Need A Little help Please

The other aspect not being discussed is....... the combo seems to be underachieving.

410 with W2’s should easily be in the 575-600hp range.

If the motor were making the power, and the car running the proper speed in the 1/8...... the 4.56’s might be fine.

Using these inputs:
575hp
2800lbs
350ft track elevation
70deg
50% humidity
29.70 observed baro
