T1 – 518 / T1 – 518hd

The predecessor of the T1-518 was installed in the Alpina Supercharger V8 (530HP) until 2011. The vehicles B5, B6 and B7 are legendary in terms of performance and efficiency.


The ASA T1-518 in its hd variant can cover higher speeds. The supercharger unit is even more precisely balanced and uses selected components such as hybrid bearings with outer-/ inner steel rings and ceramic ball berings, resulting in smaller centrifugal forces and higher bearing stiffness.
