		<description><![CDATA[Tweet The other day I had a thought about DIY modifications, possible fuel savers and other performance tricks and tips to increase gas mileage. See, although this is a performance oriented blog, as the cost of oil per barrell crosses the 70 dollars per barrell threshold once again, and as the economic depression in the USA (and thus in many other parts of the world) seems to be very much a mainstay till around 2012 according to analysts, I can&#8217;t help but think about mileage and how so many people might want performance parts for their car, but they may also NEED better fuel mileage. This got me to thinking about how we as automtive enthusiasts modify our cars for increased volumetric effeciency and higher performance in a specific rpm range of around 4000 rpms and higher. This is mainly due to the fact, that when you are racing, you spend alot of your time on the eastern half of the tachometer in the higher end of the rev range and thus it makes sense that most performance products and tips are focused towards higher rpm effeciency. However, there are some (but not all) performance modifications (and racer&#8217;s secrets quite [...]

		<description><![CDATA[Tweet The whipple supercharger is a unique and very practical chager. The unit is a great compromize between a positive displacement supercharger (that creates boost pressure by over pumping and over feeding the engine with air) and a compressor (similar to a turbocharger) that compresses the air inside the supercharger housing before sending it out to the charger piping.    The secret to this style of &#8216;hybrid&#8217; blower is the two intermeshed rotors of different lobe numbers (see illustration). The combination of an intermeshed 3 lobe and 5 lobe rotor means that the rotors inside the housing are operating at different rpms with a ratio of 5:3 to keep the rotation of the lobes (3 lobes to 5) in synchronsim. This complex design allows the rotors to capture air (in its natural volume) from the back of the blower housing, and push it foward as the screws rotate. As the air is moved forward it is captured and compressed between the intermeshed rotors as well as being pumped (in positive displacement) from the inlet port at the back of the charger housing to the outlet port near the front.      Because of this unique design, screw style chargers are [...]
