Ok just a quick update. Finally!!!
We have now got all the bits laser cut and I have welded up the cradles ready for powdercoat. The hard pipe upgrade is also ready for powder coat and will hopefully be getting done in the next couple of days.
So we are almost there.
My truck has been getting driven very hard and totally the wrong way for economy lately (I was trying to see what the fuel economy would get up to by flogging it) and the worst I have seen is 9.5l/100km (this is over a full tank not measured with a scan gauge)
We are yet to try a 3" exhaust either.
I have some dyno graphs here that indicate std power and power with intercooler and exhaust upgrade. Unfortuneatly due to poor labeling of the graphs it is a bit hard to get exaust only graphs but it will give an idea of the total gains possible anyway.
Notice the difference in power and torque at 1900 rpm. Almost 30kw increase and 2000newton torque gain. Also notice the fuel ratio graph leans out approximately 2 parts in areas which is a lot on a common rail car.
Overall they are quite impressive gains considering no extra fuel has been added and without doubt the vehicle will be able to maintain these figures for far longer under load than standard thanks to the effectiveness of the intercooler.
