Charles, this is how you determine flywheel horsepower: Rear wheel
horsepower divided in 0.8.
you can do it the other way to, flywheel HP times ( * ) 0.8 = rearwheel HP
My truck with only 1200 miles on it would have 189.2 / 0.8 = 236.5 HP @
flywheel. Then it depens on how well the dyno is setup and calculated, I'm
not to unhappy with those figures. I did notice a big different in power @
about 3000 miles so you can't expect a brand new engine will deliver full
power from 0 miles.
