How to Make a Fiberglass or Carbon Fiber Airbox

A very basic tutorial for beginners showing an ideal first car project

[@simsneon2]

From a young fellow to older fella you taught me a lot thank you thank you very much for sharing

[@FZERO20]

This video is underrated and highly looked over. Will definitely build my intake system from scratch with home depot pipes. And thanks for your own info as well

[@Querencias7]

T E R R I F I C engineering, design and creation! Very ingenious indeed. Thanks so much sir, for sharing. Best to you.

[@MegaROCKY001]

Bill you have a very creative mind and that is the trick. You can know everything about fibreglass but if you can't create.....

[@CrazyCowboyBuilds]

Good stuff. Fabrication is a skill so few have these days!

[@heitorbernardes7977]

I'm amazed as how only Australia got the CDI right... Bill, i really admire your knowledge, keep safe and keep giving us very useful advices as always!

[@inronism]

Awesome job, did the box reduced any intake noise?

[@adityanarayan5742]

This is so cool! Thank you for giving me ideas to make parts in my living room :')

[@docteurtwin]

I love the ease with which you treat the subjects you produce 👍👐

[@matthewruss5008]

Another great video!

[@_Marthinzen]

Excellent!!

[@powerRods]

awesome thanks show youtube advance auto smile ....

[@FZERO20]

Dudeeee this video is amazing omg

[@Fantasia9399-y7q]

How do you prevent rain water from going in?

[@duncanmcrae750]

this is great - but just a clarification for you on gelcoat vs. flowcoat. Gelcoat will stay tacky while exposed to air. Flowcoat has wax in it (you can make flowcoat by adding wax), which floats to the surface after application, thereby isolating the styrene from air and letting it set. The reason you want a tacky surface on gelcoat is so the subsequent (fibreglass) resin forms a chemical bond with it.

[@BillsBuildandRace]

Thank you - that's all spot on. I did already personally know that as my last job was with Australia's largest (& possibly only), manufacturer of resins, flowcoat & gelcoat in Australia. In making tutorials for absolute beginners one has to avoid over loading them with too much information initially, and then leading them progressively deeper as their experience & knowledge grows with my "Masterclass" level tutorials. But thanks.

[@dubtechbrotherstv5744]

This was extremely inspiring 👌🏻 great work 👍

[@Lordvoldemore]

Wow that box 👌

[@obhenx]

Old skool wisdom.... thanks for sharing!

[@malicieu247]

Hello sir, I am also starting as a DIY when it comes to car mods. Just nowhere near as skillful and knowledgeable as you. Seeing this videos though gives me new ideas. Thank you for sharing this to us ! Regards from Canada

[@markrobinson8575]

Your welcome

[@johnnyboydianno]

Awesome

[@jackzhao604]

How does this hold up against heat under the hood? When I search on google it all says fiberglass has a very high heat resistance but would it be the same if I home made them with basic materials?

[@BillsBuildandRace]

It is a myth that fiberglass will ignite under the hood. Put it directly on an exhaust manifold and yes it will, like almost anything else. I have been running fiberglass parts under my hood for over twenty years with no problems regarding heat whatsoever.

[@jamezclowdz1203]

Love the carbon fiber o get what your saying about pods but what if your planning on a forced induction and tuning

[@zschow9259]

its frggin' awesumm…...but does it fit in the carrr????!!

[@leoyru.3361]

why not using the plastic pot directly ?

[@razif6916]

Great..subs added

[@Repent-zd8xr]

I am addicted to you're channel 😱

[@chvydrptop]

Man that pot re-purpose idea is brilliant, I have a cone shaped air filter that will work great with it! Thanks for sharing. Is there anyway to make the final coat over the carbon fiber smoother?

[@blackgold1111]

Great tips. Nice video.

[@dieselwillie1628]

Awesome DIY, I’m currently building a VW TDI air filter box to fit my VW van; similar to your second Honda filter made with the square filter. I’m thinking of building the box first in CF then drill the holes. Then make/buy some CF tubing to epoxy around the holes. Did this cross your mind? Thanks for the inspiration!

[@stephxryan]

I seriously thought it was a joke when i seen the pot but then you took it all out and it looked really good i was so shocked and that you are actually very creative what a great idea and imagination really kool ☺ i subscribed to see what other ideas you can give me absolutely brilliant sir 👍

[@jamezclowdz1203]

That second one was so cool but that wood work takes some skill to get it all perfect like that good work...I'm still trying to learn the basics did you use any release agent on the mold?

