BOV and boost pressure

[Audi-RS6-R]

Hey,

I would know from the RS6 drivers with more then 800hp how much boost pressure you are running and which BOVs you are using to hold the pressure?

Also interested in this and the location of them as if they are like the smaller Tfsi engine the diagram tears

They are located under the air boxes.. the valve sits directly in the air box almost like a "once piece" setup

[Audi-RS6-R]

So nobody?

Are all "over 800HP drivers" driving with the OEMs with no problems in holding pressure?

[Trups]

No issues with my 900 car. And I know it hasn't had an upgrade.

What's the issue with yours?

[Audi-RS6-R]

I had issues...no boost over 1.4bar - I have now 2 Forges mounted...and running 1.7 - 1.8 bar

I was just curious, how others driving with more boost and OEM BOVs

[rs6_sid]

does anyone know if they are a diagram style as at a guess they will degrade and would want changing if they are anything like other vag dv's

any part numbers ect ?

[Trups]

I'm going to book in for a map tweek soon so if your still unsure il be able to find out.

Will boost not go down to the turbo tho? Mine is the TTH 950. I'm sure I read before you had the TTh 850?

[TomRS]

If your running a smaller turbo you may require more boost then the larger turbo... all the cars (that i know of) running 900+ are on stock BOV's running around 1.2-1.4 bar no more.
I wonder if more can be had from the stock turbo's applying this principal? then again you'd just end up with a crap droopy power curve so probably not worth it.

apparently the stock turbos at 800ps are pretty naff compared to a TTe at 800+ the power curve is completely different.

[Audi-RS6-R]

Well - I am running the TTH850 upgrades with 1.7 @overboost

Yeah i'd have thought so too, they are small turbos and wont flow well higher up the RPM.

I'll be going down the 3" downpipe (no engine removal) and a remap from MRC just to push power a little bit higher but nothing crazy, it'll be a long while before i upgrade any further!

[rs6_sid]

I was keen on the downpipes as well Tom but I was a bit put off by the fact of one of the rear studs can snaps it's an engine or job if it does as its inaccessible !
