I was going to use 15% as that is a much quoted figure, but I upped it to be very generous and try to approach the 260 to 300 hp quoted often by members here.
Otherwise we would have got (200 ÷ 85) x 100 = 235.3 hp at the crank which would have been very disappointing to some.

This figure is not even close to those numbers.

If you thought you had 290 at the crank then the hp on the dyno would be 232 to 246.5 hp. Not close again to the stated dyno numbers.
