ever used the "Virtual Engine Dyno" ?

I had never heard of it before so I went and checked it out.
I have to say that is a pretty cool progam, it just has a bunch of automotive related equations all put together in one tool, pretty handy.
As far as being accurate all those equations are standard and fairly simple so it should be pretty accurate. I tested a few of the equations and they are ok.
Great find, thanks.
