    that makes sense if the timing chart for ECT was pulling timing....250* is a lot of heat
    2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance
    2014 Xsport- 3.5 Eco boost
    412 Motorsports

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    I realize I'm really late on this but there is a lot left in the truck on current boost. A 1.8 60' is terrible, your mph is there. You get into the 1.4x 60' foot range and it should be high 10's no problem

    Yeah definetly a lot left in it. We will be turning the boost up to low 20psi range for the SAR meet. Hope to get some nice 10sec runs in.

    Love this thread. Does the small turbo feed into the big turbo or vice-versa like a diesel?

    Just like a diesel. Big turbo feeds the smaller one. This thing should be fired up tonight and maybe have a few test runs on Friday.
