Yes, I was sleeping at the light! Just wanted to practice launching:D

Turned rear suspension to the hardest and front to the softest for weight transfer.
Ran the 245/50/16 Nitto NT01 tires @ 15 psi and still could only get a 1.9 60ft without spinning.
Expected a little better times. The only difference from the dyno to the track is changing out my 7.40 pushrods to 7.35. I had to shift into 5th gear towards the end with the 25.6" tall tires and 4.10 rear end. A heat soaked IAT probably caused some timing to be pulled as well.
I think my tach was off a tad. I should be able to hit 127mph with my setup and a 6800 redline.
Probably won't go back to the track for a long time. I just wanted to run it once to see how it would do. More of a road racing and auto-x guy.
