I have seen the DIY Ram air where they go through the grill but i decided i wanted to make the best out of my Titek CF duct. VERY easy and straight forward.
I went to O'reilleys and bought a Spectre flex air tube made for this kinda thing for $20. im sure you could go to home depot or walmart and use the Dryer flex hose but the Spectre tube worked GREAT.

ok...Unlike titeks mounting instructs say, i used 4 torx screws to mount my duct on the bumper incase i wanted to remove it like so. i used small torx head screws so dougbt anyone would steal it. Anyways...

1: take the 3 clips out the bumper and that one side then remove your CF duct (if not riveted on. Makes for much easier tube install.)
2: after your duct is out remove your air filter (in my case its JWT) then slide your flext tube through the opening in the Radiator Support and start test fitting the Duct to the tube and bending it like you need to. (the flex tube may need to be trimmed in a area for the duct to sit back in prperly but no bigger just use some wire cutters)
3: once you have the tube in place and duct back in place all you have to do is drop the air filter back in and route the other end of tube to the tip of filter and DONE!

The Spectre flex tube hold shape Very well. i taped the tip of tube to duct sealing it off but it wouldnt move either way.
If you have any questions please ask. Get the most from your Titek duct.




Close up to see the tube.

 

hmm but are you really getting anything out of it :/, if not then what the point..... either way good way to think out of the box :0)

 

I take it you don't drive it on rainy days. Otherwise you got big ***** running that setup in LA.

 

well its ribbed and curved. and where the duct and tube meet its got a drop off so i doubt the rain would run up the tube around the curves and ribbs.

and at higher speeds the tube will def give gains

 

Just to be safe, the next couple of times you drive it in a good rain, I'd pop the hood and see if the filter is getting wet or not.

 

Ohhh this is not going to end will in the winter.

 

Why you say that? its no diff than the other ram air DIY's just using a titek duct

 

you really think itll get wet??? i didnt think it would. and IF it did it wouldnt drench it.

 

Your set up with a stock air box would be sweet.

 

Your giving water a direct line into the intake with your clothes dryer ducting. Maybe I'm being paranoid but I wouldn't run it without a bypass like my Nismo intake has.

 

And its not cheap dryer ducting. its made by spectre. i didnt go cheap. could it direct water? possibly. we will see later. ill keep a close eye on it.

Its so easy to put in. it could only be used for track days also. i can just bend the piping back on daily driving so its not all IN the filter, just moved back a lil

 

Think about it, at 60 mph you have a lot of air being forced into the duct. That could easily force water back up the tube. Unless there is a significant elevation change there's no resistance to the flow of water.

 

Even then, I would think that it is easier to suck air through the filter than it is to suck water. So, let's say the inner part of the filter gets wet, there is still the other 70% of the filter (the outer edges) that aren't connected to this intake that will remain dry. It may suck up a little bit of water, but I don't think it would be enough to do any harm because there is still so much area not affected by the water.

 

I don't understand why routing the tubing into the middle of the cone filter would improve airflow. Most of the air induction and surface area of the filter is on the sides.

 

sorry that your idea is getting shot down. But dont try to make a product you new wouldnt give you gains(the air duck) and then go and try to get gains out of it.

 

It's a good idea but I doubt gains would be measurable. That's why some CAIs don't show any measurable gain on the dyno. It's hard to make real-world comparisons.

Common sense tells you that colder outside air would have a more direct route to the filter area. The reality is that the temperature read from the MAF is usually only about 5º higher than ambient at 60 mph with the stock airbox. That's from observations taken with no consideration for calibration between the two so AFAIK the temps could be identical.

With this setup, he might be able to get the delta-T down to a degree or two. Is that going to make more HP - theoretically yes; is it measurable - no.

Neat idea but in rain-soaked LA it might not be worth the risk. A damp or wet air filter doesn't pass much air at all. If it starts sucking water droplets through the filter element and some impinge on the MAF the car is coming to a screeching halt.

 

check it out, i mean do what you will.. but i did the same thing and it does two things well... dramtically changes the airflow and the turbulence comming into the air box... and also sucks in MAJOR water.

Dude im with you, cool idea, done cheap etc.. but pull it off.. its not good for your engine. Just leave the open area from the vent.. and even that will wet your filter inthe rain, period.

The corrugation in the tube is bad for airflow, and i had it actually stall out on me a few times directly after a high rev..

it forces that air in there ( WHERE THE TUBE SITS) but all that forces air is still less than the total air youd get just having it all open.

I dont have the math done one this, but as i said, i did it too, and the car ran strange and my filkter was soaked on day one of even moderate sprinkling of desert rain.

The Z is a weird car. Especially w the airbox.. I had a JWT too.. I put the stock box back on and it runs MUCH better.

 

Hmmm im confused. There where multiple Ram air DIY's tht ran to the grill with cheap dryer ducting and everyone was so shocked and wanted to do it. but i do the same thing but through a Titek duct (what its actually meant to do) and get shot down..

I kinda see how it could confuse the MAF and to keep filter from getting wet i could just pull tube back and at least be sucking in cooler air. not as much heat soak. I dont know. but im not trying to make my idea sound good just not quite understanding how it could be bad for my car minus the rain drops (since i pulled the tube back away from filter, just bringing in cooler air now)

 

Ducting from the grill area up to the air box involves two 90º elbows and an elevation change. Water is a lot less likely to run "uphill" or be blown through two direction changes.

I think it's a nice implementation - but still have concerns because of our environment here, especially with a daily driven car. I'd consider it for track days or if I lived in AZ or CA where it never rains. Try it for a while and see what happens. Check it out regularly after driving in rain and see if the filter cone is getting wet. Use your own judgement as to when not to drive it in the rain.

 

im just gunna back the tube away from filter so its not shoving air in the filter just giving more cooler air, les heatsoak. yet still keeping an eye on dampness
