First step to increase low-end torque?

[Steve Tinker]

I spoke to Jake Raby a few years ago regarding Flat6's underdrive pulley. He says that the pulley was good for 10hp above the standard item and after fitting mine I would tend to agree.
The improvement is felt in the lower to mid range revs, just were we drive most. Its not a difficult or expensive replacement and after 3 years of operation I still believe its the best cost effective mod I've invested in.....
