A while back, in discussion on top end, in response to a question (David Borden?) I said I'd get back with the equation for HP vs. top end. Here goes - the shorthand version is that top end is a function of MPH squared. Without showing all the variables: for my car engine
HP = .01685 X MPH squared.
I do 140 mph with 330 engine HP. Someone asked how many HP extra to do another 30 MPH. I guessed 100 more, per the equation it'll actually take 155 more HP. If you know your HP and MPH, you can compute your factor (.01685) by: factor = HP/(MPH squared). It should be close the factor I have. If you need all the variables in the equation, let me know how to post special greek symbols in this forum and I'll follow up.
