As much as I appreciate this blog piece, it is extremely pointless. A DynaPack and Mustang Dyno are two of the worst dynos out there. On top of that, you can't compare dynos from one dyno brand to another. This test would be infinitely more accurate if it were done on the very same dyno machine, that way all variable conditions would also be the same.

Woops, I meant to direct that at Edmunds. Not AutoBlog.

Heck, dyno 'numbers' in general are pretty pointless. Have just the dyno plots of a single car has some value, it shows the torque (and therefore horsepower) curves.
These tests are very interesting because they actually compare two cars on the same dyno. The 911 turbo is rated at 480ps and the GTR at roughly the same. Surprise surprise, they acutally point down the same power on the same dyno.
Interesting bits, even though the 911 has a smaller motor, its torque ramps up faster due to the VGT turbos. The GTR is superior from 3.5k to 6k rpms though, right in the meat of the rev range where you'd be spending your time on a road course.
LS2/LS7, two different UK mags have compared the GTR to a 911 turbo and GT3, and both times the GTR has been faster around the road course. Easier to drive and it puts down the power much better allowing for better corner exit speeds.

@why not the LS2/LS7?
"I bet the 911 turbo still takes it on the track. The bizarre rear engine 911 drivetrain layout has some significant advantages on the track"
Too general. Depends on what track. Reports so far suggests the GT-R is quite a bit faster with the GT3 being a closer match.

Can you please explain to me why Dynapack is a "bad dyno"?? From what I know, it is the most repeatable dyno out there because it removes a lot of variables of rolling drum dynos and newer Dynapacks come with software that very accurately accounts for the effect of the loss of the wheel/tire on horsepower.
