97_luder Posted March 10, 2014 Report Share Posted March 10, 2014 Hello all. So i spent the weekend tuning my SUs and was tired of the stock air filter look. So I pulled out the laptop and I designed a custom pair of horns and printed them on my 3D printer. Let me know what you guys think of them. Thanks 2 Quote Link to comment
MicroMachinery Posted March 10, 2014 Report Share Posted March 10, 2014 I think I need to be your guinea pig for testing them on the west coast. 1 Quote Link to comment
97_luder Posted March 10, 2014 Author Report Share Posted March 10, 2014 I think I need to be your guinea pig for testing them on the west coast. LOL, I figured someone would say that. I spending all week testing here in Atlanta to see how it act. I drove the car with them just for a mile today and man it made the powerband more linear and killed the black exhaust. I checked the temps in the engine bay and they were below 100F, which is great :) Quote Link to comment
Lonestar Posted March 10, 2014 Report Share Posted March 10, 2014 Cool, about time someone did this. I see a lot of potential for building new parts for our hard to find for cars. I see you add tunnel fins in the horn, is this to improve air flow and such? Quote Link to comment

I place a burning piece of paper under the car to create smoke so I was able to see what the air was doing as it entered the carbs and it was very turbulent. With the fins added to the horns, it created a better flow into the carbs increasing atomization. This means a better burn, which means more power. (no claiming great number here, so don't kill me for saying that) . 1 Quote Link to comment
Just Joel Posted March 10, 2014 Report Share Posted March 10, 2014 I'll take a set shipped to 97702 please ;) make em 38mm Quote Link to comment
TENDRIL Posted March 10, 2014 Report Share Posted March 10, 2014 thats pretty cool man! Quote Link to comment
MantisX620 Posted March 10, 2014 Report Share Posted March 10, 2014 Can you make a set for R1 carbs? Quote Link to comment
RTB Posted March 10, 2014 Report Share Posted March 10, 2014 Someone needs to start CNCing these out of aluminum. Heat off my headers is my only concern. Great idea with the fins... You definitely should experiment a bit with pitch and size. Quote Link to comment
97_luder Posted March 10, 2014 Author Report Share Posted March 10, 2014 Can you make a set for R1 carbs? If I can get my hands on a set to get dimension, I can make a set for almost any carbs Quote Link to comment

You definitely should experiment a bit with pitch and size. That is my concern as well. But this was just for kicks and fun but it looks like I might be on to something. I will try a couple of variations on the fins, i might try grooves instead. Ill run simulations on the different designs I come up with. I am an engineer by so I can have these made here or overseas at a decent price, so lets see where this goes :) 1 Quote Link to comment
ggzilla Posted March 10, 2014 Report Share Posted March 10, 2014 Nice! How does the plastic hold up to under hood heat? Quote Link to comment
danfiveten Posted March 10, 2014 Report Share Posted March 10, 2014 Why i want to go to school for 3d printing, and then start making dash pieces and vents and stuff, be cool as heck to do. Quote Link to comment
RTB Posted March 10, 2014 Report Share Posted March 10, 2014 Groves may do better. You can borrow my Mikuni air horns for measurements if you want. Possibly a lot of small groves covering the entire inner surface. Edit- I would also flare out the horn more. At least thats the way my Mikunis are made. Quote Link to comment
97_luder Posted March 10, 2014 Author Report Share Posted March 10, 2014 Nice! How does the plastic hold up to under hood heat? Its holding pretty will. We should have decent weather this week. So I plan on taking it on a 70mph, 5 mile trip then letting the car sit in the drive way at idle for an hour and I will see how it acts. Quote Link to comment

I have a set of Mikunis off my 510. I think you might be right about the grooves, but the reason I didn't flare the horn that much was because it would create overhang and it requires supports to print that. But I will definitely flare it more if I plan to produce these of metal. Quote Link to comment
RTB Posted March 10, 2014 Report Share Posted March 10, 2014 I meant I have a set of mikuni air horns. Just clarifying. Edit- oops I did specify that in my OP Quote Link to comment

RTB Posted March 10, 2014 Report Share Posted March 10, 2014 Actually, if you lengthen the horn and get the air to cyclone early enough you could do a perforated inner horn surrounded by an outside horn. This would allow you to gain the HP with the cycled air + will act as a natural filter so socks are not required. Quote Link to comment
bonvo Posted March 10, 2014 Report Share Posted March 10, 2014 if all checks out you may want to consider selling these would be a cheaper alternative to the other ones on the market Quote Link to comment
RTB Posted March 10, 2014 Report Share Posted March 10, 2014 Sort of my inspiration. Quote Link to comment
97_luder Posted March 10, 2014 Author Report Share Posted March 10, 2014 Sort of my inspiration. my concern with this idea is that you will be pulling heated air from the header Quote Link to comment
RTB Posted March 10, 2014 Report Share Posted March 10, 2014 Well the only way that was my inspiration was the fact that it uses the centrifugal force created by air to filter out debris. Im saying that you could do something similar except horizontal. The reason it might be a good idea is because sock filters slightly reduce the venturi effect. Whereas using the centrifugal force created by the groove/fins to get rid of dust and other small debris might be a better solution for more horsepower. Quote Link to comment
datzenmike Posted March 10, 2014 Report Share Posted March 10, 2014 Not sure about those 'swirl inducers'. Quote Link to comment
Watson Posted March 10, 2014 Report Share Posted March 10, 2014 Great work! What type of plastic and what printer did you use? Quote Link to comment
