i see alot of people here, and on other sites, mostly american, gettin rather antsy about the Dyno test on TG
along the lines of "duh its not gonna have 500bhp at the wheels, wheel dynos only measure power at the wheels, engine is still 500bhp blah blah blah"
and to that i say this
its not beyond the engineers of this world to easily work out/back calc to get a good idea of power at the fly wheel. some use arbritary % to guesstimate and others can actually work out power at the flywheel by letting the car coast to a stop with the clutch pressed in.
you have losses from the gearbox, rolling resistance is alittle higher due to how the wheels sit on the machine, etc.... these can easily be accounted for.
granted its not as accurate as an engine dyno, but its not going to be too far off the mark.
so my question to you all : why do people think TG and the dyno guys would omit a very easy task like that?
out of spite?
