Engine Bay Air Pipework

I have finished the engine bay pipework for the airbox => turbo => intercooler => intake manifold. The pipework is all 2" / 51mm diameter pipework, with the exception of a smaller diameter section pre-turbo since the intake of the turbo is only 40mm. I have used silicon hoses to join all the pipes together - all in BLACK as I 'm not a fan of blinged up engine bays. A series of 45 and 90 degree steel pipes were used, and it didn't take much time to mark, trim and tack/weld together all the pieces together. This is the airbox to turbo piece (fully welded) showing the silicon 51mm to 40mm reducer and 40mm pipework pre-turbo. I also had to reconsider the design of the upper radiator hose, as for some reason I had not thought about where the thermofan would sit in the original design. I used three pieces and joined them together with a small 50mm length of aluminium tubing and a sensor housing which will be used for a water temperature sensor. These will of cour

Radiator & Intercooler Mounting Brackets

This afternoons minor task was finishing mounting the radiator and intercooler. The bottom radiator mount has already been done http://mearcat.blogspot.com.au/2012/04/radiator-and-intercooler-fitting.html however I changed my mind in regards to the upper radiator mount and chose to mount a bracket to the top of radiator instead of the side. A simple (slightly bent) bracket with a rubber grommet was used to isolate any vibrations. Two blind nuts were also welded on underneath for bolting through the slam panel. I like to used blind nuts where possible as it's just easier to bolt things together! The intercooler also used grommets for vibration isolation and I used grommets on both parts of the bracket and the bolts were not torqued up much. The two parts of the bracket are not perfectly parallel - this is on purpose as I had to angle the intercooler slightly to clear the turbo outlet pipe.
