Looks like Kuwait has no problem reaching speeds with the VR 825 Kit

What was the boost on that ran?
Do you have a dyno with a baseline overlaid? I looked at the one on your site but it is lacking AFR and PSI, it shows 7.4 and .2 respectively?
What is the advantage of replacing the VTG turbos? Let alone billet cartridge VTG's? The GT3076 is susceptible to compressor surge where and the VTG's less so, and the efficiency map is inherently larger for VTG design . Aren't you also loosing the higher torque/boost pressure at low RPM's and inducing lag and possibility for boost creep?
Adding additional components such as boost controller, wastegates, fittings, lines, ect. just seems like the wrong direction. IMHO it seems like you would be taking a step backwards by removing VTG's, unless you are building a quarter mile car with a narrow power band.

The turbo is a GT3076rs with a .63ar. They are really not meant for torque but larger gains on the mid to upper RPM. Unlike a VTG turbo where HP and TQ are the same, Garrett does not produce the same outcome. The external wastegates and the 3.6L help with the torque, but you would see a 700tq/700hp type of dyno.
