johnabs Posted March 25, 2007 Share Posted March 25, 2007 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.

paulr33 Posted March 25, 2007 Share Posted March 25, 2007 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 Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3004992 Share on other sites More sharing options...

Basti Posted March 25, 2007 Share Posted March 25, 2007 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 Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3005024 Share on other sites More sharing options...
Guest intouch Posted March 25, 2007 Share Posted March 25, 2007 i have an apexi pod filter, and mine does not flutter. It has increased induction noise.

LatinR33 Posted March 25, 2007 Share Posted March 25, 2007 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.

Guilt-Toy Posted March 25, 2007 Share Posted March 25, 2007 MY APEXI pod filter sounds like a tripple rotor Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3005482 Share on other sites More sharing options...
Birnie Posted March 25, 2007 Share Posted March 25, 2007 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.,. Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3005500 Share on other sites More sharing options...

R31Nismoid Posted March 26, 2007 Share Posted March 26, 2007 But the flutter isnt caused by the pods Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3005965 Share on other sites More sharing options...
fr0st Posted March 26, 2007 Share Posted March 26, 2007 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 Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3006049 Share on other sites More sharing options...
tek_01 Posted March 26, 2007 Share Posted March 26, 2007 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?

VB- Posted March 26, 2007 Share Posted March 26, 2007 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 Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3006473 Share on other sites More sharing options...

VB- Posted March 26, 2007 Share Posted March 26, 2007 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 Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3006911 Share on other sites More sharing options...

BOV's can alter this noise but again have nothing to do with the cause.....only the effect Edited March 26, 2007 by URAS Link to comment https://www.sau.com.au/forums/topic/161823-apexi-power-intake-flutter/#findComment-3006914 Share on other sites More sharing options...
