This however, is one of the most innacurate ways possible to measure power output. Not that dyno output should be used to determine anything other then engine tuning. I'd not use a dyno sheet to brag about anything, it's about accurate as putting a blindfold on someone, spinning them around several times, and expecting them to throw a dart into the centre of a dart board they can't see.
When I go home, I'll get the links to all my information on this topic.
ok, so first you say that it is within a 4% tolerance (18% to 22%) and then you say its as accruate as spitting into the wind! Make up your mind. Fact is that 25% - 35% is considered acceptable loss by AUSTALIAN dyno shops using, in the most case, Dynodynamics. We are not in England or the US. As for it being the same world wide, thats crap anyhow. Its not the same from car to car or day to day. There are far too many factors in the real world. Things like exhaust, transmission, tyre pressure, temp, how tight the car is strapped down. There is just no way you can put up a set of numbers like 18% for manuals and 22% for autos. You mean to tell me an old XF 3 speed auto will have the same loss as a BA V8 4 speed auto? Get real. Forget the books Steffo, they are a guide only and usually full of personal bias etc. Go to a dyno shop, watch cars on the dyno, put yours on there and see what you can learn.
As for the drivetrain being on fire at 35%......I have no idea what you are talking about... thats just the most ignorant comment I've heard in ages.
