If you've got an idea of the horsepower that your putting out now, you can use the formula: (HP*.5)/(8*.8). This should give you a good ballpark figure.

Haven't looked up the formula, but I'm sure a search would verify if the formula given you is correct or not. That said, if you plan on going further than 400, then get the 36 lb. ones and have the appropriate chip burned.
