Porsche 944, 951, 968 L4: 2.5L 2479cc and 2.7L 2681cc
(both 78.9mm stroke as used in 944 variants); 3.0L 2990cc (88mm
stroke -- as used in 968, stroked version of scraper)
Customer request led to this
advanced composite scraper. It uses steel with
vibration absorbing doubling plates and a sandwiched polymer layer.
Only
$79.95
Teflon® stock and knife-edged versions $199.95; the Teflon® version
includes the rear screening found on the windage tray setup:
Windage tray setups: The windage trays have either the steel or Teflon
bladed upstroke scraper built into the framework. In addition, the windage
tray setups have a downstroke scraper that bolts onto the frame. The
downstroke scraper was originally used in the 928 windage tray setup and has
been adapted over. The 944/968 engine is derived from the 928 V8.
You must first determine whether you have what we term an "early" or "late"
style pan (968 and some earlier engines). There are a number of different
pans variations but for the windage tray it is the style of the internal ribs
that is important. The style of the internal ribs determines the screening
pattern used.
This is the "early" style:
This is the "late" style:
These two pictures of a previous "early" tray help to give you a sense of how
the windage tray works with the existing pan:
 
Here is a picture of a previous "late" tray sitting in a pan:
The current trays have removable screening that helps when fitting to the
engine.
Here is a series of pictures of a "late" style Teflon tray (the Teflon insert is
not yet installed):
  
$359.95 for the steel version; $459.95 for the Teflon bladed version.
We also make an oil pickup support bracket for the 944/951/968
engines that can be used with our products or by itself. The
customer uses the engine as a jig and the bracket can be brazed or
welded into place:

Windage tray setup. The kit includes the dual scraper as part
of the subframe. Ten socket head cap screws are included (12.9
grade -- same as factory fasteners, same torque should be used).
$329.95; Teflon version (below) available for $429.95.
Vaughan Scott, 924
owner and racer writes on 924.org:
"... I've been fine since installing the crank
scraper
and Accusump. I've even run races pushing 45 minutes without issue."
"Note that the design of the crank
scraper
(even the single one I have) fits up very close against the oil pan
on the "low" side. This acts then as a baffle to keep all the oil
from climbing up the side of the block on the LH turns..."
"... a report on the condition of my bearings, as I replaced my
piston rings yesterday, so was able to check them out. After 2 full
seasons of racing, the rod bearings look about like a 30kmi street
car - in excellent shape!"
July 2nd, 2008:
I installed my
944 Turbo Windage tray/Teflon crank scraper and I’m happy to
report my oil pressure is consistently 1 bar higher than
previously. Normally after working the engine at sustained high
rpms and coming back down to idle I would see the gauge
fluctuating above and below the 2 bar line. Now under the same
driving conditions using the exact same oil, I never see below 3
bar at idle. I just thought I’d share my experience with your
product.
Thank you,
Chris Jurkiewicz

The Porsche 944S Scraper and
Windage tray you made up for us WORKS GREAT!
The engine revs more freely
near the top and really pulls. It would actually labor at the
top end of the range before.
I wish we had a chance to hit
the Dyno but the performance I would say speaks for itself.

928 -V8
$938.95 Well tested windage control system for the wet sump;
currently the most complex aftermarket system in the world for any
engine. Part of the complexity comes from the customer being
able to follow the elaborate factory torque sequence on the numerous
bedplate fasteners; part of the complexity comes from the severity
of the windage problem itself. Like our other Porsche
products, the kit has been upgraded through many generations of
design.
The system is available for different stock and aftermarket strokes
and crankshafts. Please be sure to specify what engine you
have. if you are using aftermarket rods it is strongly
suggested that you use the Teflon bladed system.
It is also available in a modified form to be used with a dry sump
system. We will need to see pictures of the interior of the
dry sump pan in order to know what should be done.
Teflon bladed system $1038.95
Please contact us for pictures and/or fitment instructions.
Please be aware that these systems should be ordered well in advance
of fitment.
These systems are also available through our excellent distributor:
