can someone tell me how exactly a pully gives you more hp gains? got diagrams so i get the picture better?

 

No picture or diagrams needed. When you order performance under drive pulleys they do exactly what they say.........underdrive the accessories. The larger the accessory pulley, the slower it spins, reducing drag on your rotating assembly. The aftermarket pulley will be lighter, and larger, both reducing drag and rotating mass, this is a know physics control that will provide a slight, sometimes unnoticable power increase. I am not trying to talk you out of them, because a couple small power adders equals one large power adder.

 

Yeah, a total waste of $$$$. .1hp at the flywheel. Hold on tight! Not to mention your headlights always dim when you are at a stoplight, and if you have a sub you most likely will be going through a boat load of batteries.

 

dont forget to mention how they f*ck up the balancing on the crank. not worth it unless you have a race car IMO

 

well now i know.... coo thanx guys and/or gals
