Rods through the exspansion chamber.

The middle exhaust mount is on the lower bend of the rear pipe. I have tried to spread the mount over a large area on the pipe so it will not crack.

------------------------------------------------------------

The expansion chamber with reinforcing cross pieces. The large sides on the chamber could resonate with the exhaust pulses and fracture the welds. I put pieces of 6mm rod across the chamber.

The engine bay.
Oil tank mounting.

This is the space in front of the engine. In this area I have the oil tank, oil filter, oil cooler and anti roll bar. The anti roll bar is only mocked up in this shot and will be a smaller diameter.
------------------------------------------------------------

The oil tank sits on the floor on a piece of rubber and is held in place by a curved bracket. As the tank is sat on the floor the weight is kept as low as possible.
-------------------------------------------------------------

Oil tank mounting.




Underside of the oil cooler.

The oil tank sits up to a curved plate on the chassis. There is another one further up the tank to support the top. The curved bracket is bolted to the floor.
---------------------------------------------------------

The oil cooler is a water / oil heat exchanger. This shows the underside with the brackets I bolted on so the unit could be bolted to the floor. Again weight is kept as low as possible.
------------------------------------------------------------



Porting the oil filter mounting.




Ported fitted.

The oil filter is mounted remotely on a housing. Just as you port a cylinder head for better flow I port everything where there is flow. In this case oil flows, so radius all the sharp corners to smooth the flow.
-------------------------------------------------------------

One of the fittings into the filter housing presented a sharp protruding edge so I chamfered it for better flow. The smoother the oil flow the less power required to pump the oil. This is attention to detail that costs nothing.
------------------------------------------------------------

Planning the airbox.

The picture shows the mock up of an air box for the induction. The original plan was for an air box bolted onto the injection units with a pipe down to an air filter in the front grill. But I was worried about vibration with an air box so far from the engine. I then realised that I had a ready made air box with the framework on the chassis. So I required a flexible seal between the air trumpets and chassis. Research on the Internet came up with bellows manufactures. I emailed drawings for a quote and have ordered some bellows which will be made to my spec.
