HOW IT WORKS

WHIPPLE TWIN-SCREW OPERATING PRINCIPLES
Inlet Phase – The male and female rotors rotate counter to each other. As the lobes of each rotor travel past each inlet port, air is trapped between consecutive lobes and the cylindrical casing. The air moves axially (forward) throughout the case and fill the inner-lobe space between adjacent lobes.

Compression Phase – As the rotors mesh, the air is trapped between the rotors and the casing. Continued rotation progressively reduces the space occupied by the air causing compression.

Discharge Phase – Compression continues until the inner-lobe space becomes exposed to the outlet port, through which the air is discharged into the manifold.

The compression sequence continues on all rotor segments simultaneously. Timing gears synchronize the rotors. The rotors do not touch the casing or each other thus assuring long life, consistent performance and low parasitic losses.

HOW IT WORKS: THE CONCEPT OF SUPERCHARGING
Supercharging of internal combustion engines has been used for many years as a method to improve engine performance and efficiency. Entering the millennium, a new trend is appearing. The trend points to small displacement engines in order to meet federal emission legislation on fuel consumption and emission control. The driver, however, still demands the same performance they're used to.

A good way to meet these needs is supercharging otherwise known as forced induction. The purpose of supercharging an engine is to raise the density of the air charge, before it's delivered to the cylinders. Thus, the increased mass of air trapped and then compressed in each cylinder during each induction and compression stroke makes more oxygen available for combustion than the conventional method of drawing the fresh air charge into the cylinder (naturally aspirated). Consequently, more air and fuel per cycle will be forced into the cylinder, and this can be efficiently burnt during the combustion process to raise the engine power output to higher than would otherwise be possible.

Generally, there are three basic types of "superchargers," the most popular being the exhaust-gas driven turbocharger, mechanically driven superchargers and the pressure-wave supercharger. The mechanically driven supercharger is broken up into two groups as well, the mechanically driven centrifugal supercharger and the mechanically-driven positive displacement supercharger such as the screw-type and roots-type

In automotive and marine applications, the pressure-wave supercharger is rarely used. The turbo and roots-type superchargers have been the most popular forced induction methods in the past. While the turbo creates great peak horsepower, turbo lag and high cold start emissions due to the thermal mass are severe drawbacks of the turbocharger. Small displacement engines need higher-pressure ratios to achieve the performance demanded by the driver. This fact increases the mentioned drawbacks of the turbo and makes the turbocharger a less desirable alternative for supercharging than the mechanical twin-screw supercharger. The Whipple twin-screw charger does not have the usual drawbacks of earlier mechanical superchargers such as the roots-type, such as poor efficiency especially at high-pressure ratios, high rpm, high noise level as well as high price. Comparative tests, made independently by Whipple Industries, show that the twin-screw compressor is the most effective supercharging method available.

SUPERIOR ENGINEERING
Our relentless commitment to creating products that exceed the cutting edge of design, performance and quality has given us the reputation as innovators and leaders in the high performance industry.

Every Whipple product goes through extensive research and development to ensure proper operation in all applications. Our standard development practice involves the measurement of over 100 parameters utilizing our own custom designed data acquisition computers. Measurements include individual cylinder air/fuel ratio from a true wide range Horiba sensor, individual cylinder pressure and cylinder combustion analysis as well as solid-state exhaust gas temperature. Our expert calibration team has over 15 years of OEM experience calibrating the most stringent emission standards such as Super Ultra Low Emission Vehicles (SULEV) and Zero Emission Vehicles (PZEV). No other supercharger company has a more advanced staff in computer technology and emission friendly products. Every product gets extensive R&D time on either our DynoJet Chassis dyno, our Superflow engine dyno or our Land & Sea propshaft dyno. This ensures that you get maximum power from our product and long, trouble free operation.
