Vortech is better than Eaton. I read it so it must be true.

Actually, now that I think about it, it said Eaton is better than Vortech.

Wait or did it say Pro Charger was better???

Try This, if the motor had enough balls it wouldn't need a S/C.

That should do it......5.4.3.2.1 :burnout:

Still holds.

I wonder if we would put a supercharger on a Cadillac, the engine could still hold together ?

That one should do it (!!)

From Wikipedia, the free encyclopedia.

Godwin's law (also Godwin's rule of Nazi analogies) is an adage in Internet culture that was originated by Mike Godwin in 1990. The law states that:

As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one.

There is a tradition in many Usenet newsgroups that once such a comparison is made, the thread is over, and whoever mentioned the Nazis has automatically lost whatever argument was in progress. In addition, whoever points out that Godwin's law applies to the thread is also considered to have "lost" the battle, as it is considered poor form to invoke the law explicitly. Godwin's law thus practically guarantees the existence of an upper bound on thread length in those groups. Many people understand Godwin's law to mean this, although (as is clear from the statement of the law above) this is not the original formulation.

I bought tickets for both of the supercharger raffles.... didn't win on the first try...got great hopes for the current one though. Now, I hear that if I just sign-on and participate in this thread there is a good chance I could get a "FREE VACATION". I sure do love all these great opportunities to win stuff.

No fair! You're already in South Florida!! You don't have far to go for a good vacation. :D I on the other hand, need to get away from here with the girlfriend. Okay, I think the electric supercharger cooled with an air to buttermilk intercooler is the best. :lol: :lol: :poke: :poke:

And let's not forget the fighter planes of ours during WWII that had supercharged engines.(called The P-38 "Lightnings") ;)

There...that oughtta get things going......

A supercharger (sometimes called a blower), a positive displacement or centrifugal pump, is a gas compressor used to pump air into the cylinders of an internal combustion engine. In gasoline engines this is the fuel/air mixture (the charge) when the fuel has been added. This increases the mass of oxygen, and of fuel, in the cylinder thus improving the volumetric efficiency of the engine making it more powerful. It is similar in purpose to the closely related turbocharger but differs in that the supercharger is powered by gearing, by belt- or by chain-drive from the engine's crankshaft while the turbocharger is powered by the mass-flow of exhaust gases driving a turbine. A supercharger may absorb a third of the total crankshaft power of the engine but still improve total output by 100 percent.

The supercharger is used as a power-boosting device in aircraft and cars, particularly for operation at altitude, although the turbocharger is more commonly used in both roles. Another use is in the Miller cycle engine that uses a supercharger to alter the normal four-stroke engine cycle to operate more efficiently.

[edit]
Basic concept
The amount of power a particular engine can produce depends on the amount of fuel and air that can enter the cylinder, the charge. With any internal combustion engine the only way to produce more power is to burn more fuel. To burn a given amount of fuel an exact amount of oxygen is required if the mixture is to be consumed without leaving excess fuel or oxygen behind. This chemically correct mixture is called stoichiometric and most engines have to operate at or near this chemically correct mixture for a variety of reasons.

The simplest way to produce more power is to build a larger engine with bigger cylinders, however this is not always practical for a variety of reasons. For, mainly, aviation use the main problem with increasing size is increasing weight out of proportion to the capacity. For automobile use the fuel consumption at all power settings increases with capacity.

Designers are left with a choice of supercharging or turbocharging.

[edit]
Automobiles
In cars the device is used to increase the "effective displacement" and volumetric efficiency of an engine, and is often referred to as a blower. By pushing the air into the cylinders, it's as if the engine had larger valves and cylinders, resulting in a "larger" engine that weighs less. Turbochargers are more commonly used in this role because they use otherwise "wasted" heat energy instead of using up power from the crank, but the supercharger reacts more quickly to power application and thus outaccelerates a car with the same amount of boost being provided by a turbo.

In 1900 Gottlieb Daimler (of Daimler-Benz / Daimler-Chrysler fame) became the first person to patent a forced-induction system for internal combustion engines. His first superchargers were based on a twin-rotor air-pump design first patented by American Francis Roots in 1860. This design is the basis for the modern Roots type supercharger.

It wasn't long after its invention before the supercharger was applied to custom racing cars, with the first supercharged production vehicles being built by Mercedes and Bentley in the 1920s. Since then superchargers (as well as turbochargers) have been widely applied to racing and production cars, although their complexity and cost has largely relegated the supercharger to the world of pricey performance cars.

