There is no simple formula to use because 1/4 mile times depends on a lot more variables than wheel weight alone. If you know what the other variables are then you could try to isolate the impact from wheel weight, but this not a simple process. In the end you would have done a lot of work for a very "rough" calculation.
The easiest and probably most accurate process would be to make several runs with both setups and compare the times.
