So Christmas is coming and one of the things i want to get is a Pulley.
Which one should i go for to give me some extra power.

The only thing is is that i dont want a lightweight crank pulley because of the long term damage and i have a system in my car so i cant get a pulley thats gonna suck up my electrical power.

Is there another type of pulley i can get to add some power?

 

there is no such thing...you either lighten the pulley or make it smaller, that is the only way to get any power from it. And in your case an underdrive pulley is not an option so either you go with the possibilty that the lightweight one will eff up your motor...which i have yet to see and its making me want one...or just scrap the idea
