altitude and air temp hp correction?
anyone know how much hp is lost per 1000 ft or so eleation?
and a reasonably accurate idea of hp vs air temp. i've been told it's roughly 1% for every 10 degrees, but does anyone have a better idea? thanks |
SAE J1349

http://www.wahiduddin.net/calc/calc_hp_dp.htm There is also this one for force-inducted engines. I have only briefly looked at the calculations, but it seems like the guy has a good point. http://home.austin.rr.com/turbolexus..._Dyno_Calc.htm |
those are both great, but i don't have all the necessary info to plug in.
thanks for the help though, i'll make sure to pay attention to all those parameters next time. |

Sea level is 29.92 inches of mercury. Divide outside air pressure in inches of mercy by 29.92 and that should be about your hp loss.
