by Rick! » Tue Apr 16, 2024 7:52 am For the OP, here's a screenshot from an ET Predictor based on Pat Hale's Performance Racing Atmosphere calculations. (a modified version of SAE J1349) I believe Larry's program uses Pat's CF calculations. I also use some formulas off of epi-eng.com for water vapo...
