Hi Guys,

My mates at Castle Hill Exhaust had my jeep today and have made a custom air intake.

I am going to be driving with it on my car for a week, at which time, if there are no issues it will be coming back off, and it will be used as a template, so more can be made.

The filter sits down the bottom of the engine bay, underneath the chassis rail, and obviously has a custom alloy pipe up to the TB.

Unlike the Bwoody, we have left the original washer bottle in, which means there are no mods needed to fit the air intake, However due to still running the stock washer bottle the largest tube we can get through is 3.5".

After doing 60km tonight, this is what I have found so far,
Whilst moving the IAT's are 6-7 degrees C hotter than ambient temperature.
Once stationary in traffic, the IAT does go up, however the minute you start moving again, it drops straight back to 6-7 above ambient.

Next note, the throttle is more responsive and the gearbox in normal mode is a lot smoother, probably because you are driving with less throttle percentage.

I will keep you all update, and let you know once we have them ready to go.

Expected price is likely to be between $350-400 dollars AUD.


Hope this might help a few of us here in AUS / SYD.

Have fun

Marc

Hey Guys

Sorry for not getting back to you with any update,

My father went into hospital early last week, and all my time has been down there.

I will catch the boys at CHE this afternoon and see where we are up too.

Will post later tonight once home from visiting,.

Thanks

Marc

Not wanting to steal Marc's thunder but I could not help myself and gave CHE a call, who told me:
- Road testing was fine
- Expect to some Dyno tests etc next week then they expect the are right to go
- They said to keep an eye on this thread for more details

I'm a newbie to perf mods and asked about hydro issues with low CAI designs like this and they said "Common Sense" to avoid issues..... but "Common Sense" is not so common at time! (well for me). I take it there are some obvious stuff like don't try to drive through rivers but what is the real risk of such low CAI designs and how can you minimise this risk?

Here in Syd we get the occasional heavy downpours with some local road "flooding" (more large puddles), so how do you avoid issues or am I over thinking the potential issue?

Thanks

Nathan...avoid all that by installing a filter wrap or dry charger. K&N sells them and many others. they let air in...but keep water and dust particles OUT.

Hi All,

Sorry, been way to busy lately between home and work.

Intake jig has been made, and i believe that there is a car getting one today as well.
So basically ready to be ordered from CHE.
Anyone interested, just let me know and i can pass on their details.

Sorry, first time on the forums in over 5 weeks.

Thanks for the update Marc and I hope your father is well. Do we have any idea on pricing and if they can ship to the US? PM me if needed...

Just spoke with CHE,
- AUD$800 for a custom tune & dyno work (I already have Diablo so saves some $)
- AUD$600 for the CAI and Install

Mmmm, so $1,400 for this or $10K+ for the Ripp Supercharger (by the time it is installed, certified etc)..... Chalk and Cheese I know but decisions decisions....

Im keen to see the numbers on that Cherry Red one....
mine will be going in there next week (aslong as dealer keep there due date)

Its made 318 AWKW so far and if you pop the lid on the air box it does 325awkw.

So with a tweak to the tune we are all thinking it should do around 330 AWKW.

Don't forget it only has stock headers and cats too, so probably some more KW hiding in there and then its only on 6psi too.

All in all its a pretty good package!

Hey Rob,

Mate, alive yes, wasn't well for a while, did my back in big time and still have Physio 3 times a week now, but hey, thats life.
I will have to ask the boys what they are asking for the intake.
I will probably pop past there this arvo, so will post it up later.

I'm on my way to Toowoomba on Thursday in mine, so going to be interesting to see what fuel consumption i get LOL. PS Mine has an average of 21-22 round town, so i have never babied it yet hahahahahah

Have fun

Hey Mate,

Yeah, my average for the 8500km the car has on it is 21 so LOL.

My commute to work though is relatively short and it only rarely sees the freeways and normally when it does it has a trailer behind it.

Does still beat most P platers though with 2.2 t behind it LOL

Have fun.

Few Pics from CHE. Need to see pics uninstalled and of how the CAI is routed down to the front bumper area for true cold air.
