Description   Crankshaft Scraper for NON Knife Edged Cranks (all 2.5l and 2.7l) Fits - Porsche 924S All - Porsche 944 1983-1991 - Porsche 944S All - Porsche 944 Turbo 1986-1991 During normal engine operation a significant amount of oil adheres to or becomes entrained in a cloud surrounding the spinning bottom end.  This oil eats up horsepower your engine is making by increasing the rotating mass and also creating parasitic drag. A crank scraper mechanically strips off excess oil by coming close to, but not touching*, the moving crankshaft and rods.  It also interferes with the pressure differential that draws oil into the so-called windage cloud. These crank scrapers are constructed from 12 gauge mild steel (about .10” or 2.5mm thick) unless noted and include installation instructions. The scrapers are installed in a variety of positions but generally between the oil pan and engine block or along the main bearing caps.  Some fitting to your individual engine may be required and the procedure for carefully checking this is explained in the installation instructions. Do They Really Work?  Yes!  Crank scrapers in various forms have been in use for at least 40 years -- and not just in racing!  More importantly, they are currently in use in a variety of OEM engines of both large and small displacement -- from relatively low RPM V8 engines to high RPM straight fours.  Most auto enthusiasts are surprised to learn just how common they really are.  In short, it is an extremely well-proven technology that is often simply not recognized.  The modern trend is to have many more oil control devices in engines.  Crank scraper technology is OEM equipment on various modern engines from Nissan, BMW, DaimlerChrysler, Ford, Mazda, Honda, Toyota and many other manufacturers. Features **BENEFITS** Less rotating mass for the engine to accelerate because of the removed oil Less loss of power because of excessive drag caused by the windage cloud Helps reduce engine damaging oil-foaming Helps avoid oil starvation by keeping the oil in the pan during hard braking and turning as well as during off-road driving Helps to cool critical engine parts by quickly returning heated oil to the sump Helps to prevent the cylinder walls from being overloaded with oil Can help with fuel efficiency
