Lightweight pulley kits
 

Yo.

Do lightweight pulley kits add horse power, or is money better spent on other things?

Matt.

I asked the question before. You r better with lightened flywheel, lightweight pulley has little effect but could cause some other issues (?cant remember exactly what issue they can cause)

I have a Kartboy lightened pulley and there is very little improvement that I've felt. The only difference I've personally felt is that the car pulls easier in high gears on low rpms.

If you can get yours for cheap, I'd say why not. I've not had any issues at all with it.
