Arrow Unorthodox Pulley help

happy turkey day!

i got my car used, and the previous owner included some parts including spark plugs, brakes, and a unorthodox pulley. i don't know much about pulleys, so i'm asking for info about this one. i am wondering if its underdriven, and if it is, do i have to worry about charging and other electrical issues? and is this worthwhile to put on my car? the only thing i know about this is that it's made by unorthodox racing (it says so).

edit: also, if its underdriven, that means i would need new belts as well?

i included some pics of it:

What's the diameter of the pulley? measure the circumferance or get a rough diameter measurement.

Most likely, it's underdriven.

As for it being bad.....I wouldn't say it's bad....but it'd be better if you had a stock sized pulley.

Its going to destroy your car. Dont install it.




I am sorry if you believe that garbage like most people will tell you.


Ive been 'underdriven' for over 50k miles on an autocrossed RS and I have had NO problems so far.

Ill see if I can remember to see my belt sizes too, and post em up.

Take your stock belt to an auto parts store and have them give you a couple choices of each. Take them home and try them out. Keep the two that fit the best and take the rest back.
