calculating HP

[tonyk72]

Is there a way to calculate engine HP other than the tool on this website which uses 1/4 mile times? I'm looking for something in which you can plug in your engine components, etc and come up with a figure...something for free too. I know there are software packages that do this...I'm looking for something web based.
Thanks
