    Harmonic balancer for LS2???

    Is the harmonic balancer for the Corvette ls2 the same as the CTS-V ls2?
    and or does anybody have the OEM part number for cross referance?
    Need to order one ASAP, and summit can't verify.
    Mine desided to seperate, and the outter shell startet moving forward, took out both my belts and chewed up my wire to the MAF sensor while it was at it. Good times.

    I got mine through Thomas at Hendrix engineering for 6 bills. He will be able to tell you exactly what you need. It was at my front door in about one week, also. So far, so good. It went on about 6 weeks ago and produced a measured 9.3 lbs boost with the Maggie 112. Interesting side note. I ordered my Maggie from Hendrix and a friend ordered straight from Magnuson. We had them side by side and you could tell just from observation that these were not the same machines. One of the techs at the dyno shop I ended up at told me "you have a Magnuson supercharger that was a special order built to Lingenfelter specs." We have different sizes and brands of injectors, and lots of other subtle differencess. Is one better or worse? Who knows! Our dyno numbers were almost identical. But I would call Tom on your balancer. Mine is Innovators West and measures 8" across. Beautiful piece of machine work, sat as my"centerpiece" for a month!

    My online research indicates that both the 2006 CTS-V and 2005 Corvette LS2s use GM Part Number 12635652, which supercedes the orignal GM Part number 12583637.

    Thanks darkman.
    The Innovate west is a sure nice piece, but out of my budget right now.
    I was going to go with the ATI, but there would be a delay in shipping, so I went with summits brand.
    I'm sure anything is an upgrade from the OEM.
