probably a stupid question but why does ford claim 300hp ?
Just curious. But is it an American thing to think manufactures claimed BHP figures are at the wheels??
It's not adig, but I see it all the time on US forums, but never non-American forums.
Manufactures have ALWAYS claimed the output at the engine, at least since before the First World War, so it always suprises me why so many think it's at the wheels, lol.
As for the 05, well 300bhp SAE Net is probably bang on for the engine. Howver you will probably see claims from 250-280rwhp.
This is because some dyno's achieve readings in different ways, also there are correction factors for temp/humidity/altitude/and others, plus spike smoothing on the graph. And the addition of different stands such as STD or SAE.
All in all I would expect 250-260rwhp to be a REALISTIC value, anything higher is most probably due to a variation in HOW the numbers where acheived, however it won't actually mean it's anymore powerful or faster.
So take ALL rwhp numbers with a pinch of salt, as they are anything but accurate.
