Hi,
Sorry I know this subject has been thrashed out overtime here but I
just want to clear a few things up for myself. (must be a little
slow!?)
Anyway Installed my boost guage over the weekend, working well happy
with that.
Now I want to increase the boost a little as well. I've hunted out
and found a couple of good articles, the best appearing to be on
autospeed.com as to the Audi DIY boost control.
So just to be sure I have the application correct for the RS, I
wanted to clarify things. OK I would want to T the bleed valve into
the same line as the boost guage is T'ed off from. This is the line
that runs from the Manifold and I belive it goes to the boost control
solinoid?. I've seen mixed application some people have run this line
straight from the minifold to the turbo and the bleed valve used and
totally bypassing the solinoid, just capping its end. Which would
suit best?
Next I'd want to T a pressure relief valve into the line that runs
from the boost control solinoid to the wastegate.
Hope this is correct.
Last question is the conversion of 1 bar to PSI? I've heard the MAX
boost I'd want to run is 13psi, my guage is in Bar, and I've heard
mixed things as to the conversion from 1B=14.5psi to 16psi. any
comments would be great.
Thanks again.
Quin

AFAIK, 14.5PSI = 1BAR.

Boost Control
Restrictor's
Why use one? Well, if you don't use one, when you try to drop
pressure in a line you'll have to bleed out SO MUCH air that you'll
be hard pressed to make a large pressure drop in the line.
Where does the restrictor go? In between the source of pressure (like
the intake manifold) and the bleed hole (or bleed valve).
Restrictor Diagram http://groups.yahoo.com/group/BC-
BFLegacyWorks/files/restrictor.jpg
In the above illustration air molecules represented by dots are
leaving the intake manifold and heading for the actuator. Just as you
can make the actuator "see" less pressure than you're really running,
you can also make the MAP sensor see less pressure than you're
running. Same deal with the MAP line; orifice goes between the
pressure source and the bleed hole/valve.
You can use exactly the same style of setup for your MAP Sensor to
trick your computer into thinking you are running less boost.
Note: you also want to include a pressure switch in the circuit to
prevent overboost.

Boost Control
Dan,
Thanks for the reply, I was hopping for something like this.
The restrictor diagrame makes good sense, and shows this well. OK if
I understand you right I want a strictor between the Manifold and the
Bleed valve. I haven't got any of the bits I'll be needing so what
sort of a restrictor should I be looking for? Also as a side question
do you know of anywere I can get the bits I'll need in NZ?
My new enlitenment spurs on a few more questions. I am assuming that
in my cars current standard form I have a pipe running from the
Manifold to the MAP sensor, which inturn has feeding pipes from the
Turbo and wastegate. SO > I know I now need a restrictor to run in
line before the bleed vavle.
OK new revised plan, from line that runs from the minfold to the MAP
I want to have at the manifold end a restrictor and then at the MAP
end a bleed vavle? correct? I hope so. This I can manage and feel
confident to do.
Next what about a regulator before the wastegate?, so that I can
control how much pressure the wastegate see's before opening. So I
could set the regualtor to open once say 10psi has built up in that
line. So then I would avoid wastegate creep, so when boost comes on
it will come on hard.
Now next the bleed2 diagrame, this looses me a little, I can't tell
what I should be adding/re-plumping and what stays. So I am guessing
in this diagrame I would be totally bypassing the current MAP? and
effectivly making my own? IF my above plan would work and do the job
of increasing how fast boost comes on and how high it will bosst,
what will the sugestion in bleed2 do extra, I'm guessing be safer?
but not sure, I've just got the RS and am looking to keep it so of
course want the best option here as well, so all you ideas are really
very appreciated, so if you have chance to answer any of these
questions I would be very appreciative.
Thanks

Boost Control
Restrictor size should be about 10 to 12mm or .040" to .050", if they
are too small the check engine light may come on so just increase the
size.
Yes the second digram only refers to, from the manifold to the
wastegate actuator.
Mitre 10 should have that sort of thing or mechanical/engineering
workshop.
Please note your factory computer will not allow you to run above
14.7 psi unless of course you bleed the line to the map sensor.
You should be able to run 15 psi on the stock setup, more than that
and you will have to add more fuel.
Do not attempt any of this unless you have a boost gauge or air/fuel
mixture gauge.
If you have no air/fuel gauge, run a wire from your O2 sensor wire
(the one that reads .1V-.9V at warm idle, bouncing up and down)
through the firewall, into the car. Hook the O2 wire to the red probe
of a digital voltmeter; hook the black probe of the digital voltmeter
to a clean ground. When you floor it, you want to see .87V to .97V.
Less than .87V means you're not safely rich. Back off, and add fuel.
You can add fuel by raising the fuel pressure, adding an extra
injector, or switching to slightly larger injectors. If you don't add
any fuel, don't run high boost!

Boost Control
Dan,
Cool thanks again.
OK I'll hopefully be able to mass together all these bits and have a
crack at it this weekend.
So would you recommend bleeding the line to the MAP sensor?
I have a boost guage and have been running round with it for a week
or so and have a feel for current boost and want to run it upto 1
bar, so should be OK for stock.
Thanks for all your help.

I wouldn't change the MAP sensor line unless you are going to run
more gas.
