Mmm, nice work.
Good to see some progress shots.
Is that a bigger tyre than before?
What is the scheduled completion time?
Nice work...
More info?? engine size etc etc?? those pics are just teasing us!!

tuff as nails.but. what is taking so long with this car,lack of funds or shit slow workmenship.it has been out for a while now..we would be keen as
punch to help out if needed,we want to see this car back in action.
wastegate pipe is proberly to small i hope that you are putting on a bigger one.
and why are your shocks so imbound the angle looks aliitle wrong,but in saying that its hard to tell from limited photos.
keep the pic's comong and for god sake hurry up.
Judging by these pics, it looks like its been to the track.....what times is it running?
Obviously it isn't finished being repaired after going on it's lid??
What happen to Pics , gone are they . Did Trent delete them .That was great vw porn !
has the first post gone?
yes stanley, gone back to secrets land
Guess someone got upset??
Should be good to see it out there again soon:

sorry
deleted both posts when trying to put pictures into same posts
some new photos , more on thursday if trent works on car
Yes Dave bigger tyre and time frame soon, as trent wants to get the car out , do some runs, then strip and paint.The last roll over was very costly.
Westi , the shocks are not mounted at the bottom, so wheel height could be set up on the jig to mount the guards
The wastegate is the correct size for a high boost motor. The car uses a co2 style boost controller designed by ron lummus, new to the car to control
boost better than the motec.
some new pictures, let me know if you want the last ones up again, sorry again
Looks fantastic. I like the grey will it still remain or have you a different colour in mind?
I also like the fact the volksy dash is still there in the background....
some more
Dash is to stay, colour ??? probably grey
Hot, hot, hot!!

CO2 boost control ... how does this work?? Sensor?
i pulled this of the net for you to under stand staley.
it pretty basic once you have read it and it makes good sense.
10x10
i under stand the co2 set up.but after making a fair few manifolds in my time pipe size and placement are also just as important as the choice of size
waste gate.and its flow.
i look forward to updates as the car will be nothing short of a masterpiece as always.
Co2 Boost Control: In order to understand why Co2 boost control is needed in some applications, basic knowledge of how a wastegate and boost
controller works is needed.
An external wastegate has a diaphragm which creates a seal, and a spring which holds the wastegate closed. Spring rates vary depending on the amount
of boost you want to run. Typically they are given in a "bar" value. For example, 1 bar would be 14.7psi. This would mean that in order to open
the wastegate you would need to exert a greater pressure than the 14.7 psi spring holding the wastegate closed. In order for the wastegate to work you
must have the boost reference port hooked up to the compressor side of the turbo or intake manifold. If you don't have this vacuum line attached
then the boost pressure will not be limited to the set spring pressure; it will build unlimited boost pressure until your engine is destroyed
(“bottom” wastegate port). Normally, exhaust manifold pressure pushes against the valve and diaphragm (through the vacuum line attached to the
compressor reference port) which in turn pushes against the wastegate spring. When the exhaust manifold pressure exceeds the spring pressure the
wastegate’s plunger opens releasing the excess pressure through the wastegate outlet (typically via a dumptube).
The top port on the wastegate is normally open to the atmosphere. This provides no additional resistance to the wastegate “spring”, and the
wastegate will operate at the desired spring pressure. In order to increase the amount of boost over the spring pressure inside the wastegate, two
methods can be used.
The first method is using a manual boost controller. A manual boost controller works using a spring and check ball. By screwing the adjusting screw
into the boost controller you put more pressure on the spring which reduces the amount of airflow through the boost controller and into the boost
controller port (“bottom” wastegate port). Less airflow means less pressure will be assisting the spring to keep the wastegate plunger shut. The
“top” port is left open to the atmosphere with a manual boost controller.
The second method is using an “electronic” type boost controller. An electronic boost controller uses a solenoid inline of the boost pressure
source to the top port on the wastegate. The solenoid is “pulsed” by a PWM (pulse width modulated) output from the boost controller or engine
management system. With more opening and closing of the solenoid more pressure is applied to the wastegate. With less opening and closing, less
manifold pressure is applied and less boost is achieved. When more boost pressure is applied to the top port of the wastegate, it directly applies
more force to the wastegate valve, keeping the valve shut until enough exhaust pressure is applied to open the wastegate. This is essentially like
adding a higher rated wastegate spring (stiffer). The bottom port of the wastegate is connected directly to the pressure source (compressor cover or
intake manifold), with nothing installed inline.
Exhaust pressure increases as boost pressure increases. The amount of exhaust pressure in the exhaust manifold is affected by the turbo exhaust wheel
size, exhaust housing size, exhaust manifold type (equal length or log), displacement, cam profiles, etc. In most situations using a manual boost
controller you are not able to increase boost much more than a 2:1 ratio, meaning if you are running a 10psi wastegate spring you are not able to
increase the boost much more than 20psi. With an equal length manifold, and large turbo sometimes a 3:1 ratio can be achieved. When using an
electronic boost solenoid on the top port of the wastegate, as much as 6:1 ratio can be achieved if an equal length manifold and large turbo are used.
For high boost applications, using a small wastegate spring for lower gear traction an electronic boost controller is what is necessary. For most
turbo set-ups (probably 95% of what is on the market) achieving a 6:1 ratio is not possible. This is where running a compressed gas that can apply
greater than manifold pressure is necessary. For example, a 3psi wastegate spring can be used, and flowing 90psi of co2 pressure to the top port of
the wastegate will allow for greater than a 6:1 ratio. This gives the ability to get the boost low enough to aid in traction, and increase boost to
pressures in excess of 50psi if needed. The boost solenoid vents the excess Co2 pressure so that target pressure can be reached. This also allows
for more boost consistency with elevation change, as you are not relying on less available atmospheric pressure for the turbo compressor to work with.
Boost controllers such as the AMS-1000 or AMS-500, and the AEM boost controller solenoid being used with the AEM EMS or Hondata systems are
compatible with Co2. It should be noted that Co2 as a pressure source is not practical for a daily driver, and should really only be used for drag
racing applications.
Westi, great summary and totally understand. Thanks.
Off topic and should be in another post called ASK WESTI!
I am running internal wastegate GT2871R and am doing the exhaust and muffler at the moment. Thing is I have looked at so many different exhaust
flanges and dont know whether to run a big exhaust or a splitter in between the wastegate and exhaust. I have heard this can cause pressure opening or
kreeping the gate open with the exhaust gasses sucking the gate open. Is this true, what is the best setup? My whole exhaust system is only 1.5 feet
long and using 2.5 inch pipe to keep the speed up.
Also on the subject of CO2, (Drag racing only) what is you setup your turbo completely seperate to the motor and spooled the exhaust turbine with CO2
and forget about the exhaust manifold and regulate it with soloniods? This would run cooler, get instant boost with no lag. Would this work?

Very well explained!!
Turbos are a fascinating little invention with a myriad of tricks up their sleeve.
This car was on a tow truck bout 2 months ago leaving city performance where was it going ??
