Aftermarket forced induction = custom base classing, same as last year, as explained in the classing document http://www.nasaproracing.com/rules/nasa-x_classes.pdf (see section 1.5). So the regular points sheet doesn't fully apply to you. If nothing has changed on the car since last year, you don't need to submit a new dyno form. Didn't we decide your new base class was D with 0 points? That means you take points for anything else you've done to the car - suspension, etc - anything but power. More than 19 points and you go to C. Pretty sure A6's will bump you to C
