Inlet / Exhaust System
The Inlet and Exhaust system are a part of an engine where you can gain or loose power simply because the engine cannot breathe properly.INLET SYSTEM
I fitted a Donaldson paper filter to the left
hand side inner wheel arch that fits between the firewall and the battery box.
The filter uses a primary filter element with a second safety element inside.
There is a 100 mm diameter elbow and hose connecting the filter to the specially
made inlet hat. I fitted a protective hood to the inlet of the filter.
LATER:
In an attempt to get cooler air, I removed the hood and turned the filter housing to point outwards towards the left hand bonnet edge.
After some time I found a Donaldson filter change indicator unit, which I fitted to the filter, it immediately showed a vacuum over what is recommended. After some investigation, I found that the filter could only flow 5.5 cubic meters, and that the engine wanted 9.5 at full revs, I then relocated the power steering reservoir, battery and radiator pressure tank, then fitted a second 6" unit identical to the first, now the engine smokes less and is more responsive.

EXHAUST SYSTEM
The exhaust system was designed and manufactured by TNT in Germiston. They built the RHS 4-2-1 branch in one piece and the LHS one was built in two pieces, two pipes in front of and two behind the engine mounting.
There are two 3" silencer boxes, one large
and flat under the belly and one tubular behind the LHS wheel.
All joints use flanges and gaskets and all bends are mandrel bent ie The tube
diameter never changes around the bends.
The system is very quiet, very firm and fits perfectly.
