I was finally able to make it to the track to try out the new setup. I was disappointed in the ET's and 60 but at least she was consistent.

I was able to run down in the quarter finals before being put out by a Ahole cheating with a delaybox.

The new set up is a spooled 4.88 rear gear in a moser 9" housing. And 28 X 10.50 ET drags.

60' consistent 1.65 to 1.67
1/8 mile consistent 7.65 with a best pass of 7.59
and MPH was consistently 90.XX

The car slowed down in MPH, ET and 60' from previous runs on old setup:
10 bolt 3.73 on 26" ET drags. Times in sig reflect old setup.

I was surprised that I lost 60'. I was expecting to pick up a .10 or .20

However I was pleased with the consistency...

Is it normal to lose that much MPH from drivetrain loss of the 9"?
Why would my 60' decrease?
The times seem to consistent to have been spinning any...

I'm gonna guess and say that is way too much gear for the current setup
