Road Horse Power
Earlier I posted my HP table and the formatting was all screwed up in the process. The relevant data from my HP posting is for the 80 MPH and 85 MPH data which I will now summarize.
At 80 MPH the truck naked gets 15.1 MPG which translates to 64.2 RHP.
At 80 MPH with aero appliances 18.2 MPG which translates to 53.3 RHP.
This means it took 10.9 less HP to do 80 MPH with the aero appliances added.
At 85 MPH the truck naked gets 13.2 MPG which translates to 78.1 RHP.
At 85 MPH with aero appliances 16.2 MPG which translates to 63.6 RHP.
This means it took 14.5 less HP to do 85 MPH with the aero appliances added.
The truck naked requires 53.5 HP to do 75 MPH v 53.3 HP to do 80 MPH/aero.
The truck naked requires 64.2 HP to do 80 MPH v 63.6 HP to 85 MPH/aero.
This is an 17% and a 18% improvement at speeds respectively with aero.
