I know that this question probably varies by vehicle, but is there a set formula to figure out CHP to WHP (and vice versa)? I see ALOT of WHP numbers from dynos and I would like to know if you can convert that back to CHP (for comparisons). I have heard different percentages from 10 - 20 loss from CHP to WHP. I would think that a stick and automatic would have different equations (sticks having less of a loss). Any thoughts/input would be appreciated!!
