    Escalade twinTurbo

    Hmmm...actually it took longer than I expected. The engine is running well now)
    During the process the concept has changed from twin supercharged(twin Vortech V2 blowers) to twinTurbo application. Two superchargers on one belt was not the right decision in the beginning. Belt is burning actually in action. So if somebody will decide to built that, need to use short tooth belt instead of rib one.
    So in the end we have 416ci twinturbo engine and the list of parts installed looks impressive )

    Block
    LSX short block (GM Performance Parts)
    Lunati crankshaft (416ci)
    Lunati rods
    Wiseco pistons
    ATI damper
    Clevite bearings
    ARP lugs and nuts

    Heads
    CompCams camshaft .588/.588
    Ferrea valves
    Lunati valve springs
    CompCams trunnion kit
    CompCams pushrods
    Rollers GM Performance
    Cometics gaskets
    ARP lugs and nuts
    TrickFlow timing chain set
    Durabond bearings
    Melling high performance oil pump
    NGK spark plugs
    MSD wires

    Fuel system
    2*BOSCH 044 fuel pumps
    Automotive Industries fuel pump brackets
    Holley fuel rails
    AEM pressure control
    Injector Dynamics 1000cc fuel injectors
    Aeromotive secondary fuel pump 400lph

    Intake
    Twin turbo Garrett GTX35 1.03 A/R VBand
    Wastegates TIAL 44mm VBand
    BLow off valves TIAL 50mm VBand
    Holley EFI intake
    Water to Air intercooler(custom)

    Exhaust
    Custom headers
    Corsa muffler
    SW 2*mufflers

    Suspension
    Arnott/Bilstein struts
    DJM bars
    Eibach springs 2" drop
    PU bushings

    Brake system
    Superbrakes 6/4
    DBA rotors 410mm
    Ferodo DS2500

    Here is the first engine start made monthes ago: http://youtu.be/ye5CqiQb2FM

    Today the engine works with lightly modified transmission, so waiting for the new transmission built.
    Also I've ordered new 3.73 axle gears instead of 3.42 stock size and new ls differential lock. So...will see, it should have even better dynamic with the current tranny

    No, it is custom made. Potentially it is more powerful than the one from Hennessy, so will see how will it goes in autumn with the new tranny
