BAFFLING
A ZEPHYR SUMP
By Karl
Schluter.
This is a plan of a baffled inline 4 or 6 sump. The
sheet insert is of the same gauge as the sump sheet metal.
The sheet separates the oil from climbing the sides
or front and back of the sump as to stop windage which is oil being hit by the
spinning crank. This costs HP, raises the oil temp, as well as mixes air with
the oil. I am featuring the above design as its less trouble and work than a
gated sump.
The oil holes in the sump baffle should be around
40mm in over all size. Do make a hole in the baffle for the factory dipstick
too. The oil level remains the same. The height of the baffle is not too
important as long as it clears the spinning crank, which it will if installed
as pictured and is above a full sump of oil. A section of the baffle needs
removed for the oil pump and pick up.
This baffle design is being used on Ford OHC
1600-2000cc engines plus others like Ford V8’s.
If you are handy the area below the baffle could be
enlarged to hold more oil and a boss for an oil temp gauge installed. Aim for
oil temps above 80 degrees as in my oil articles.
On my own car I also run a Moroso accumulator 2.
This is a remote oil reservoir that operates off the engines own oil pressure,
it supplies oil to the engine if the oil pump pick up is uncovered or a drop in
oil pressure happens for a short time. I also use mine to pre oil the engine if
it has been sitting for a length of time. This is better than any gated trap
door sump as it reacts quicker.
It can be plumbed in at the oil sender tapping in
the block.
For extra venting of a hi rpm engine I advise a twin
breather set up on the rocker cover and a vented catch can off the side plate.
Don’t install
a one-way valve to the headers or extractors to vent the rocker cover unless
you are running an unmuffled exhaust system, as they not designed to work with
any backpressure.
If running or interested in running a hose from the
side plate to the intake as in my PCV article, run a PCV valve to prevent a
sump fire in the event of a back fire. I also advise of some oil way and oil
pump mods in my hot engine build up article.
