Oiling System The Vortech supercharger
is lubricated with oil from the engine. The head unit
is fed oil under pressure and it drains via gravity back
to the oil pan. This required two modifications. First
we need to tap into a pressurized oil source, and then
we need to modify the oil pan for the return line. We
detail these steps below.
The easiest place to obtain
pressurized oil for the supercharger is from the
oil pressure sending unit standoff. We drilled and
tapped it for a 1/8" NPT flare fitting.
We've got the supercharger
oil feed hose connected. The other hose is for our
Autometer mechanical oil pressure gauge.
The other end of the oil
feed line connects to this port on the head unit.
Do not substitute the Vortech fitting for a parts
store variety as it contains a restrictor to regulate
pressure.
Vortech provides a low quality
pneumatic hose (top). Ours leaked at both ends.
We had a hydraulic shop makes us this true high-pressure
oil line.
Since the oil pan had to be removed to be modified
we used the opportunity to upgrade to an 8 qt. Milodon
pan (PN: 30925). The added capacity will be of benefit
due to the heat generated from the additional horsepower.
Compared to the stock pan, the Milodon deep sump
pan has baffling for better oil control. The pan
is intended to be used with a custom Milodon pickup
tube (PN:18375). We also opted for a windage tray
(PN: 32210).
We drilled a 1/2" hole on the passenger side
of the oil pan. Place the hole between the first
two pan bolt holes and about 1 3/4" down.
We welded in a 3/8" NPT bung cut from an old
5.0L heater tube (because it was weldable steel.)
A standard 3/8" NPT hose fitting is threaded
into the bung. Alternatively you can weld in a piece
of pipe and clamp the return hose directly to it
or for a total pro job weld in a -AN bulk head fitting.
In hindsight we should have put a slight angle on
the bung to help the oil drain from the supercharger.
