can someone make a java app that has the Y axis = time and the X axis = HP and the constant is the average weight of a 1200/210/310?
then you can just figure out what 1/4 time you want and you'll know how many HP you need. then maybe another line that shows how much it costs to have the a series make that much HP.

it's like a dyno chart.

or try this...
