We've been talking to Kevin from www.crank-scrapers.com (http://www.crank-scrapers.com) about this fine product that he's been offering and have finally decided to start selling their Products. For those of you who have not seen this product before here is a write up straight from their site:
What are some of the 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
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.
Our crank scrapers are constructed from steel 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.
Our new Teflon® scrapers (patent pending) can safely contact rotating engine components. The closer you can run a scraper the more efficient it becomes. Typical safe clearances for standard scrapers run from .035" through .060" -- some more daring builders run them as close as .010" Teflon® scrapers can run in actual contact with the part, .000" clearance, but in reality the rotating assembly will bed or seat in the soft Teflon® and develop a running clearance of perhaps .001 to .005".
