There are formulas to calculate BHP
There is a simple formula to calculate BHP: BHP = 2 times pi times torque times revolutions; all this divided by 550. Pi is 3.1416 and torque is in pounds-feet, and revolutions are revs per second. Here's another version: P = 2 time pi times torque times rpm times 1.34 times 10 to minus third power. Divide the results by 60. For this formula P is in horsepower and torque is in Nm Formula is taken from : http://pweb.jps.net/~snowbum/hpcalc.htm |

uhh ... does the formula include friction , heat , air mass , fuel injected , air fuel ratio and ton of other thing that can cause loss in hp ?
well if there is no contributing lost to hp , then yes the formula is right anyway , no need to strain your brain or whatever lah , just go dyno machine easiest , lol |

Of course Dyno is the 1 but here is the algorithm ofrmula to it so yes, there are formulas to calculate HP so your post saying that there is no calculation for HP is total wrong
if you add friction lah, heat lah, air mass lah, fuel injected lah.....that 1 is not formula already.....thats more towards test and trial This post has been edited by shinjite: May 28 2006, 04:06 PM |

Bore is the diameter for the Piston .. and stroke is the distance it travel from highest point to the lowest point. |

Flywheel about 130+hp, so after about 20% loss should be almost 120+hp like that at max.
