Any good websites for adjusting et/mph from DA?
I'm just now learning a little about Density Altitude correction. And I was wondering if anyone could recommend a good racing related website where I could put in all my information and get a rough correction. Or compare what I could run between two different DA's with the same setup.
It's kinda got me thinking lately because I ran a 12.011 N/A in ~2900 DA. And I'd like to see how a lower number could ideally affect it.
Thanks

I estimate that every 1000ft takes off about 1.5 tenths...
To convert your timeslip ET and MPH to sea level. Multiply applicable factor times your ET or MPH.
(Example: You ran a 14.4 @ 103 MPH at 5000' elevation track. The correction factors are .9367 and 1.0661 for 5000'. (14.4 * .9367) = 13.50 , (103 * 1.0661) = 109.80 MPH. So the correct timeslip would be 13.50 @ 109.80 MPH at sea level)
