How does alt. effect E.T.

[EPCobra]

I am at 3500 ft and I was wondering how much it effects my E.T. from sea level. I recently hooked up a dry 100hp shot of nitrous and I ran 13.77 @ 111.01mph. I was hoping for more but I wanted to figure in for the altitude. Thanks.

thanks, it makes me feel a little better. It converted to a 13.1 at 116 with full pressured tires launching on a highway.
