simple - take out engine, strap to dyno, fire the bastard up.

then see who's telling porkies.

And you think people get up to some fiddling with chasis dynos, what makes you think engine dynos are any better?

All the same tricks still work on an an engine dyno, plus you have a climate controlled room that you can play with. How much more horsepower does it make if we lower the room temperature to say 5 degrees compared to a 30 degree day outside?

We are talking especially temperature sensitive turbo cars here, with intercoolers, oil coolers and large radiators. How much horsepower does it make if we lower the intercooler temperature to say -5 degrees, mix in enough cold water to lower the water temp in the heads to say 75 degrees and keep the oil at a nice 100 degrees?

Plenty of fun for everyone

Cheers

isn't that the whole point of DIN ratings for power outputs?

conditions are standardized for all engines??

Percentage loss through any drivetrain is flawed logic. Do a search to see why the argument is inane.

[joeyjoejoejuniorshabadoo]

why on earth is power at the engine relevent (esp when comparing it to another car)

the only thing that matters is how mcuh power ends up at the wheels

unless they have found some way for the engine to push it along the road directly.

maybe they have those guys are pretty smart

+ 1000000000

BUT

then what number would holden put on the back of their cars... 307 sounds a LOT better than the more realistic 230 or so............ i'm just surprised they dont use hp... (411 @ fw)
