Toyota began selling a bolt-on scion super charger kit for the 5.7-liter V8 Tundra during June 2008 xb. supercharger Powe rxb output is increased to 504 hp (376 kW) and 550 pound-feet (750 N•m) of torque. When the installation is carried out by a Toyota dealership the existing warranty remains intact.This kit features Eaton's Twin  Vortices Series supercharger xb which utilizes twin four-lobe rotors, a design shared with the newly introduced  and xb

MSRP for the kit is set at $5,875.

External compression supercharger refers to pumps that transfer air supercharger at ambient pressure supercharger xb into the engine. If the engine is running under boost conditions, the pressure in the intake supercharger manifold is higher than that coming from the xb supercharger supercharger supercharger.  xbThat causes a backflow from the engine into the supercharger until the two xb reach equilibrium. supercharger It is the backflow that actually compresses the incoming gas. This is a highly inefficient process, and the xb main factor in the lack of efficiency of roots superchargers when used at high xb boost levels. The lower the boost level the smaller is xb this loss, and roots blowers are very efficient at supercharger moving xb air at low pressure differentials, which is what supercharger they  xb were first supercharger invented for (hence the original term "blower").

Superchargers are further defined according to their method of drive (mechanical-or turbine).

Mechanical:

• Belt (V belt, Toothed belt, Flat belt)
• Direct drive
• Gear drive
• Chain drive

Exhaust gas turbines:

Boost is given in terms of pressure ratio, xb which is the ratio of absolute air pressure xb before the blower to the absolute air pressure after compression by the blower. If no boost is present, xb the pressure ratio will be 1.0 (meaning 1:1), as the xb outlet pressure equals the inlet pressure. Fifteen psi boost is marked for reference (slightly above a pressure ratio of 2.0 compared to atmospheric pressure). At 15 psi boost, roots blowers hover between 50% to 58%. Replacing a smaller blower with a larger blower moves the point to the left. In most cases, as the map shows, this will move it into higher efficiency areas on the left as the smaller blower likely will have been running fast on the right of the chart. Usually, using a larger blower and running it slower  xb to achieve the same boost will give an increase in compressor efficiency supercharger.
