Tire shake in rear engine dragster - lost .02 in 60' .04 in 330 4.35 / 6.80 dragster
Spraying 300HP dry about 1 second before finish line.
Shock sensors & wing: Shows right side compressing 1/4" while left extends 1/4" at launch. At 2 seconds into the run the wing is creating enough down force to start compressing both sides. At the finish line (206MPH) compression is 1 1/4" (probably bottoming shocks)
Right front wheel sensor on my dragster showing double wheelstand and .5 before settling down.
Oil perssure drop from 80 to 35 5 seconds into the run
all 8 EGT's dropping 100 degrees
showing high intake air temps - 297* peak! October 2010 run.
RP overlay of two runs. The car was .08 slower in second qualifying run.
Logs show first 2.5 seconds almost identical (a little more spin on slow run
accounting for .01-.02). Then at 2.48 seconds boost actually drops 1 lb when
it should have been building. Then a 2-3 lb difference the rest of the run.
After seeing the boost issue from the overlay, went over blower clamps,
hoses etc and discovered a AN-10 plug we use for priming the motor was
missing. Put a new plug in and the car went right back to 6.68 @ 205.
RP log showing
.2 or so delay from the time the MSD triggered the air shifter with 12 volts
to the time RPM's started going down.

Greg's procharger car taking .7 after the leave to
ramp up to 6000 converter stall which requires about 12 lbs of
FAST log from JR Baxter showing typical flat acceleration line off
starting line. Note that JR says car will static stall @ 6600 and you
can see that it drops to 6150 after the shift.
Shows shift signal holding ON for complete run. Drops
voltage 2 volts. Changed shift trigger and fixed inconsistency.
