Based on this 100 degree to 90 degree (10 degree differential) holding air pressure at 31 and relative humidity at 30% for both shows 102.2% and 104% respectively - translating to .18% hp differential per degree.

If this is true, for a motor of 350 hp, per 10 degree drop of intake air should result in 6 hp gain roughly.

That's the general factor we use for 'Intake Air'.
