.3 by homemade ram air, smog pump delete and a battery in the back ???

so you dropped from 13.8 to 13.5...???

did you 60' change as well? i'm guessing the added traction by the battery in back is what helped your times out the most

I picked up a total of 3 tenths by unplugging the alternator, and lock up converter switch.

Just unplug the alternator before i race??? Does this make it spin easier?

as for .3 tenths it was when my car was in the low 14's a few years ago. I when from consistant 14.40's to consistant 14.10's.
It was on the same track 2 weeks apart in similar weather conditions. I was pulling 2.10's in the 60 ft mark. the times were the same . the battery relocate i just did.
That was before i invested in a g-tech, i do runs now on the same day on the same road, and average a few runs to be more precise.
