Forge DV with BMS DCI?

16M4 · 10-22-2010, 03:21 PM

Anyone have a video clip of their 335 with Forge diverter valves and BMS DCI? I'd like to hear the sound of it. I plan on getting Forge DV's but kind of affraid that they may be too loud.

How are they compare to the Tial BOV (sound wise)?

Im pretty sure Forge DV's are very quiet, but it all depends on your boost levels. I am also interested in hearing them, I cant really find any good videos on youtube.

TialBOV is pretty quiet, but louder than the forge DV. The forge DV are not intrusive at all and sound pretty good

I would assume so. But, I just want to be sure that they are not going to be super loud with the DCI

They are Diverter Valves, they make zero noise. You realize they aren't sending the air to the atmosphere like a bov? They re-circulate the air back towards the turbo inlets. Mine make no noise at all. To be honest, you do DP's and then you will have some noise!

I'm almost sure that they will make some noise if you don't have the stock air box. My forge diverter valve made some noise on my TT.

Your really not going to hear Anything with diverted valves.

Even the stock DVs make noise. It's more pronounced with DCI and running a lot of boost. When you let off the throttle, you'll hear a slight whoosh. If you drive with the cowl off, you'll hear it a lot more. Sensitive hearing also helps.

I have forge DV with BMS DCI... it makes some noise, but i don't really like it. I will record a short clip for you later tonight....

kang159 · 10-23-2010, 06:00 AM

forge DV with BMS DCI definitely makes a whoosh..but definitely quieter than BOV...i feel like i hear it more with the windows up...I've never heard what it sounds like from the outside...

That is true. I hear more and more each day I drive my car.

I hear more whoosh sound louder and louder everytime I drive my car and that I feel my car is not holding boost after 4-5K RPM. That's why I want to get Forge DV's thinking my stock ones are not good anymore.

The tial is much louder?

bulldog_yyc · 10-23-2010, 09:49 AM

tial is one of the quietest bovs on the market but its definately still a bov. If I were to compare, the DV's have a lower toned whoosh sound and the tial bov a slightly louder psshhhtt sound - sorry not very scientific but you can search for videos on youtube to compare the sound.

It's a PROcede feature. Fuel gauge = boost gauge; Oil temperature gauge = AFR.

DVs + DCI don't make any BOV type noise. The only thing you'll hear is the suction noise from the DCI.

If you listen carefully in the vid you can hear the slight whoosh, I have the forge DV's and although not as loud as a BOV when the DV's release the air to recirculate you can hear it.
