Who's your carbon fiber supplier? I would like to try making some items myself...namely the carbon fiber airbox. You have me eying the same Rotary Works v-mount now for myself...although I just bought an SMIC.. argh!

I'm sure you heard by now that I sold my 8 for an FD? It's a tight fit for me! I sure miss Arizona as well, but Colorado has been treating me well.

I did hear you've got an FD now -- thats great! Too bad though about no more 8 -- I hope it went to good owner. That was a nice car too.

I get all my carbon fiber/kevlar/fiberglass/resin supplies from US Composites (uscomposites.com). Theres also tapplastics.com

I bought this book a couple years ago:

http://www.amazon.com/Fiberglass-Oth...dp_ob_title_bk

Also, I found a couple online forums that are good to lurk on and read the stickies:

www.fiberglassforums.com and www.racingcomposites.net

Expect a lot of trial and error-- theres lots of little details you only find out about when you try things. I've thrown a lot of failures away. It can be very time consuming.

I may consider that, but definitely after I finish the rest of this. I would need to tweak my process since it took a ridiculous amount of time doing the CF/Kevlar demold. Basically I had to destroy the foamboard mold by chipping it out with a flathead screwdriver. For some reason my parting wax didn't work well on the foamboard.
The very porous nature of the foamboard probably sucked up some of the mold release wax or the resin itself. I've had good luck covering it with wax paper or tin foil. Wax paper seems to work better as it doesn't want to crinkle as much.

The foamboard had a glossy paper side which is what I applied the mold release wax to. I have some other stuff I probably should have used called "PVA" which is basically a thinner version of elmers glue that can be shot out of a spray gun. When it dries it ends up like a protective garbage bag around the part that peels off like skin on a bad sunburn. Its really awesome, I don't know why I didn't use it.

I got the aluminum bottom piece of my airbox back from the welder today. He only tacked the 4" piping in because I was afraid things may not line up right but it seems to all fit perfectly:



I also had him weld in a section of aluminum tube I rolled some 1/8" NPT threads on both sides as a water/meth injection nozzle coupler:
