if you are lucky, and you can find someone that does not know what he is holding in his hands, you get them for about R1500.00....
ok my finding with the map properly altered for the boost coming in much earlier.... it's an absolute beast low down, boost is absolutely there when you need it,
effective rev range....: 2000~6500 rpms with the distinct difference that the full amount of boost is immediately available at any point in that range... amazing!
I have reservations about it's lung-capacity, though it was not surprising, looking at the compressors physical size, it was to be expected, this one at A\R-0.42 will run out of breath.
nun the less, with the considerable amount of gained torque way low down, this is a more than advantageous compromise for a car that is to be streetable.
I think, with slight alterations to the sizing of the compressor side on this one, it will be able to give enough air at higher up RPM ranges as well. making it even better.
one also need to keep in mind, these are not meant to be full out extreme turbos, EGT's will damage the geometry altering device in the turbine.
things that I can now still tinker with... VVT timing in corelation to where VGT starts to change....
Methanol injection and quantities in relation to VGT...

Is this on the 4aget bakkie? What turbo are you comparing it to? 15k is too steep. A ballbearing turbo cost less

yes it's on my 1400 which had a T25 on before.... can you imagine... a VNT ball-bearing turbo. Boost without even having the engine running....

not much... the problem is the veins need to be controlled and the vacuum actuation is not good enough... I'm busy trying to figure out how to get the electronic actuator to respond, but no luck on that front yet .. ether... http://www.google.co.za/imgres?imgurl=h ... s%3Disch:1

I have one of these on my Ford Mondeo Estate here in the UK. It is also controlled by a solonoid. What I can tell you is that when the car idles the vacuum of the motor pulls the actuator arm on the exhaust housing closed. Closing the veins. At a certain rpm the solnoid closes, but doesnt block the actuator if you know what I mean? that way the actuaror gets no pressure, and releases to open the veins. Will draw a picture later. You can easily make the gotech send a signal at a certain rpm cant you? You will just need a Y piece solonoid. If the turbo has nothing connected to it, its standard position is with the veins open!

But some of the Ford Mondeos have electric ones like you have there
