408, 4L80, turbo H2

  Hey guys. This is my first post and I dont own a Hummer. We are doing one and I thought I share some pics of the mods we performed.
Its an '07 H2, 408, TFS 225 heads, 4L80, Vig stall, 246 transfer case, Victor Jr., electric fans, turbo charged, complete custom fuel system with twin Walbros.

 

 

 

 

 

nice setup...when are you getting it dynoed and how much you planning to make

Hope to be done in about a week. We still have some 4L80 stuff to work out.
We hope to make 700rwhp. Shouldnt be too difficult even with the drivetrain loss.

That's a lot of exhaust heat tape brud.  Nice job on the tight wrap, reminds me of a couple of my hockey sticks.

is he still going to get the same fuel economy with the turbo? Because I have been considering a suercharger or a turbocharger but trubochargers have some problems with lag
 

Looks real nice. What size turbo are you using?
I hope the owner dosen't go off road with that windmill down there
