Increasing Turbo Sound

yeh any intake kit using an exposed filter element will make the oem bovs alot more audible

the greddy kit is quite good, but anytime you change the length of the intake filter vs position of the maf over stock you will need to re-tune for it imo

im running the top secret intake which places the filters in the same location as oem

an even cheaper option would be grabbing a set of gfb bov's

However the Greddy suction pipe is built so there are no additional tuning necessary. We have cars running these without a COBB AP.

Thank you guys! Thanks Eugene for the info. I've been meaning to visit SP for a while now (we spoke on the phone recently-my name is Sergio). How much does the Greddy system run? I really want to hear the spool up and suction of the Turbos....extra BOV noise would be awesome too! I'm trying to avoid installing the Cobb AP for no other reason other than voiding warranty. I really love the unit but can't justify losing the warranty potentially.

intake or bovs will void warranty too

Damn, Really? These mods do absolutely nothing to our cars really.

It depends on the dealer and their interpretation but I can return my car to original form with physical parts if something goes wrong. On the other hand, a Cobb reflash will appear in an electronic form which I can't return back to stock.

just un-install the AP and it will go back to stock .. that why i did ..

Yeah but if something goes wrong they can check your ECU for what boost levels the car has seen throughout its lifetime. They can tell from your peak boost numbers if you ever had the car tuned.

Yes that's what I know also. The GTR creates a memory for certain sensors and parameters much like the "black" box in an aircraft. I heard they can even check more than just peak boost levels such as if the ECU settings have been modified.

The turbo's on this car are quiet, my pops cl550 has a much more noticeable turbo sound.

Intake helps, but you get more of a bov sound than a turbo whine.

More turbo whine? You could get a set of poorly balanced turbos...it's the slight imbalance in the turbine/compressor system that makes the whine.
Ballbearing turbos hardly whine at all; standard journal bearing turbos do it much more, and with a poor balance, you are in Turbo Whine Heaven...but your turbos are in Turbo Whine Hell

Turbo "whine" is not what I'm looking for in sound. I want the acceleration of the suction air into the turbos to be heard. In other words I want to hear the "whooshing" sound of the air entering the turbos. I think an aftermarket intake system is what I need.

yes thats all you need to suck more. make more sucking noise.
I run 3" and sucks hard.

How would replacing BOV void warranty?

I'm pretty sure they don't.

is there proof, that they can detect over boost. I have a tuned fbo 335i and people thought the same thing before for that but its not true.

Anyone have any experience with or seen first hand the AAM 2.75" intake system?

Does anyone know would custom 76mm intake, custom ic piping kit and GFB bov make any difference to the Greddy kit?
