Thread: 3 Degree Keyway

  1. #1

    3 Degree Keyway

    Got the HPS 3 degree in today. I know the Fernando keyway is cut differently, not sure if there is a significant difference in performance because of this. Anyone know the answer, or if they have the HPS, how does it perform?
    Thanks - PHISH

    hello phish, A 3 degree keyway is going to perform the same as another 3 degree keyway. If both are the same degree's.

    Jim, I saw "phish's" key way, it is only machined on one side!! how can it move the flywheel over without "slop" if it is only machined on one side?

    I say get on the phone with CARL ASAP.

    anyone installed a HPS yet??

    I hope so. I'm going to call island racing tomorrow and find out if it makes a difference in the cut. The way it seems right now is that there might be a little play in the HPS keyway after it's intalled.

    so if he doesnt slide it on just right, he could get anywhere from 1-3 degrees... I'm thinking I like Nandos better, no guess work..
