    I think Vortech rate them at about 65000rpm ???

    At least, thats what they rate the YSi I am using.

    Ive spun mine closer to 68500 in 4th gear crossing the line with an 8.5"/3.0" pulley combo on my LS1.

    right now I have a 8 and 3 and likely around a 6500rpm shift. I do not care what pulleys or cogs how hard can I spin it.
