		<description><![CDATA[Tweet Here&#8217;s an interesting supercharger setup from MM&#38;FF magazine, with a great 305 performance build up: The 180hp 305 engine has been upgraded by: An Eagle / DSS / K1 stroker buildup brining engine displacement up to 347 cubic inches (5.7 liters). Holley Systemax high performance aluminum cylinder heads Holley systemax single plane intake manifold Kennedy&#8217;s Dynotune custom supercharger camshafts vortech J-Trim supercharger geared for a peak of 20psi of boost pressure A cog-tooth supercharger drive system to prevent belt slip and maintain peak boost at high rpms A custom methanol injection system to cool the intake charge The final result of this setup is a boost from 180 crank hp up to 660 rear wheel hp and a track-proven 9.70 @ 140 mph quarter mile time.

		<description><![CDATA[Tweet   Supercharger boost pressure controls how much additional horsepower your engine will make from using the supercharger. One of the simplest modifications that can increase supercharger performance is increasing the supercharger drive ratio to allow the supercharger to spin faster and move more air, thus creating more boost pressure. First an overview of the supercharger drive ratio. In a typically supercharger installation, the supercharger is driven by the engine&#8217;s serpentine pulley and belt system. Because the supercharger is connected to the crankshaft on the same belt, there is an obvious drive ratio between the supercharger and the engine based on the respective pulley sizes.    For example, if the crank pulley is 4&#8243; in diameter, then for every rotation of the motor the belt moves 2*pi*r which is about ~25 inches. If the supercharger had a snout pulley that were 2&#8243; in diameter, and there was NO BELT SLIP, then 25 inches of belt rotation will cause the supercharger to spin by 25/(2*pi*r) = 2 complete rotations. To simplify things, the supercharger drive ratio is exactly the ration between the diameter of the crank pulley to the supercharger pulley or in our example 4:2 which is 2:1.  It becomes [...]
