Most racers use an air density gauge. This gauge
is fairly inexpensive. It basically establishes
C.R.A.D. for you by combining the variables on any
given day.
First, establish a base line main jet by testing.
After you have determined the correct main jet,
record the jet number and the air density gauge
reading.
Example: Base line
Gauge reading 90
Main jet 300
The next day at the track, your air density gauge
now reads 105. This means you have gained 15%
air density.
New density 105
Base line 90
105 – 90 = 15
Multiply your base line main jet by 115.
Example: 300 x 115 = 345
Round off to next highest jet size.
New main jet = 350
Air density can change rapidly during the course
of the day. Check your gauge frequently. Always
use the same gauge for a different gauge may
read differently.
