This is something I have fitted to a number of racing engines in the past and the dyno showed almost nothing.

Looks nice but I think you would get more bang for the buck but fitting a less restrictive air filter system.

The main crank pulley on these isnt raelly that heavy anyway. Youd get way more MPG with conservative driving habbits but what fun is that?! :D
