Gt-r Dynoed: 475hp At All Four Wheels!

If this is true then it might explain why the car is doing so well despite its hefty weight.

With 15% drivetrain loss were looking at around 550hp!

I wouldn't trust a Japanese run Dynopack as far as I could throw it. Check out Giant's thread on how much their GTR made on a Japanese Dynopack, like 100 hp more than on a DynoDynamics here. The lack of wheels on the hub dyno makes a bit of a difference, 20 hp or so, but not 100.

Dyno Dynamics dynos DO read silly low though, even compared to most other rolling road dynos. Giants result seems really high for a dynapack though - assuming he is the dude running N1s? Theoretically there isn't a huge amount you can do to make them read real high, you can see the TCF is set to 1.00 which is the main place you can inflate figures.

can't dyno's work out flywheel kw? Motor tested some Holdens and Fords a few months ago on a dyno dynamics dyno, and that worked out fwkw to like 3% (for most cars) of the manifactures clames. 475 hp is awfully close to what is on the specs sheet.
