Air Filtration Test Disclaimer
DISCLAIMER: First of all you are probably wondering why this test needs a disclaimer. Well a few very loud individuals have proposed that this test is invalid as all variables are not controlled, for example the weather or the daily pollen count in the atmosphere. This is not a laboratory test, but a real world […]
Air Filter Filtration Test
Here is the heavily advertised K&N. Going in standard English (not Arab) book order (left to right etc.), next is the Amsoil air filter. (Click on images to enlarge.) After that is the Napa Gold paper air filter. On the bottom row are the Jackson Racing filter, Racing Beat air filter, and the Fram air […]
Air Filtration Test
This is a contribution from Anthony of our forum board. showing some interesting results on air filtration/ flow tests. I want to thank AnthonyS for all the great work in taking the time to perform these tests. Of course these are not standard ASTM tests and by no means represent any scientific certainty. He explains […]
Functions of Grease
A satisfactory grease for a given application must: Important characteristics a grease must have: thickeners commonly used in the formulation of greases Soap base: Non-soap base: Lithium soap base greases Lithium 12-hydroxysterate greases Lithium complex base greases Calcium soap base Relatively high thickener content of 10-15% by weight Smooth and buttery texture Dropping point up […]
What is Blow-by?
BLOW-BY occurs when the explosion that occurs in your engine’s combustion chamber causes fuel, air and moisture to be forced past the rings into the crankcase. Your engine’s rings must maintain an excellent fit in order to contain the pressure. The causes of blow-by: wear, soot and deposits As rings and cylinder liners wear away […]
Applications for Lubrication
Molybdenum Disulfide and it’s applications for lubrication The science of Molybdenum Disulfide is well established in the industrial community. Scientific and industrial literature describes Molybdenum Disulfide (MoS2) as a naturally occurring relatively inert, chemically stable, practically non-corrosive, non-toxic mineral commercially mined in Colorado, Idaho and South America. It is extracted from the ground, separated from […]
Moly Basics
Molybdenum Disulfide Molybdenum is a very hard metal with a number of industrial uses. It is combined with chromium in steel to make the steel harder and more resistant to bending. Most of the bicycle frames produced today use chromium and molybdenum steel. Because the steel is so much harder, the manufacturers can use less, […]
Effects of Shearing
How does an oil lose some of it’s viscosity in an engine? Shear stability is a measure of the amount of viscosity an oil may lose during operation. Oil experiences very high stresses in certain areas of the engine such as in the oil pump, cam shaft area , piston rings, and any other areas […]