[@yycfoodie5668]

great video

[@CaptainAmerica-ve7cd]

Very inspiring sir

[@michaelsmith8060]

This out of all the so called hp making bs ones is the bomb. Im gonna copy what hes done but bigger my hemis engine bays like an oven

[@chrisalex1440]

What would you make the back of the pod filter out of

[@MitchellGuyon]

Love your work, by the way

[@DarkForest86]

Super cool

[@JOEGGGJOE]

what brand is that finish coat? did you have to sand or scuff the fiberglass before putting it on. great video.

[@BillsBuildandRace]

Trojan from their Newcastle manufacturing plant where used to work. In other countries it's also called "Top Coat". You don't HAVE to sand or scuff for great adhesion, but I always sand with 120 discs to get the smoothest finish before top coating. Another method is to make an extra top layer of 6 oz. woven cloth as used by surfboard builders. This eliminates the "hairy" finish of chopped strand mat (csm), but it doesn't work well on multiple curved surfaces because it is woven.

[@JOEGGGJOE]

oh ok, im going to look into that. why dont you use fiberglass tissue paper. its like a thicker veil. i never used it but its for a smoother finish.

[@Averagegunenthusiast]

I did it because I didn’t have another choice, when you swap a modern engine into a classic car that didn’t have an air box.

[@tomchristensen2914]

How do I keep rain water from reaching filter

[@blizteredthumbs7911]

You're a flamin' mangral but cheers, this helped a lot :) bought a rally car a few weeks ago, looked at the feel and sound and knew there was something a miss. This is my project for this week! Inaccurate pressure :D

[@ratgreen]

This was the video that originally made me subscribe to you.

[@Robis_Grigoris]

[@ReddList]

What epoxy resin do you use for your Carbon? I assume you aren't using Wattyl 7008 like you do for sealing, but I'd love to know. The internet makes this all too confusing. Thanks a bunch!

[@BillsBuildandRace]

I use two pack basic epoxy resin for carbon & Kevlar layup.

[@lucasmonks5767]

This is why I love Australia

[@Aviationrcfpv]

was that last part filmed down from the mechanics at Bennetts green i worked at bradnams

[@BillsBuildandRace]

Yes!... David Brown tuned that motorkhana special I built and gave us permission to film a fang there early one Saturday morning in 2007. Incredible someone picked that!

[@Aviationrcfpv]

how long ago was it

[@mrclose5885]

Nice

[@mikerothfuss8020]

May I ask what your take is on rust repair with fiberglass?

[@BillsBuildandRace]

Success depends mainly on two things that most home mechanics overlook: 1) Find the source of the rust. Why is it happening? Where is the water coming from? Make sure it can get away after your repair. 2) Adhesion. Putting a fiberglass patch on failing metal will result in it eventually coming away. Grind all rust away. Prime the metal before you apply fiberglass. Cover your fiberglassing with Top/Finish coat (NOT Gelcoat), then a skim of car body filler.

[@Super-jk3zt]

That song made me feel tired of losing, thanks.

[@mikerothfuss8020]

You sir, are awesome!

[@PhortyZips]

agreed

[@THOMASTHESAILOR]

Can you use "Oven Heat" to cure polyester resin on smaller parts.?

[@BillsBuildandRace]

Why?

[@palauso3863]

WJP004 Whats the brand and name of the gel coat that you use? and the finish coat as well?

[@BillsBuildandRace]

Where are you?

[@williamduffield4964]

Hi WJP004, hay just to let you and your viewers know, that is not a PVC stormwater fitting, it is a PVC waste water fitting, for those people wishing to try this go to your local plumbing shop and ask for a 100 by 50mm LIT (level invert tapper) and the other fitting a 100mm floor flange, and yes I am a plumber and yes I am into cars because cars are a shit load better then plumbing.

[@BillsBuildandRace]

Hahaha... glad I could combine the two for you.

[@orlandostead8703]

Great video, about to rectify the mistakes of some young tyro!!! 🤣🤣🤣

[@bbbildhuu]

Love it

The copyright people have hit you hard lately.

WJP004 Just imagine how nice world may be if they had a useful work... so much wasted effort.
