Anyone see anything I may be doing wrong by these times? I have the car in D the whole way. It's a 305 w/ 2.73's, relatively stock. The SFC's and LCA's aren't installed yet. I'm not having a problem with traction, and I've tried flashing the convertor, stalling to 1300 and 1800.....

Run....60'....1/8..MPH.....1/4....MPH
0....2.280...9.863..69.63...15.302...86.63<~my only run before tonight @ SLP Day
1....2.304...9.845..73.56...15.222...92.40
2....2.284...9.853..73.22...15.242...92.06
3....2.327...9.905..73.25...15.254...92.57
4....2.327...9.891..73.00...15.260...92.49

 

Try leaving off an idle and see if that helps.

Break the run down to see how the car runs at different parts of the track. All 5 passes have poor traction from the looks of those 60' times.

Now ignore the 60 foot times and break down the rest of the run. I'll just use the last run as an example.

60' time = 2.327
The time it took to go from 60' to 1/8 mile was 7.564 seconds.
The time it took to go from the 1/8 mile to the 1/4 mile was 5.369 seconds.

By breaking down each run you can see where the car gained or lost time. Anything can affect the times. Torque through gear shifting should all be done in the first 1/8 mile. If the shift point isn't the same each time, then the time can change. Many other variables can affect this. The last 1/8 mile should be a brute HP pull. Weather conditions are the biggest changes in this time. Anything from a change in wind direction to the amount of moisture in the air can change how much HP the engine has to move the car.

The more incrementel time the track gives you, the better. Most tracks should be giving 60', 330', 660', 1000' and 1320'. The more you can break down a run, the better you can understand what's happening on each.

Ignoring your first pass, your car is making consistant hp with 92.x mph runs. It's slowing down a little in ET each pass. That could just be because the oil in the transmission is getting too hot. Your passes are close enough that you could dial it in for a bracket race and probably win.

 

The car's not spinning at all, it's bogging down. I did try leaving off an idle, it still bogs down.

The first run was on a completely different day bye the way. All the others were the same night at the track.

 

The car feels crappy below 23--...after that it pulls hard.

 

thats still some respectible times for a 305 auto with 2.73's.

 

that is pretty good, my camaro with the stock 305 only runs mid-16's.

 

3760 lbs with a full tank....I was at about 1/4 tank for the runs.
