Any other positive displacement blower. Centrifugal type boost pressure increases with engine speed. They are however typically more efficient. They make decent top end as max pressure is achieved at or around redline; but lack bottom end torque because boost is low. Nature of the beast ...
Google types of sc and read some more. |

Regarding centrifugals - that used to be the stereotype of turbos too, but modern implementations don't have to be that way. You can size them for max boost at low speed and simply bypass when the limit is reached. |

A cent can have a bypass to bleed but then you are moving it out of its efficiency range as the rpm of the blower will eventually be too high. I thought you were seriously asking me a question. If you feel like you already know the answer than move on. Certain people actually want a cent. because the boost curve is linear. That's why we are reading this thread and not surprised at the lack of torque from a cent. We like its efficiency and n/a like power delivery. Did you read this excellent response? http://www.ft86club.com/forums/showp...2&postcount=27 My response was to projectd's question about instant power. In which he means torque. Adios. |

I did not. Re-read what I typed or look at boost and torque curves of different types of superchargers.
Torque is low on a cent. Therefore people looking for "instant power" should look at a roots or twin screw (positive displacement). |
