air induction GOOD or BAD?

[ripp]

I spent about 4 hours couple of days ago reading posts regarding IK's and still not sure about them. I know maxogens have the best reputation, but they are pricey and to pay 400 on engine sound mainly is too much sometimes.
What I want is to clarify the benefits of the best ik's available, therefore I think we should bring arguments supported by clear facts such as dyno sheets, pictures of caf being mounted and full spec of the car with the ik mounted. what I want to see here is nothing else than clear evidence that the X product is good and Y is not as good. Personally I want to go for the BMC CDA, some said this kit is good, others claim it caused power loss. Those of you who had some rr done please post some pics with the caf's to see the way they were mounted beside the power graph.
Thanks a lot and I hope this thread will be a benefit for all

You're not going to gain any power. Some engine on other cars respond well.

I'd just get a panel filter and put the change towards a exhaust and a remap.

 

[ripp]

maybe it's harder to install properly on the clio, and easier on other cars. the space is limited for a proper caf fitment, maybe that's why it doesn't work so well on the clio's

Waste of time imo. Unless you want the noise which isnt all that special anyway. Save ur money and spend it elsewhere

it doesnt work so well becouse renault kno what they doing and set up there sports clio to get alot of power out of the block, so the CAf is in a tryed and tested location and the box is enclosed for good air flow, just the shape isnt the best, however a pannel filter is all thats worth doing imo, or a turbo, always a good alternative to a air filter, just a little pricy.

my guess is the only way it WILL work best is when the exhaust is improved with the airinlet-mod , for example v6 airbox, oem airbox with panelfilter, uprated bigger cafs , maxogen , etc.
and then a REMAP to suit the engine being able to get more in + out

The car is mapped from factory to get the best running taking in account environmental issues (very big part of the design!!) . So it runs at its best with the oem filter setup and i do'nt think the enginemanagement will know what to do with just an uprated filter mounted on there. It will just take the amount of air it was mapped to do so ?
When loosing cat , bigger exhaust+ better flow to go with this + improving airinlet, the car can be mapped to run a richer map with bigger/better combustion and forgetting about the environment but the car will GO

A Fastchip tuner kit (for example) is a pricefriendly map-mod where Henk can take in account your mods and tweak the map to suit your filter/exhaust etc. mods

I'm no expert but i think it works like this. Modern cars with computer-run engines are not so simple to tune with just the hardware

I am curious though if someone did actually gain something with a ik mounted on a stock clio. if not I will go for panel filter then exhaust+remap+IK

I would definately first go for what you stated here. Maybe also then trie to disconnect one of the cafs going to your airbox so it has that little extra air (so you can see benefit of larger cafs that you can maybe mount later)

Afterwards you can still go for an expensive airbox. Do a search , people on here make over 180hp with standard airboxes with uprated cafs (exhaust, remap already done!)

I think I've read all the threads regarding this ) I will probably go for better cafs and a panel filter first

 

[franx]

^^ way to go ! Wo'nt cost you much either !

 

[rob hope]

cafs? this may be a silly question but wat are they. i will probably kick myself when i find out wat it is but never mind

 

[172Ben]

cold air feeds

 

[rob hope]

yep i do feel a little silly now

this is the gospel.
Please can people use the search button, these IK threads are getting tiresome.

 

[ripp]

the idea was for people to post accurate data regarding performance gains or losses, not just "i've heard this, I think that" stuff.

 

[Tigger]

I have an intention of getting a more accurate RR result of my car as standard, and then again with my Maxogen & CAF
It will be in the new year though but it will kill a lot of curiousity and maybe settle a few silly arguements too;
Either way - it should be good fun finding out

^^^Will that represent road conditions though with the potential to be sucking in hot air with it being on the rollers? Even with the fans on its not like being on the road, maybe?


To do a true test between all the IK's and filters and decide whats the best i would have thought its the flow rate between entry (into the engine) and exit (from back of filter into the intake / TB track ) that folk want to be looking at.

Everything else like size, heat soak, position, has it been mapped, etc etc etc are all to do with the set up in the engine bay not ''how good'' the filter / IK actually is as a unit.

To back up this, many folk hate CDA's Vipers etc, but there's clear evidence that folk can get big BHP and very good track times with them in conjunction with other mods

 

[whatisjustis]

Good idea for a thread is this, so long as people stay on topic. It'll certainly put people's money where their mouths are...!

itg panel filter - 160bhp
Simota Aeroform - 161bhp

it's all much of a muchness and the only reason to get one is the noise. The amount of difference any of the filters will make won't be noticable on a day to day drive. I don't see why there are so many arguments over induction kits/heat soak/caf etc at the end of the day if you're only driving on a public road then the difference they make in performance is bugger all

Saying all that, would you spend 3k plus on engine work for example and have a s**t box stock filter stuck on the end of your intake?

 

[franx]

^^ one more thing i forgot when slating the Aeroform ;

Just watch your MPG go down the drain ! Now that WILL be important on the daily driver

Rhino; how has your car reacted fuelconsumption-wise ?

would you spend 3K on an engine for a road going car? i wouldn't...

I'm not saying there is no point in doing it for track/race cars as every little helps for the track but on the road the difference is very minimal between them all

no difference in fuel consumption since fitting the simota
