I really believe that you have to consider a lot of things when
discussing this. All cars ar different. If you have the HP to take a car
225 MPH, I don't think getting there sooner is going to make it go
faster. I have recorded identical speeds in the last two miles when
running the roadster. I have also dropped down in rear end gear and gone
faster. The final gear is the most important consideration. Most of the
belly tanks and streamliners used to use one gear and slip the clutch to
get going. I still am not convinced that Bonneville needs to be a drag
race. Just my observations.
