Does anyone know where I can find a web sight that has corrections for altitude.

I don't know of a website but if you want a scan of NHRA's Altitude Correction Factors for Stock & Super Stock, e-mail me.

Your 14.14 @ 96.7 mph corrected for 2300 feet (the chart is in 100 foot increments) is:

13.76 @ 99.44 mph

 

The Calgary Drag Racing site has the NHRA Stock/Super Stock conversion chart.

I do my corrections using the same formulas as a dyno to give proper altitude HP based on density altitude and power to weight ratio.
