The increasing popularity of track days and other such events coupled
with the search for ever higher bhp figures has highlighted some
alarming shortfalls in the standard sump fitted to the Impreza from the
factory.
As most are aware the sump pan carries out a vital role in any engine
collecting and storing the engine oil before being distributed around
the engine lubricating and cooling as it goes. Shortfalls in the
standard sump arise when the cars are used on track where oil surge when
hard cornering soon becomes a major problem. In simple terms oil surge
is a result of the lateral forces being exerted on the oil pushing it to
one side within the sump pan. The central positioning of the Imprezas
oil pick up pipe can mean that under these conditions the pick up pipe
can become starved of oil often resulting in a major engine failure as
the engine loses oil pressure placing extreme pressure on the bottom end
components.
Starting life as a genuine Subaru oil pan to ensure perfect fitment
the baffled sump is then re engineered removing much of the
relatively ineffective standard internal shelving system and is then re
manufactured to accept our specially designed removable Group N alloy
baffle insert. This insert incorporates x4 heat and oil resistant
nitrile one way valve flaps to keep the oil exactly where it needs to be
even under hard cornering on track or during competition use. The
baffled sump kit also features an additional -8 boss for easy plumbing
in of a return to sump hose from an oil catch tank system. Supplied
with full installation
instructions , x14 genuine Subaru sump bolts and titanium magnetic sump
plugs all pre-lock wired and ready to go!
