21 Turbo damper pulley + adjustable camshaft pulley

Alu Damper Pulley + Adjustable Camshaft Pulley Pack

The damper pulley:

The modified design of this pulley was created in 2010 by Mespiecesauto in order to achieve a real weight saving, positioned as far off-centre as possible.
The original pulley weighs around 2100 grams and the aluminium pulley 785 grams, i.e. 1.3 kg less.
This weight saving has a multiplier effect given the angular acceleration of the pulley. The faster the pulley accelerates, the greater the weight-saving benefit, a bit like the famous G-force.
