Pod Filter

[plasmid2]

G'day to all,

Against many forum members advice I went ahead and fitted a pod filter. It sounds awesome!!

Now... I know there is a thread somewhere here but I can't find it. At closed throttle why is there now a 'whooshing' sound? Everything else on the car is stock. Is this air going back through the pod filter into the atmosphere? What is the physics of it all? What is happening? I do love it though!!

Cheers.

First off, you better explain what you mean a bit better.

When my car is sitting with the throttle closed it doesn't make any wooshing noise at all.

What forum members gave you the advice not to use a pod filter and why?

If the wooshing sound your referring to is on throttle close after you've been on boost, then the noise will be the BOV venting air back into the intake side of the turbo piping. It will be noticably louder due to the minimal dampening from using a pod. If you've gotten rid of your airbox altogether and are just running a pod on the end of a pipe then that will be the reason you hear it louder now.

Physics?????

All it is is recirculated air that was once boosted but is now being bled off to the low pressure side of the turbo.

Proabaly cant find it cause your looking in the wrong section...try here where I moved it to, Fuel System & Induction Workshop...instead of where you posted it in the Blow Off Valve Workshop...

Sorry I should have explained better. All I have done is removed the factory air box and replaced it with a pod filter. So the pod sits in the engine bay. After doing some reading on the forum a lot members spoke about this not being the best set up as it will draw in hot air. Plus I believe pod filters are not street legal. So not any member in particular. Apologies for that.

What I meant about physics, was, what is actually happening within the system. I am only hearing the 'whooshing' sound when I accelerate hard than come off the throttle when driving. So coming off boost. As I come off the throttle, it is accompanied by the 'whooshing' sound.

Is the air I am hearing air back through the turbo? I didn't think it could be as there is a factory BOV. As the only thing I have changed is the filter set up (as I explained above) I thought it might be air venting back out the pod!!?? I was just making sure I wasn't doing any damage somehow.

What you have explained kind of makes sense though.

Cheers.

yeah mate the whoshing sound is the stock bov venting back into the intake when you come off boost. even just fitting an aftermarket panel filter will allow you to hear it more. basically more sound is escaping. no worries about it.
