Well I went to cecil county raceway this saturday since it was going to be my last chance to race for the year... I managed to get 8 runs in all. A couple things to take into consideration. Previous bests were in 70-80 degree weather at a diffrent track, temps this day were in the 40's. I was smoking the clutch during the runs was getting worse as the day wore on. All shifts were made at 5800 RPM by the stock tach except the last run which all shifts were done@ 6000 rpm by the stocker.
Run 1
27* initial by the balancer /stock fuel pressure.
60 ft= 2.155 (street tires at 30psi)
1/8th ET = 9.302
1/8th MPH = 79.54
1/4 ET = 14.150
1/4 MPH =102.77 (This was worse than my previous best MPH 103.7)
Run 2 (back up run)
27* initial by the balancer /stock fuel pressure.
60 ft= 2.274
1/8th ET = 9.651
1/8th MPH = 77.88
1/4 ET = 14.56
1/4 MPH =101.42 (trans wouldn't go into second gear)
Run 3
27* initial by the balancer /1 full turn on the regulator
(Don't know the FP forgot my gauge)
60 ft= 2.241
1/8th ET = 8.926
1/8th MPH = 82.60
1/4 ET = 13.695
1/4 MPH =104.15 (better than previous best)
Run 4
27* initial by the balancer /same FP as previous run.
60 ft= 2.093
1/8th ET = 8.794
1/8th MPH = 82.56
1/4 ET = 13.539
1/4 MPH =104.68
Run 5
32* initial by the balancer /took out a 1/4 turn of FP.
60 ft= 2.081
1/8th ET = 8.717
1/8th MPH = 82.72
1/4 ET = 13.48
1/4 MPH =104.07
Run 6
34* initial by the balancer /same FP as previous run.
60 ft= 2.104
1/8th ET = 8.833
1/8th MPH = 82.24
1/4 ET = 13.614
1/4 MPH =104.14
Run 7
27* initial by the balancer /Took fp back up by a 1/4 turn.
60 ft= 2.116
1/8th ET = 8.805
1/8th MPH = 83.04
1/4 ET = 13.552
1/4 MPH =104.64
Run 8
27* initial by the balancer /same FP as previous
60 ft= 1.944
1/8th ET = 8.532
1/8th MPH = 83.48
1/4 ET = 13.247 BEST TO DATE ET
1/4 MPH =105.16 BEST TO DATE MPH
2 things I want to address...
First thing is that the EEC doesn't seem to be advancing the timing as it should. The timing diffrence between the spout in or out is maybe 7*, does this sound correct?
Second, the MPH still seems to be low but I know with more practice & a more accurate tach I should be able to squeeze out a bit more. Even if I can get another 2 mph out of it I would have figured on closer to 110mph
Thanks for any help!
