!!

Plexiglass - Now I didn't even think of that and I can get my hands on plenty of that stuff. I am very familiar working with it also. I can use a heat gun to form the bottom contour... but wait... I wonder just how much heat the plexiglass can actually stand up to? Umm. Guess I will have to do some investigative work there.

Aluminium - Well, I knew Dtec offered that ceramic coating, but really I'm not too familiar with that stuff. At first I thought maybe it was just a ceramic paint, but I guess it's not. Hey! I bet Hobby Lobby or somewhere like that has it. One other thing that sort of makes me want to stay away from using aluminium is the fact that I can't weld. I couldn't weld cast iron when I was in school. I would be sure to turn a nice sheet of aluminium into a puddle of molton liqiud in no time flat! And I surely wouldn't want to use JB Weld cause I think that might turn out looking tacky. I don't know...

Man... More investigative work.

Fiberglass - Now there is something that I have zero experience with, but the possiblities do seem promising. Still wondering about heat though. Shouldn't be too big of an issue since I have seen fiberglass hoods before. Also, since I have it bolted down in three places, vibration shouldn't be an issue. I was planning on using some sort of rubber gromet/washer sort of thing in those places anyway.

Man... Even more investigative work.

You know. This just might turn out to be one hell of a fun project. Thanks again for all the support guys. I will of course keep everyone up dated as things more along.
