    Probably who-ever is willing to cough up $15k for an ECU, custom exhaust manifold, air bypass plumbing, and a tuner to fly in and get it running.

    The suby manifolds along with the rest of the plumbing necessary could be sourced through here : http://subaruwrcspares.com/11.html

    I believe the correct PN's are :
    CS-14008Z0H73 Exhaust Manifold WRC Inconel S10 with Rocket
    CS-14008Z0HR6 Exhaust Manifold WRC Inconel S11 with Rocket
    CS-14008Z0H58 (S12/K0/006-C) Exhaust Manifold WRC Inconel S12/S12b with Rocket
    CS-14008Z0HV1 (S12/K0/106) Exhaust Manifold WRC Inconel S12c/S14 with Rocket

    ALS Valve
    #S12BJ910 ALS Valve Assembly
    #S12Q1025-1 ALS Motor

    Not sure of costs though, prices aren't listed in their excel price list : http://subaruwrcspares.com/resources/WRC$27spares_8.xls

    Could use the suby manifold rocket as a basis for designing one for other setups, or just duplicate the rocket itself.

    Also....who says that the "extra" fuel being injected through the engine ever sees a spark? (You should see the "randomizer" table with Pectel's ignition for torque reduction.)

    I wouldn't count out fuel being randomly injected through a sequence of cylinders and spark being cut to those cylinders for 1 cycle.
    Make sense?
    The one in the vid is a 2ltr engine, guessing at least 140CFM to start the process and hit the target turbine speed, since he revs it up to 5k. No idea how much more the turbo contributes to that, plus when and how the ALS valve is opened. One could probably get away with a bit less if you just want the process just to self sustain though.

    I can definitely see it done exactly as how you described, but wouldn't we hear uneveness in the exhaust tone from the cutouts?

    Some eye candy here : http://www.subaru-msm.com/2012race/sgt/engine.html

    The 2011 and 2012 BRZ in the GT300 run pretty much the same system.
