Issues I had last year

1st run - boost: 18 psi, timing: 24°/22°, O2s: .79

60' - 1.870
330 - 5.079
1/8 - 7.808
MPH - 90.26
1000 - 10.155
1/4 - 12.112
MPH - 115.80

MPH pickup: 25.54 (I knew it was going to be a good night)


Added boost and pulled fuel...

4th run - boost: 22 psi, timing: 24°/22°, O2s: .77

60' - 1.674
330 - 4.690
1/8 - 7.272
MPH - 95.61
1000 - 9.489
1/4 - 11.358
MPH - 120.62

MPH pickup: 25.01

Over the winter I did the following:
1) rewelded DS header
2) flow tested fuel pump and moved the hotwire to alt
3) got new alky pump from Julio (BIG DIFFERENCE)
4) new plugs
5) increased the trans psi

Not too bad for a 10 year old LU 12" 2800 convertor and stock MAF. :biggrin:
 
Good runs and good mph pickup up top. If you can get the 60fts down to the 1.5s (you should be able to at that power level) then you should be running 7.0s in the 1/8th and 11.1s in the 1/4. But maybe the tight converter is hurting you out of the hole? Still good times for that converter. Whats the full combo?

The converter is probably killing your 1st half of the track. You could probably add 5mph and get to mid 120s with a higher mid 10 slip. Not bad with that converter though, but you are leaving a lot on the table.
 
Agree I need a converter. The car pulled hard around the 1000' mark, I need to shift the 2-3 at 5500+. 2-3 shift were at 5000 on all the above runs.
