for hub power figures add 17.5hp for each hub connected to the dyno to get the flywheel figure.
if its a tyre roller you are on dyno dynamics for instance does estimated flywheel figures which add more due to wheel and tyre friction losses, I think dyno dynamics adds 17.5% to rwd wheel figures to get
the flywheel figure, 4wd something like 22%.
this is where the problems come and ive mentioned this a few times on various forums, when people add for instance dyno dynamics corrections to hub figures the figures are huge and simply
far to high.
made r32 made 415 at the rear hubs so 450 hp crank and that is with the stock afms absolutely flat out and there rated to 450 hp max so not far out.
