    Update on 408 big turbo

    here's the original thread,
    http://www.ls1truck.com/forums/pics-...oker-88mm.html


    It's been upgraded to a 91mm ( i think) since then, customer worked the fuel system over and did a few other things.

    Here's the result:

    11.0 @ 120 in an extended cab.

    Hopefully with a little more practice, good traction and a good launch, it'll hit the 10's!

    later,
    allen

    I like. I need to trade Allen my complete nitrous kit for one of those "ugly front mount" turbo setups.
