    With an 8-tooth cog at 5500 it is 43, but then I can easily pull in OD to 48.
    With a 9-tooth cog at 5500 it is 48, but then I can pull in OD to 53 and beyond.
    Pulling a Comet belt too hard in OD will flip it over, but the Bando racing belt hangs tough.
    It will slip and glaze even a new Comet belt in just a few minutes.
    The thrill for me is repeated standing start WOT acceleration/deceleration to 5500-6000 in dirt/gravel or on blacktop.

    Did not know the belts had such a hard time at top speed. I kept my governor in my motor after I built it but can adjust it to 5K. Maybe I should leave it in. Got a torque converter for mine just have yet to install it. Maybe keeping it will save some belts.

    The beetle I had for years didn't have a passenger seat...
    If you rode with me you sat in the back..
    The TC provides gobs of torque at either 8/56 (7-1) or 9/56 (6.2-1) gearing.
    A blue and pink garter spring instead of two blues will bring the engagement down to 3000 rpm
    which works well too.

    At sustained high rpms i can imagine the belt is so hot it's becoming unglued..

    They only have a hard time when you try to apply well over twice the recommended hp
    and/or you try to pull past 5500 revs. Otherwise you will not have any issue at all with
    the belt.

    Please explain the belt having a hard time over 5500 rpm. I can understand the twice hp and it having a hard time under acceleration. Once the clutches are shifted out, then it is just engine rpm and the bike will in essence be direct drive as if you just had two fixed diameter pullies, as engine goes up 100 rpm, bike goes a little much faster. Another 100 rpm, faster again.
    I'm trying to understand more about the belt problems at higher rpm. I read similar comments in other threads.
    Perhaps others can learn also. Please explain in some detail.
    Thank you.

    Seems logical high torque could overdrive the tc making alot of slip causing heat especially if gearing is high...I'm just interested because is a puzzle that has an answer..
