Default underdrive pulley question??
what do they mean by 25% and 10% when it comes to the underdrive pulleys, you can choose either one and i dont know what the difference is.

25% underdrive of stock size. hence...it drives accessories at 75% of the stock rate....thats why you get a hp gain.

You won't get 25% more power. You will get back 25% of the power it takes to run the accessories.

Yep, all the accessories run at 75% (with 25% less rotational speed) of what they used to.
