you mean your power to weight ratio, your not restoring horsepower.
so take your horsepower, divide by the weight of the car, if you increase your horsepower or lower your weight, the ratio gets better.
as for weight itself, in drag racing, the rule of thumb is every 100 pounds mean 1/10th or .1 of a second off your acceleration time. |

| 150lbs is a lot to remove. that' pretty much 1 passenger. it will make a noticeable difference for sure. there's no magic formula. |

I always thought it was .1 off of your 1/4mi time. Is that what you meant? |
