So I went out and purchased an intake kit from Schucks for $76. I need to make it cooler tho.

Here's what I've come up with:
Getting a sheet of metal and bending it like seen here:

However, with my current setup (seen below) that would be hard to deal with, as far as getting the other hose in there to shoot into the airbox. So what I was thinking, was maybe creating an air diverter that is attached the the bottom of the hood. I saw one somewhere on a Mini last night, but can't find it again, as I came across it when I wasn't lookng for it.

Any ideas?

Thanks a lot!

 

Take a look at a MINI with an Alta intake or the like, in person, and then attept to bend your sheet metal accordingly.

 

Chya, good luck finding one of those in Boise, Idaho!

 

i see...in that case, shell out for the real thing (^_^)b

 

Just cause someone has a company label and I don't, doesn't make that big of a difference, except in price. I can do it. I just need to know what to do.

Is that so much to ask?

 

Hi, it's me again...
Before making too many plans, consider this: you are already half-way there. You left the bottom half of the original air box in place, right? Most of the aftermarket CAIs use that as a base for their shields, and the intake tube from the grille area already feeds into it. See? Not so bad. You just need an "L" or "U" shaped piece of sheetmetal to fit over all of that to create your heat shield. And some way to seal the shield to the hood (rubber weatherstripping works well). And don't forget to poke some holes in that firewall baffle, so your intake can pull in some fresh air. As a matter of fact, I have the rubber seal from the Alta laying in my garage (replaced with box top) that I would be glad to send to you. Also, reading through this how-to might give you some ideas:

So, all is not lost; you just have a little work ahead of you to make things work properly.

 

Lower air temp can be achieved by cutting a 2.5 inches diameter hole in the plastic shield going to the windshield vent. It will sound a bit louder (better for me) too.

 

I think maybe the air diverter you are referring to is DrPhil's FAD or Fresh Air Diverter...

...from his web page...

While its great to play Joe designer ( I do) - the reality is if you seal up your CAI properly to the hood and open up the back to the window vent you will get the most effective set-up. other things can be done to help but they are very small incremental gains. Are you in Idaho? If so I would have little concerns about your air temps. Come to Florida.

 

I opened up the grill and built a diverter to the OEM inlet portion on the radiatior shroud , also a heat shield from the air box "forward' (it just touches the ic horn), also big swiss chees mod on the sub fire wall.... now Ill find some photos and post.

I found this photo (Now running an aero grill, but did the same thing)
on the right side of the grill that is useally blocked off . I opend it up and you can see the duct that moves the air up


this photo the duct and heat shield can be seen

 

That looks like a nice setup, but I was told an airbox is the best way to go to reduce heat. Though I do like your setup. I almost got the Typhoon system but decided against it.

So here's the shoddy job my buddy came up with. I think it serves the purpose. It's not ugly, but it's pretty good for an evening of work. Tho there isn't that other hose going into there to provide more fresh air... It's a project.

COR: With that extra hose coming up and shooting onto your filter, do you notice anything different than if you don't have that hose shooting there?

 

Kudos to you for the DIY!


You might want to try sealing up the side that runs along the ECU and punching a few holes in the firewall behind the filter.

OR, try building a complete box.

I'd like to see how this turns out.

 

Thanks Russell. Or is it Cory? Heh.

Ya we spent some time on it and only ten bucks on the metal. We cleaned out my buddy's garage and found the tools we needed to make smoother cuts rather than the handsaw we used, so we might smooth it out later this week.

Now where exactly is the firewall? I know the vents behind the hood lead down into the engine bay, and I know there's a wall between the engine bay and the vents. But I also noticed there's a small (maybe 2") hole that leads from the factory airbox into the area between the engine bay and the cabin wall (firewall?). Maybe there's a guide on how to do this?

And I also thought about enclosing the ECU in the box also (as seen in the ALTA how-to install for the ALTA intake), but that was after we'd already bought the metal.

I'm pretty happy about it overall, and I think I felt a bit of a difference in the performance. I let the car warm up for about 10 minutes, then revved it to get some more heat in there, then took it out for a spin. Seemed more responsive around 2800rpm.

Thanks!

 

One thing that you will want to do is make sure that nothing is touching or rubbing. I see that your filter is touching the metal and it will rub causing wear on the filter. The same goes with the pipe going through the housing that you created. You will want that as tight as possible.

 

You are correct it's Russ! Having 3 first names confuses a lot of people, don't ever do that to your kids.

I misspoke last night it's not really the firewall it's the partition with the little hole in it. Randy from Webb Motorsports wrote up a bang up tutorial that may answer a lot of your questions here: https://www.northamericanmotoring.co...ead.php?t=4133

I also agree with the previous post, you probably want to get the box tighter around the intake's tubing.

Have fun tinkering!

 

Ya, we tried making it a round hole to fit the pipe snug, but like I said, we didn't know where the tools were before. Haha. But we found em, so we're prolly gonna do it again. We shall see.

That guide looks pretty good. I should use it. But when they show two pictures on top of each other, they're exactly the same picture so I dunno what that's supposed to do.

 

Remember uRabbit that heat gets into the airbox in 2 ways: directly by hot air entering the box, and via conduction through the box walls. The first method is prevented by sealing the box--you should look at where the metal box meets the original plastic bottom section. I notice yours isn't sealed there. Also around the intake tube. You have also removed the ram tube from the front grille, so make sure you seal the hole in the bottom box below the intake tube. This is also why you need a seal to the bonnet liner, or a box top to prevent engine heat from being sucked into the airbox.
The second source of heat is really a problem in normal street driving with stops and starts. Sitting idling at the lights just lets lots of engine heat rise and heat up the metal airbox. You should look into insulating it. THere's lots of threads on NAM about insulating the airbox.
Once you get motoring the rate of airflow in the box is so high that the air isn't going to get too heated by conduction.

 

Ya, insulation is another problem with my setup. The lines for the metal shield we made aren't very straight, thus creating gaps.

Is there any sort of how-to guide to creating the setup I'm trying to create. Like, telling the best method for bending the thick aluminum, sealing it, etc.? Time to start searching...

 

Well, there are lot's of threads, and trying not to self-promote, as I simply contributed my limited experience, but if you search for threads started by me, or with heavy contributions from me, you'll find over 90% of all the accumulated knowledge there is to find here on NAM.

 

This is going to be more expensive than having purchased the ALTA with the airbox... Sigh.

 

proabably

just add hood seal, open up the back and add back the stock air feed to the bottom of the stock CAI.

 

I can add a hood seal, if I knew exactly what you meant. Like the box top that you can get with the ALTA intake? I'm sure we could come up with something for that...

As far as feeding the snorkel hose in, that's a no-can-do. It doesn't fit around the intake hose we put in.

 

Hood seal is some type of rubber tubing that pushes against the bonnet to keep hot air from getting in. Basically you want some weather stripping along the top of your box to keep the engine air out.

 

Ah I've seen it. Hmm. I have no idea where to go for that...

 

I got some universal gasket from PepBoys. It's called weatherstrip for doors and bonnets, etc. It looks like an "O" on a "U" in cross section.
