There is not a snowballs chance hell that you can hit mid 14's with 5.5 psi on that tiny snail in your overweight hatch. OKAY OKAY, you can hit mid 14's on slicks. It's better to underestimate than to over estimate. First time I wen to the track, I said I would be happy with a 15.5, ended up giving up after hitting 15.2. I beat my goal, made me happy. I knew it would run a hell of alot faster than 15.5, but I didn't want to go home disappointed, so I set a low goal.
