My honest guess was 12.9's. I was wrong. 13.13. 60ft stayed the same 1.86. Lost 1st round of trophy by 500th of a second. Had some difficulties.... Rain delay, car was lean and I got it to quit snapping by moving the acc pump cam to #2, not sure it isn't pulling vacuum from between ports or something.

This is been my point with you for years now and it's finally coming to roost. 16 down to 13 ain't the same as 13 down to 10... From 16 to 13 you can add some headers and another part here or take a little weight off there and get a noticeable gain. The 13 to 10 cost money and gets a lot harder.. I assume 13.13 was your best time slip, what were your others?