Boosting has made something of a comeback in recent years due largely to the increased quality of the alloys and machining of modern engines. Boosting used to be an effective way to dramatically shorten an engine's life but, today, there is considerable overdesign possible with modern materials and boosting is no longer a serious reliability concern. For this reason boosting is commonly used in smaller cars, where the added weight of the supercharger is smaller than the weight of a larger engine delivering the same amount of power. This also results in better gas mileage, as mileage is often a function of the overall weight of the car and that is based, to some degree, on the weight of the engine.

There are three commonly used types used in today's automotive world: Roots type supercharger, and Eaton or twin-screw type supercharger, and Centrifugal type supercharger.

[MERCMAN]

The Roots type supercharger or Roots blower is a positive displacement type device that operates by pulling air through a pair of meshing lobes not dissimilar to a set of stretched gears. Air is trapped in pockets between the lobes and carried between the intake side to the exhaust. The supercharger is typically driven directly from the engine's crankshaft via a belt. In order for the Roots supercharger to deliver air at greater pressure than atmospheric, it must be geared so that it turns faster than the engine. It is named for the brothers Philander and Francis Roots, who first patented the basic design in 1860 as an air pump for use in blast furnaces and other industrial applications. In 1900, Gottlieb Daimler included a Roots-style supercharger in a patented engine design, making the Roots-type supercharger the oldest of the various designs now available.

Out of the three basic supercharger types the Roots is considered the least efficient. However, it is simple and widely used and thus is invariably the most cost efficient. It is also more effective than alternative superchargers at developing compression at low engine rpms, making it a popular choice for passenger automobile applications. Peak boost can be achieved by about 2000 rpm. Much work has been done to improve the efficiency of the Roots type supercharger, but because it does not have internal compression (the design can be classified as just a "blower") it will never have the same potential as the twin-screw type supercharger, or the centrifugal type supercharger.

All supercharger types benefit from the use of an intercooler to reduce heat produced during compression.

The Roots design is commonly used on two-stroke diesel engines, which require some form of forced induction since there is no intake stroke. In this application, the blower does not often provide significant compression and these engines are considered naturally aspirated; turbochargers are generally used when significant boost is needed.

[MERCMAN]

Centrifugal type supercharger
From Wikipedia, the free encyclopedia.
The centrifugal type supercharger is practically identical in operation to a turbocharger, with the exception that instead of exhaust gases driving an impeller, there is only a compressor housing, and that is driven from the crankshaft via a drive belt. As such the centrifugal exhibits the same benefits and down-sides. Boost increases with the square of RPM (unlike the linear nature of the positive displacement devices), however low-rpm boost suffers due to the fact that air can pass back through the supercharger with little restriction until RPMs rise sufficiently to counteract the effect. Of all the belt-driven supercharger types this type exhibits the highest efficiency, and due to its design and lack of low-down boost is often employed on near standard compression engines. The Roots type supercharger and the twin-screw type supercharger, however, produce low-rpm boost and as such feel far more reactive on the road.

All supercharger types benefit from the use of an intercooler to reduce heat produced during compression.

Twin-screw type supercharger
From Wikipedia, the free encyclopedia.
The twin-screw type supercharger is a positive displacement type device that operates by pulling air through a pair of meshing lobes not dissimilar to a set of stretched gears. Air is trapped in pockets between the lobes and carried between the intake side to the exhaust. The supercharger is typically driven directly from the engine's crankshaft via a belt. Unlike the Roots type supercharger, however, the twin-screw exhibits internal compression. As the air passes through the supercharger the air pocket decreases in size towards the outlet. This increases the thermal efficiency of the supercharger beyond that of the more available Roots style supercharger. In order for the supercharger to deliver air at greater pressure than atmospheric, the Roots supercharger must be geared so that it turns faster than the engine. Although the twin-screw type supercharger has more potential than the Roots type supercharger, its production costs due to close tolerances put it at a cost disadvantage. Also due to the internal compression the air exiting the supercharger exhaust "pops", this can lead to a whine noise or whistle (or scream!) that has to be tolerated or dealt with via noise suppression techniques. Although not as ultimately efficient as the centrifugal type supercharger, it does not suffer from the latter's lack of low-rpm boost.

All supercharger types benefit from the use of an intercooler to reduce heat produced during compression.

The VT Marauder WAS another option with the Paxton supercharger and it was the frist to do the bottom end.But two years ago nobody was doing there bottom end and the company went under.Now the car was up for sale for 27,000 and only7,000MI on the OD.I wish I had a crack at it.I bet with Lidios help that car could run low 12`s all day with the Paxton still on it plus your bottoms already done for when its time to put a shot in it.Just a thought.
