    Default Magnuson 04 CTS-V vs Nitrous 09 G8 GT

    My friend just got his car back on the road after he ate a piston and had to rebuild the motor so we decided to line them up and see where the chips fell.

    2004 CTS-V - M6, stock displacement 9.8:1 forged motor, LS9 cam, stock LS6 heads, 1.9 liter Magnuson blower, full exhaust

    476 rwhp, 460 rwtq

    2009 G8 GT - A6, bolt-ons, full exhaust, 150 shot, drag radials

    486 rwhp, 561 rwtq

    2009 G8 GT - cam, bolt-ons

    Your car moves pretty damn good man. I'm really really really liking the idea of a little spray for the G8...

    Nice run man. That 04-V moves pretty well.

    BTW, what axle-back do you have on the car right now? Running Solos or the stockers?

    Thanks for the comments! He's thrilled to have his V back on the road and banging gears again.

    I currently have the Solo Performance axle back on the car. I might try the GXP setup down the road. The Solo's seem to be worth between zero and two hp on the dyno with this setup.
