Best Weather to Dyno? Does anyone know (on a dynojet) What is the best temperature, humidity etc to dyno a car?
I know the dynojet corrects for different temperatures, but what is the best temperature for optimium dyno performance? Post up if you really know the answer

It shouldn't really matter, the Dyno should measure all the atmospheric conditions, and give a Corrected HP#, that is the Standard. Any other way would mean all the Dynoing across the world would mean nothing except to you. If you want to see big numbers, low level, low temp, and high humidity.
(raining) The extra moisture in the air will help the combustion and cool the intake charge as it travels through the intake trac. A la Water injection.
A 350 cube engine @ 600 RPM with high humidity will injext about 150 cc of water/min.

humidity hinders power production..the space the water is takin up is less fuel/air mixture for combustion, water injetcion is only for ultra high heat/high pressure situations where the offset would be more detriminal than helpful...best power production days would be cold, dry day with a high DA

So the temp diffenrence doesn't matter? I know dyno jet is SAE corrected, but whne I dynoed my SS druing the summer the temp was like 95.3 degrees. will there be any difference when I dyno it when the temp is like 45 degrees?

High humidity will rob you more than the dyno typically will correct for. You want to dyno on low humidity days for best results. High barometer also helps. The dyno seems to correct better for temps than it does humidty and barometric pressure.
