i'm curious if you know at what temperature the g's power numbers are rated, i work with the sae corrections often, and made myself a calculator, "how much power will i make today?"

this weather is pretty much standard temp (70degrees), but some correct to 60degrees instead, and it's about a 4hp difference, but it's basically when the car is at it's "nominal power".

My sheet may not be as accurate as a dynoshop's, but it still gives a pretty good idea of how much you actually loose due to high heat and humidity (and conversely gain in the winter when it's cold and dry)

by my numbers, when it's -25deg celcius with minimal humidity, a 2003 sedan is making 300hp (:

while at 35deg celcius, and 85% humidity, it's less than 250...

yeah, it's a rough approximation, but pretty cool none the less...

Curious, has anyone done a non-corrected dyno pull at -25? just to see if these SAE folks know what they're talking about?
