In Reply to: Sebring vs. BEGI for 1.9 posted by Phat Z on April 02, 1999 at 15:49:54:
The BEGI unit is an AutoRotor supercharger and the Sebring is an Eaton "roots" type supercharger. The AutoRotor is a bit more thermaly efficant (produces less heat) than the roots type.
The BEGI includes an intercooler and puts out more boost. As a result you get a bit more HP and more torque than the Sebring unit.
It also costs a lot more.
Robert had some nice graphs to show this, check the archives.
Other than that I have had my BEGI for about a year now with no complaints. I track the car regularly with no problems so far...
