Part works great, after some modification....
Posted by Chris on 11th Jun 2017
After doing some research on various performance lightweight pulleys available for the FRS, the pulleys offered by Top Speed offer the greatest weight reduction and the lowest price when compared to other more popular brands. After a good experience on a previous purchase (catlless mid pipe and over pipe) I was happy to give this part a shot.
I went to install the part today and the crankshaft pulley did not fit. There are two holes in the pulley, the center hole and a keyhole, and the keyhole was not bored wide enough. I had to spend time slowly opening up the hole with a drill to help it finally slide on. It's still snug, but atleast I am not having to jam it on.
I was pretty disappointed when thinking that I was going to have to reinstall that stock pulley and use the new crank bolt that I had to purchase for the install (it gets torqued to yield and so cannot be re-used, meaning I would have to buy yet another one for any future installation attempt: $9 + $10 shipping).
I decided to see if I would have any luck widening the hole - it worked, and I am very happy with the results. Best bang for the buck upgrade I have installed. Feels like atleast a 10 horsepower upgrade for just $100 ($80 for the pulleys + $20 for the replacement factory crankshaft pulley bolt)
