  • hope you Americans like the car we made for you. (This car is made in Australia just so u know its a Holden)

  • I'm ready for the G8's to start coming over. ;-)

  • i think i hear a supercharger.

  • You're hearing either gearbox whine, or the dyno roller.

  • I don't believe any of the numbers were made available to the public.

  • yea its easily over 500 HP. I believe its a ktec motor build might be able to find something out through them.

  • The GXP.R is nothing more then a reskined GTO.R and Outsightgto is correct.... they have a pretty much stock LS2 with a SMALLER then production cam because they dominated too much last year.

    gearbox is a sequential 5 speed manual standard for the series.

  • I love that car. That one of the few "real" GT cars in the Rolex Sports car Series, along with the Current Banner racing Pontiac GXP.Rs, and the Speedsouce Mazda RX-8s. Do you have more of these videos with even the daytona Prototypes as well? I would like to hear the Lexus Powerplant on the Dyno.

  • Yup, it sounds like a supercharger, but that's the gearbox whine.

  • It cant be supercharged, regulations disagree...

  • LS2 6.0L, Detuned to 380HP and 410 FTLBs as of July 2006. So preaty much like the off the street GTO without CATs. Only change from stock is race ignition mods and removeal of throttle by wire.
