Vehicle Engine Horsepower

 

Vehicle Engine Horsepower Formula
\( EHP_v \;=\;   W \cdot  \left( \dfrac{ s }{ 234 } \right)^3  \)
 Units English Metric
\( EHP_v \) = vertical engine horsepower \(lbf-ft\;/\;sec\) \(J\;/\;s\)
\( W \) = vehical weight \(lbf\) \(N\)
\( s \) = speed \(ft\;/\;sec\) \(m\;/\;s\)

Vehicle Engine Horsepower Formula
\( EHP_{vc} \;=\; W \cdot \left( \dfrac{ s_2 }{ 234 } \right)^3 - \left(  \dfrac{ s_1 }{ 234 } \right)^3  \)
 Units English Metric
\(\large{ EHP_{vc} }\) = change in horsepower \(lbf-ft\;/\;sec\) \(J\;/\;s\)
\(\large{ W }\) = vehical weight \(lbf\) \(N\)
\(\large{ s_2 }\) = final speed \(ft\;/\;sec\) \(m\;/\;s\)
\(\large{ s_1 }\) = initial speed \(ft\;/\;sec\) \(m\;/\;s\)
