temperature of 70 degrees Fahrenheit. Once you know the correct stock
jetting for your particular Holley carb, you can determine whether you
live or race at an altitude above sea level. For every 2000 foot
increase in altitude, you can reduce the jet size by one size. If you
had a carb which has a stock jet size of 80 and you live or race at
2000 feet above sea level, then you would use a #79 Holley jet in the
carb. Similarly, a change in the carb's inlet air temperature may
require a change in the jet size from the stock calibration. Many
racers go a step further by combining all of the weather varibles,
temperature, barometric pressure, dewpoint and humidity with the
altitude of the track they are racing at to determine the "density
altitude". This is a "corrected" altitude above sea level. From there
they can determine whether a jet change is necessary to maintain
performance or whether to change their "dial in" (if they are bracket
drag racers). <br clear="none"></div><div dir="ltr" id="yiv6191531145yui_3_16_0_1_1439384791588_157438">-----</div><div dir="ltr" id="yiv6191531145yui_3_16_0_1_1439572148815_9366"><br clear="none"></div><div dir="ltr" id="yiv6191531145yui_3_16_0_1_1439384791588_157439">So assuming you don't care if you run lean at sea level, your optimal jet size for 6000 ft is likely 3 sizes smaller than optimal at sea level.
