Apexi Power Intake- Flutter!

[johnabs]

Hi,

Ive been hearing people saying that the Apexi Power Intake pod filter flutters and releases a wastegate type noise when u take ur leg off the throttle similar to a blow off valve. Is this true, as i currently have a K&N pod filter, and was wondering does the apexi flutter (eg. BOV or wategate pressure release).

Who has one, is it better performance wise or is it just all noise.

Cheers

John

wastegates do not make noises

there is no such thing was wastegate flutter

the noise you are likely hearing could be compressor surge, as a result of no or a very tight blow off valve

As above.

in no way what so ever will a pod filter make the flutter/venting noise. its all to do with the bov you have. all a pod kit does is eliminate the muffling effect that the stock box has and allows the sound made by your bov to resonate (echo). now some pods by different companies will affect the sound to varying degrees due to their differnt design, but they are all basically justa bit of shaped paper, foam or wiremesh on the end of a tube. just like the one you already have on your car

i have an apexi pod filter, and mine does not flutter. It has increased induction noise.

[LatinR33]

Apexi pods has a loud induction noise, basically amplifies the sound your car makes when u have the stock box and bov. If you car is fluttering get it checked because it can cause damage.

MY APEXI pod filter sounds like a tripple rotor

Since it's already been brought up, I've upgraded to a HKS 2535 but only on 10psi (for now)

I used to have the standard turno on 12psi and never had the flutter, just the load Pssshhhh,

Now with this turbo i get the flutter???? It's on the standard BOV. Only happens on full load between changes

Is the BOV reaching it's capacity?

I don't mind the noise but if it's gunna cause any damage, i'd like it sorted sooner than later.

Thanks guys.,.

I've just gotten my 2535 on too and have noticed something similar...only difference is that i have a rb20det and i'm using a standard gtr bov...any ideas people?

i got the apexi twin pods and when i back off the accelerator slowly it flutters (I think it sounds awesome too)

But the flutter isnt caused by the pods

[fr0st]

But the flutter isnt caused by the pods

But its a lot louder with the pod compared to the stock airbox which is designed to keep induction noise to a minimum

[tek_01]

i had a very slight fluttering noise when i put my pod on when i back off the throttle gently but as soon as i installed my fround mount geez it flutters like crazy. it must be echoing off the intercooler pipes and gets heard through the pod im guessing?

for the guy with the 2535, you just need to adjust your bov, although your running the same boost, the 2535 will be feeding your motor cooler air, so there will physically be more air in the system, hence its fluttering now, same goes for you tek 01 with a front mount theres alot more air in there still when you back off, so thats why it will flutter now, just need to adjust your bov

[tek_01]

tighten or loosen?

[PH34R]

loosen mate, so the bov will release it earlyer

what he said ^ let the spring tension out a bit so it can open easier/longer. as a basic rule, set it so it closes just before it gets to idle

the noise is always present and is amplified by the pod type, i dont run bovs at all and get crazy (dose, flutter and whateva) intake reverb noise on the rb26 and the SR20. BOV's can alter this noise but again have nothing to do with the cause.....only the effect

no ppl that^^ is not an invitation for a bov debate lol

[O.I.C Napster]

Well it seems like alot of ppl have the flutter with POD's etc. Well i have a front mount with CAI, pod and a stock BOV and i cant seem to get any flutter!!!! Any one tell me why not?????? (just a big woosh) HELP
