Well, this was my first ever attempt at using fiberglass and it didn't come out great but not bad either.

Here is the link to all the pics

The metal pipe down on the bottom is my downpipe-ish thing that was on my car. It is mpretty much straight through piping with a little thing to muffle the noise a little. Almost a cherry bomb without the insides.

The color for the box totally doesn't look good in my car but I don't care. I was trying my hand at laying flames down.

One thing I made sure of,was that I used the stick air snorkel to gather air while the front of the box is also open.

It's pretty sturdy and I think it will last a while.
I also covered the exterior with foil tape to help resist heat.

 

I use tripod so i cant display it on other sites.

 

Did you just lay fiberglass ontop a cardboard example or something? Never quite understood fiberglassing, share some of your secrets! :-D

 

I made a template of the box andf made them into separate flat pieces. I then patched them together.

I did about 3 layers first.Patched it together. Then cut it to the exact fit then laid a woven mesh of fiberglass on it to give it strength.

That was my first ever try and I can do much better now that I understand it.

 

What was the cost of messing around making something like that?

 

Well I used about 3 packs of fiberglass mesing around.
SO that's about $15(they were like 8 sqft)I stillhave a lot of matte and woven left.(custom autometer guage pod here I come!)
and I got the big gallon thing of resin for $50. I used about 2/3 of the can cause the resin would set before I could use it all. and probably like $10 in cups and brushes. then like $5 in hinges and foil tape.

I didn't care about the cost though. I was practicing glassing.

You could probably make the same box out of air ducting metal sheets for like $10-20

 

Hey that turned out really well, especially if it was your first time messing with fiberglass. That might be something I'd like to try out myself now that I've seen how well it could turn out.

 

50 bucks a gallon?!?!?!?

I got my two gallons for my bumper grille duct project for like 22 apiece at home depot.

 

It was a big jug but yeah that's pretty pricey. I know my stuff more now and won't be ripped off now.

 

Maybe it was Epoxy resin as opposed to Polyester (usually just called "fiberglass resin"). Epoxy is like 2-2.5x more expensive than Polyester and is not much stronger. I think the main difference is that it does not shrink after it cures like Polyester. I learned all this from my days of dreaming of building a Dragonfly, which is a Burt Rutan inspired homebuilt airplane that has no tail but two main wings. It is a radical plane that cruises at 200ish mph on 100hp and carries two people. A perfect candidate for a one rotor "7.5b" engine

Does anyone have the link to that guy who made that killer air box? The one that he put rotary power on it. And the thread keeps surfacing all the time. HE made it out of alluminum and got it from some website that sells alluminum for airplanes. If anyones got taht please tell me, i've been searching for that thread for a while now.

 

I made one for my 87 FC out of ducting sheet metal from a place not far off York St. in Houston. I had them cut me a few pieces that had insulation glued to them, so I had an insulated custom air box fed from a ram in the air dam.

 

it would be 6.5b. 1/2 of 13 is 6.5
