Just ordered an Unorthodox Racing stock diameter crank pulley! According to them, this will shed 7 lbs. of rotating mass off of the front of the car resulting in quicker revs, better throttle response, and more freed up horsepower. They are also claiming gains of 10-14 horsepower, but I am assuming that is at the crank, not at the wheels. We'll find out soon enough!
PM me for pricing and availability!
