Racepak Info Interesting Logs

2-1-11 showing hit intake air temps - 297* peak! October 2010 run.

9-29-10 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.

9-23-10 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.

5-5-10 RP log showing 12 volt event wire on trans brake

10-27-09 RP log showing Greg's procharger car taking .7 after the leave to ramp up to 6000 converter stall which requires about 12 lbs of boost.

5-14-06 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.

10-05 Shows shift signal holding ON for complete run. Drops voltage 2 volts. Changed shift trigger and fixed inconsistency.

Mark's 4 link dragster shock travel about 1/2" extension and not much else ex

Hard tail dragster skipping the tires (Paul's car @ cecil county right lane)

10-10-04 Fuel pressure dropping from 60 PSI to mid 40's when Nitrous activated when using Enderle 0 fuel pump.

5-17-2003 Greg's car - still using Rupert Carb - shows Vacuum pump @ 7.8 during run and 13 after I lift. (Moroso 3-vane with MSI relief valve) - not yet using the the 66% pulley
