Re: Air intake design & modifications


Brett, you've obviously gone to considerable trouble to research this.
I have never recorded any temperatures but it has been obvious to 'the touch' that ambient air was entering the K&N pod I have fitted as I have previously posted.
This was further confirmed when I took my wife to Langhorne Creek for lunch last Wednesday. This involved mainly driving at 80km/h or 100km/h. On arrival I immediately checked the temperature of the airpod. It was as cold as the ambient (outside) air.
The air tube was as cold, virtually to the point where it clamps onto the throttle body.
I have blocked of the resonator by simply taping over it (wasn't that easy) and have made a small deflector to better direct the air coming out of the factor tubing into the lower airbox, up into the air-pod.
I agree with Sydo.
I find that once the motor starts to rev towards 3000rpm I have to throttle off under normal driving, as it seems to want to pull-ahead. I haven't encountered any flats spots throught the rev range and while the highest I have taken it to is 5000rpm it pulls these revs pretty freely.
I do however believe that Jalals setup has certain advantages. emoticon emoticon emoticon

When I lifted the bonnet last week (to install the radiator protection mesh) I noticed the muddy water stains in the front of the air intake following the creek crossing we did on the Murray Mouth Trip. This was with a water depth that didn't come up over the bonnet even with a bit of bow wave. So even the stock intake doesn't look too safe, especially if the water was even a few inches deeper.

Yeh Dave,

With Jamie having water up over his bonnet in one of the creek crossings he did on the Tag-Along tour last weekend, it would be interesting to have him see if there is any such signs of water getting in to his intake or maybe as far as his resonator emoticon

Hey Guys,
How does this look ?
Image Image Image Image

Last night I thought I might try and work out something to help to push some outside air into the stock intake while still hopefully keeping it relatively off-road "friendly".

I also found there are 3 resonators...
- small one on intake tube
- large one in wheel well
- medium one at back of filter box

I managed to tape over the holes for the large and medium resonators, and removed the white baffle piece from the bottom of the filter box to help get better direct airflow through the filter.

I'm interested to see if this has any effect.

Re: Air intake design & modifications


Kev,
 
What a top simple idea. Now please explain what you have used to make it. I can't really tell from your pics, but does the 'ramp' you used have an edging to force the air into the original intake and result in less air falling off the sides (just like a slippery dip, but in reverse...sort of ???)

As for the 3 resonators, I have only removed the large wheel well one and the intake one, but not the rear air filter one. Have you noticed any noise increase since removing all these. How easy is the air filter one to cut off.

Kev,

Great idea, I'm looking at doing something similar right at this very moment, however not as large as that emoticon

My first observation is that I hope you haven't cut off to much air getting to your radiator. emoticon

What I have in mind for myself is to just bring the alloy down to the first opening on the grill only which should not be much of a sacrifice for air flow to the radiator.

Re: Air intake design & modifications


Thanks guys.

Brett,
I made it from leftover tinplate sheet I had when I enlarged my letterbox recently. Easily found at any hardware.
Yes I have sides in the angled plate with a top lip slipped under the intake scoop to hold it at the top and a bottom lip slipped under the front bumper to hold it at the bottom. Needed simple cutouts to allow all fixing buttons to still fit through.
Here is the template.

Image Image

Started with the 300x300 sheet, then cut the 50x60 squares out of all 4 corners, then cut the diagonals for the foldup sides.
Test fitted to Exy for rough places for all button cutouts and finally cutoff clearance for bonnet catch.

Noel,
I would not imagine I have cutoff any more airflow than a large driving light would.
Infact, because the other side is still completely open as is the main bottom grille opening, I may have only cut off about 15% of the airflow at the most at a guess.

[Admin Edit]: Added alternative version of template with black writing on a white background for easy printing

Re: Air intake design & modifications


It might be a good idea, but may be dangerous to the motor in any water crossing. It would direct water from down lower directly into the air intake.

Haven't noticed any extra noise Brett.
The air filter resonator I just covered the hole with tape inside the air filter box.
A better way might be to plug the hole by gluing in a sink plug ?
It is easy to cut off completely if you remove the whole air filter box to get to the resonator from the back.

Thought about this too Dave.
Idea was to drill some holes along the top so that air would still be directed upward and the holes would allow the water to spill through if it got too high.

Anyway, creek crossings should always be done slow otherwise the bow-wave caused by any speed at all makes the height of the water worse than it really is.

Re: Air intake design & modifications


 Kev,
  Mate if I was you, I'd head down to my local solicitor and get this design patented. This idea is so simple and given the inadequate design of the current intake, may result in some good changes to the exy's performance. I can see quiet a few prototypes about to hit the forum soon, resulting in a little piece of aussie workmanship that does this forum proud. Top find mate and thanks for sharing it.

  I have already made 3 different templates to try and can't wait test them out. I am also trying to get a flow meter to see whether this increases the amount of air into the chamber or not.

  Although it has been suggested it may cause troubles with water crossings, it can be easily removed in 10sec. Simple and effective. Love it. emoticon
