Added Cold Air Box Now Car Feels Slower

[r33madd]

Hey guys

Not sure if its just me

But i added a Cold air box to my car on the weekend and my can now feels like it has less power than it did without it.

has anyone else come accross this before

how can i find out if the air box is not doing the car any good without getting on a dyno.

Cheers

Man thats wierd!!! The cold air box should not make you lose any power. Are giving it a proper Air feed??? What kind of air box r u using?? by the way I think your cars hot!!!

thanks dude

Maybe its just me i dont know but something dosnt feel right. maybe a ecu reset may be a good idea.

as for an air feed i dont really have one there it just the hole where the factory pipe use to be which im yet to Duct.

well theres your problem... if you had the snorkel before, and then took it off and didnt do the CAI properly, you wont be getting cold air... you will see a dip in performance...

do the CAI and it should be a lot better

[r33madd]

I was ment to say where the factory intercooler pipe use to be.

The hole under the air filter.

The factory snorkel and airbox is long gone

I have a HKS pod filter and a CAI that encloses the pod filter in the corner.

Hmmm weird...

What sort of airbox enclosure do you have man? Make sure its not enclosed too much otherwise you might not be getting as much air as you need to. Try ducting it and see if that helps; all you need is to put some piping from where the side mount used to be into your airbox (im sure plenty others on the forums have done it before).

Unless its a major drop in power it shouldnt be an ECU problem. Try getting some good air to it first.

Cheers buddy

leaving the hole in the bottom should be fine. I'd check your piping.. sounds like you might have a leak.

pics?

[DRD-00F]

just cause you have a box around a pod filter doesn't make it cold air induction...

are you saying you have a new pipe pulling in cold air that goes through the factory intercooler piping hole? or have you not done that yet?

[LatinR33]

An ecu reset is always a good idea. Im thinking it is to do with air feed. Maybe take the box off and see if your car goes back to normal. If it does then its an issue of not enough air. Did the car run well without a box or was it suffering from heatsoak???

[r33madd]

I do not have the Ducting in the factory hole Yet but im going to.

Car ran well with out the box but people kept say you should box that pod in car will go better haha so i did.

maybe heat is getting into the box and not getting out so it is making the box act like a pod heater not a cold air box.

ill check for major gaps and add the ducting and reset the ECU

Then will get back to you all with some pictures.

but mean wile im still keen for other peoples ideas

[LatinR33]

Whats surprising is that if its like one of the UAS type cold air boxes these are well sealed and the air is picked from behind the headlight. so wierd that your not getting air.

[Strik3r]

i cant imagine the heat buildup getting worse for installing a shield around the POD.. even without proper ducting, just having a hole at the bottom of the box to draw air in from behind/below the headlight (as mentioned above), should see an improvement. therefore it sounds like somethings gone wrong in the installation. check all piping, make sure POD was reinstalled correctly. maybe clean out POD if it was removed and put somewhere where it could have gotten dirty/blocked.

are you sure it's slower or are you going by the lack of induction sound?

also, do you have the option of going back to factory airbox and intake?

[BAMR33]

CAI's are a waste of time, especially when you have a large front mount. They just confine the amount of air the engine can suck in.

When you're traveling along at speed it's not like the hot air from around the turbo is going to travel backwards towards the air intake...

[r33madd]

na induction noise is still pretty loud

one thing I should add is I also put my Exhaust Silencer back in the same day that could help with playing mind games I guess.

Agreed. You don't get heatsoak when your driving. Exposed pod with cold air routing FTW. Oh wait, except if your not in QLD it's probably illegal to have an exposed pod.....muahaha. QLD FTW.

Your silencer robs you of power. It restricts your exhaust. Restricted exhaust = less power.

Yeah take the silencer off thats probs your dilemna. you wont get heatsoak while driving especially with that massive cooler. Heatsoak would occur when your at traffic lights on a hot day and you'll feel loss of power upon take off.

that's your answer!

Exactly x 2, with the exhaust silencer you restrict so much air flow and create a lot of back pressure just take it off and you notice the power back up again, it might also help if you finished off the air ducting from your front bar to the stock intercooler hole so there is more airflow into the airbox.
