Whenever a new performance car hits the market, a quick trip to the dyno always seems to be the first priority. This phenomenon again holds true for the new Pontiac G8 GT. After having driven the sport sedan, we remarked that the sedan's 6.0-liter small block V8 engine provided "a glorious combination of aural assault and potent propulsion." We do love us some alliteration! Getting back to the dyno, the good people over at PCMforless have already put their new G8 GT on a Dynojet for a few pulls. The first pull yielded 286.62 ponies and the second, after a bit of tuning, wrung the bell at 310.37 galloping horses. Factoring in drivetrain loss of about 15%, those numbers are (surprise!) right in line with the 361 horsepower that Pontiac is claiming for the G8 GT.
While over 300 horsepower is mighty impressive for a 30K-ish sport sedan, we'd be remiss if we didn't at least mention that the 2009 G8 GXP will be packing another 40 horsies underhood. Oh yeah... and a clutch. Check out a video of the full-pull after the jump, where you'll no doubt enjoy some of that glorious aural assault.
Thanks for the tip, Nick!
