[QUOTE=lowntegra;2202149]-94mark3: received your email, will reply tomorrow.
-isport: I am making these (so far) with an actual bumper as the mold. I guess that would be a female type mold? I would love to hear your input & ideas! I am planning on buying some better vacuum bagging supplies tomorrow, peel ply, breather, and a stretchier bag material. Where do you get your supplies from? I was going to use one of the online composite sites… Thanks - bryan[/QUOTE]
I get all of my supplies from an industrial supplier. All my stuff come on an 18 wheeler. Unfortunately for smaller guys, they don’t even carry things in anything less than bulk quantities.
A good place online is fiberglass supply. their prices are reasonable.
as for what I think you should do from here is this. take the last one you made, and make a mold of it. ducts are one of the only things that ever need a male mold.
email me at info@isportcomposites.com and I can help you some more. maybe we can do this project together.
so, finally got some pics of how this looks on an actual car… big thanks to Shane on that one!
also, bryan @ isport has been helping as well.
as far as fitment goes, i know there is a small lip on the back edge of the stock bumper you have to trim off, and move the horn & trim away the metal tab that it used to bolt to. relocating it shouldnt be an issue at all.

That does look good! Although I don’t see how it can actually be used as a duct, currently it’s just something to cover the opening already in the bumper. It needs something on the backside that tapers down into a circular shape that you can attach a hose to it and direct it to your brakes or intake. And once that’s worked out, you should design the same thing to be used on 92-93 bumpers - although it’d require removal of your bumper lights. It’d be rad if a duct was made which secured to the bumper the same exact way as the bumper lights do. That way you can install/remove it easily for when you’re at the track.
^ bingo! exactly what i plan on doing, im gonna get this front piece dialed in. i want the finished part to be nicer, & easier to make. then i will start the “back” part to it, that piece to transition from the kinda rectangle/oval-ish bumper hole, to a 2.5" or 3" round outlet. fom there, do exactly what ya said, stick a flexible air hose on it, & run it either to the air intake ,or brake duct cooling…
It would also be a good idea to angle the back side UP towards the air box as you mold it. The radius is a tight one inside the fender area and smoothing it out would help with air flow. My scoop goes from the back of the scoop straight into a 90 aluminum bend… I would have loved to used 2 45s to smooth it out some… not that my car is any where near “high performance” just my tinkering place…
Awesome. Before you start working on the “back” part of the duct you should look at the various sizes of hoses available. And definitely look at automotive specific ones because they are made for automotive applications and thus are built to withstand heat…etc
Wow. This is quite nice. I’d like to see someone do something similar for the 92-93 bumpers as well. As long as the scoop followed a nice contour of the lines, it would look really nice.
okay guys, supplies have been ordered, waiting for them to come in. this should make the next batch even better! hope to have these started by the weekend, as long as the new stuff gets here.
flexible hose ducting, for either air intake, or brake cooling… are we thinking this?:
(it’s high temp silicone)
flexible would make the process easier, but solid would be “nicer” IMHO. it is pretty easy to direct the flow up to the bottom of the airbox with a short 90" turn and a silicon coupler. But it is your car and you can do it either way you want.
short and easy… and likely less expensive than the hose you linked to. If you are looking for brake cooling ducts, then yes, I would use a flexible hose for that because regid would be more difficult to work with for sure.

I second what colin said above about the different tube sizes, I have a 00 jdm type r so my throttle body is 62mm for now until I upgrade to a 68mm. Id like to have a choice in duct size if its possible. Maybe if the duct back side started at 3.5" and got smaller to 2.5" the longer it went back, that way we can trim/cut off to the 3.5" section and add our tube/pipe of choice and clamp it.
so any idea when this will be on the market, also any new updates on its developement. I really wanted to know what its inlet diameter is going to be, im trying to go into a all motor build so If the rear inlet diameter was 3.5" I think that would work…
thanks alot for all the support & interest guys! i really appreciate the enthusiasm! ok, so it has been longer than i wanted since my last update…so i finally got my shipment of suuplies to start the male mold of the duct (should make things alot simpler & quicker to actually make the ducts.)
after i get the mold going, i am planning to start the rear section. i am still brainstorming ideas on how to physically connect the rear part, to the backside of the bumper…? any thoughts? tiny screws? double sided tape? velcro? ideally, it shouldnt disrupt the airflow into the duct/outlet assembly, so i dont want any screws protruding into it. i am unsure if either double sided tape, or velcro would be secure enough to hold…i want the fit to be nice and snug around the inlet flange.
I will second that!
