The vette officially yours? That would be pretty darn nice.
With your mods.. you will be fighting traction even at the track. I'm thinking of the differences between our cars at the time I ran the conservative 13.185 1/4 mile. You should be able to pull off some mid 13'*, not sure if you can get enough bite on the pavement to do the low 13'* yet. We have serious traction issues. Do you have spring blockers or anything beyond the air struts in the back to help with weight transfer? If so, low 13'* should be close or attainable. If you can lauch better than I did and get some very cold air (40*F that night), you could pull into the high 12'*.
If I look at my time, all the mistakes I had on the tune, tire pressure, 60' etc etc, theoretically the car could have pulled a 12.8 that night. With the right conditions... I have a good feeling the SS IC gives you about the same or a little less cool air than a Gen V. It'* tough to say w/o testing them side by side.
When'* the track run?
all this talk has me jonesin...
