ok guys, after i did my little spurt of downtalking on cold air intakes on turbo cars, i wanted to create an intake system that will do what really needs to be done. the modshack intake is really nice as is the CDA BMC, but i wanted something better. i agree on 2 aspect of the intake. the round housing and the cold air feed. If you can provide the cold air then why not. I have a tt180 with a small k04 and all the other bolt ons. I've never been satisfied with intakes and wanted to design the following. an intake with a round housing that has a velocity tunnel at the filter right where it bolt on to the MAF. i plan on runnig a 2.75 or 3" maf and would make the intake for that. the velocity stack/ air horn is a 3" base with 6" filter opening. the horn tapers in from an outside of 6 to 3" which helps move the air a little better. the the horn would be about 1" from the base of the container/housing to allow the filter to mount and not disturb the flow. the filter will have a 6" opening and 5" top to allow the air to pass through nicely. the container inner dimensions would be 9-10" diameter by 10-12" length. and the outside would be 10"-11" diameter by 11-12" length. i want to create a thermos effect in the intake housing so the inside walls of the intake are totally shielded and separatedfrom the outside wall. that way the heat does not transfer too easily. the end of the housing would have a port to cold air. the housing will have to fit in the tt so dimensions will have to be adjusted by room. the turbo tubing will be wrapped in heat shied at discretion.
what do you guys think about this? i want to get real full cold air but mainly increase flow to the turbo. I am at the peak of my mods. i wont go past this point for a while as i'm happy with the power. the intake is the last mod i really want to put some design into.
give me some feedback if you can, and other suggestions.

 

so did you put the K04 in the 180?

 

[quote] this is an intake that i pieced together.its basically the same as the vflow and i spent like $130 for it.when i get some time im going to make a heatshield and then route some duct hosing to the front bumper and voila cold air.if you want more information let me know and i can give you several companies that sell the velocity stack.also my intake was a bit more expensive because i opted for the aem dryflow filter that is NOT cotton based, and instead just needs to be washed out with water no oil.

there are two companies that sell them.one of them is a black plastic wrinkle finish (and the cheaper one), but does the same job.however, the plastic unit does NOT come with the silicone adapter to attach to your maf.here is the link:

the second unit, which is the one pictured and the one i have is from
http://www.turbohoses.com
it is brushed aluminum and it comes with the silicone coupler in your choice of size and color.i got the 3" one.from there no matter which unit you go with, all you have to do is find out the size of the inlet on the velocity stack and purchase a filter that matches with that size.personally i wanted to try the aem filter because it never has to be oiled, and i figured it would be better for my maf after i had to clean the filter.any k&n will work, as well as any cheapo filter you can find at pepboys.the hose on turbohoses.com comes with a hose clamp and the filter SHOULD come with one as well.all you have to do is take a few screws out of your old airbox, put this one together, attach, and voila [quote/]

not mine but this should help.

 

Funny you should mention the thermos thing. I'm gonna try that sometime. Figured a double walled shell, pulled down to full vacuum. It might be a little heavy though, i dont know how thin I can go w/o the walls collapsing into each other. Stainless Steel, of course.

 

well. beasically what the picture shows with a shell around it. as far as vacum goes, i was going to use pexiglass with little rods supporting the intter wall all over the place. thermally plexi/ acrylicconducts less heat then metal and withstands high temps. i was going to also use some sort of thermal wrap on the outside, weight wont be too bad. its just manufacturing thats time consuming and costly. the deal is that i would possibly make more than one and sell a round for about 150 just to cover design costs. then not make any others. i'm not looking for profit, just braking even on design. these types of intakes usually got for a lot of money, and even then they dont cover every aspect of flow. i'll start a design soon and go from there let me know if there is any interest. i might make up to five. and also the materials are up in the air. i'm going to use the least heat conductive material i can get my hands on.

 

oh and yeah i have the k04 and did all the work on this car myself. the only time its been touched was for the giac program when i first got it. if you go under my profiele you can see some of the mods. the list is somewhat long and very similar to yours except its not a tt225

 

[hr]didnt see anything in your profile

 

TT180Q Super K04 w/inlet hose, 2.5" DP, forge tt225exhaust, FMIC w/2.5" over the engine pipes, forge DV relocated at TB, HKS EVC bc, fidanza flywheel ,spec stge 4 clutch, decon front adapter, hyperflex bushing front/rear, siemens 380's/ 4bar fpr, 2.75 and 3" maf housings(tuning still) motegi dpk 18's, Seidl body kit, has a tow hitch soon to be redesigned and tucked behind rear mesh. (use it for my cbr900)
has a boost guage and made some probes for air temps right after turbo and right at the throttle body. at the turbo i'm registering around 275 F under full boost at normal operating temps and after a 30-40min drive. at about 70F outside. at the throttlebody i'm seeing lower but i think my probe is bad. i'm expecting 120F or lower

 

275 f is why i know that cold air intakes dont really work on turbo cars. i put the filter under the hood and the temps are 275 had the injen CAI and it was only 2-5 degrees cooler. at the throttle body was basically the same.

 

when you say "super" you mean a ko4-2x (one of the 225 versions) or a direct swap ko4-001?
