I know mine was 259@wheels, 297 crank, on low boost, but it's 2wd, I'd expect 4wd to be between 25 to 30%, some are nearer 35 though.
Simple way to find out is get it on the rollers that can actualy measure precisely the trans loss in coast down test, you'll have exact firgures of wheels and flywheel then.
