I ran a 13.87 at 101.8 in 2067 ft and 98.0 % relative density. last january when i ran the truck before cam and blower, just bolt ons, i got my best time of 14.79 at 91, but it was -1237 ft. should i be running alot better if the DA drops like that again? thank you

 

The lower the DA (density altitude), the better your truck will perform. The "D" im DA refers to the desnsity of oxygen in the air. Ideally you want low temperature, low humidity and high barometric pressue.

-So yes..the lower the DA the faster you go (All other things same)

 

DA is just the theoretical altitude based on the temp and pressure at the given time. Its just a way to easily convert a temp and pressure to a unit that is more recognizable.

 

thanks guys, yeah i didnt know how to calculate it to a -1250, i dont think the calculator would do it.

 

Use this link. Choose your track and the date, then choose the weather at the time, it i will calculate it for you
