Re: Air intake design & modifications


just thought id add a few points here,

from my experiences, there is no differense between a k&n pod filter and some of the other cheeper pods on the market. ill be doing a pod soon put using the standard piping and running tube from behind the grill to the front of the pod. I have done this in all my last cars with great success. Keep this in mind if you dont need a by pass valve.

remember also that in NSW it is illegal to have a pod filter, rta states that air filters need to be in an air box

Yes there is Matt, there are two type of set-ups, so let us be very clear and differentiate between the two:

1. Cold Air Intakes where the filter is located outside the engine bay and intake cold air.

2. Pod (also called short ram) set-up where the piping comes from the throttle body and ends in a pod filter type inside the engine bay. In this case sucking air from within the engine bay.

The difference between the K&N pod filters and other brands on the market is exactly the same difference between the K&N drop-in filter and other brands. Meaning filtration efficiency, airflow and durability.

That is one of many options to get cold air into your engine. After all it is a matter of running a pipe to the throttle body and have a good filter at the end of it. But you will need to find the correct size MAF adapter to complete the set-up and if you plan to use the existing filter box and have a pod filter connect to it through a pipe, there will be little benefit of doing so.

As I said earlier, the bypass valve is an added insurance and peace of mind.

Not entirely correct. The RTA states that pod filters need to be secure and enclosed to ensure you don't loose them on the road while in action. The way the filter is located in the CAI set-up in our case, is indeed enclosed and secured. Even if it falls off the pipe for one reason or another, it'll be trapped within the splash guard enclosure in the fender. It won't go anywhere.

The second RTA/ADR requirement is noise levels and am pretty sure that a pod/short ram set-up is louder than the CAI one. (someone can correct me if am wrong)

Re: Air intake design & modifications


There's even a third approach - - see pic.


Image

This approach is often referred to as a
Pop Charger - some are sold with heat shields attached...

Most of the ones I've seen have a home-made shield attached.

This is a pretty inexpensive way to go and there's no question that you're getting air pretty directly into the TB - - however, even with a heat shield, I suspect that it would still be quite hot....

So they're are really 3 after-market choices:

1. CAI
2. Short Ram Intake
3. Pop Charger

The backyard fabrications, using dryer tubing, ABS plastic pipe etc. all will work and I've seen some rather creative ones....

Some have the intake under the bumper - some passing thru the grill but that still leaves the issue of water ingestion...

If anyone is gonna fabricate a set-up, I think the "snorkel" is the
way to go emoticon

BTW - you can bet that this puppy is "loud"

Re: Air intake design & modifications


no need to get defensive! don't get me wrong, the set up u have is awesome I'm just saying there are easier options if you don't need the by pass.....

maf adapter wont be hard to get, i had one made for my sss for about $20


yep roger,thats what ill be doing with a duct pipe running to it as water is not a worry for me anymore. I have had this set up on all the performance cars ive owned, including turbo set ups and the heat isnt a problem if u duct it properly

Matt
This is the system I have had as well in the past I had my ram pod facing the front of the car and driled holes in the bumper and put mesh there to make it part of the car and it was cold air induction at its best and I had driven in the rain at high speeds in Atherton table lands it knows how to rain up there and this mod was on my Bluebird for over 200,000k's of its life and never a issue with water.

Wasn't getting defensive but was trying to explain the different options available. When you compare a pod set-up to the CAI and make comments in your post covering both is not entirely correct and things need to be put into perspective for the benefit of all readers who may not be familiar with the options and available systems.

Roger: The short ram and the picture you posted are exactly the same and it is what I was trying to describe. The air ingested in this case will be engine bay temperature and it far fro being ideal. Yes, the velocity of air coming through will increase, but the drawback will be hot air.

Similarly if one decides to enclose that filter within a heat shielded box, it will defeat the purpose of generating more airflow.

Just my opinion and everyone is free to choose a system to their liking and budget.

I knew you or someone else is gonna comment about the long hose, but I only left it there and used the one supplied with the kit cause am gonna be replacing it and the radiator hose with something flash soon emoticon



Roger, believe it or not but I have been trying to locate coloured silicone hoses and a braided radiator hose for the past week in Sydney and failed to find any emoticon

I never thought this type of hoses are hard to find, seeing that nearly every engine of many performance cars is decorated with them.

I just hope I don't have to import hoses from overseas LOL

Re: Air intake design & modifications


My previous car I had the air filter box chopped and exposed to the open air. I then replaced the filter with a K+N unit. The back end and bottom of the filter box was kept which somewhat shielded it directly from the engine but not completely.

I can say it was a huge improvement over taking air from the side fender, with most of the improvements in acceleration from standstill. Over time I did notice that the car suffered on hotter days, and in particular when I was stuck in traffic. I did get improvements when on the open road, and on cold nights, when the car just seemed to zoom like made.

I was planning to refit a full airbox again, but modify it for an intake pipe from the front of the car (similar to the X-Trail's setup) so I didn't have the side fender low pressure problems.

Based on these experiences, I would not fit a 'pod' type setup in the engine bay and draw in that hot air. If it was going to happen, I'd use a full heat shield, and to get the air flow, a scoop on the bonnet. Looking at it this way, you may as well modify the existing air box, connect a few more intake pipes to it, and increase the amount of air getting to the box. I'd imagine that the limitation wouldn't be on this end anymore, and you can look at other places on the car for flow limitations.

I know they are available but I don't know where, and I know they are very expensive! Years ago I enquired at a mechanical workshop (who tunes UniChip piggyback ECU's) in Belmore about custom-making an air intake for me using silicone hosing. I think the place was called "Rotor Sport" or "Rota Sport" - might be worth chasing them up...
