That's the sort of idea I had. 
If the Gower power reading is sampled at every 250rpm from the torque curve between peak lbft and HP then we can work from to get the reading in hp using the 5252 rule.
I would be good to get all dyno sw to work out these number instantly
Not a bad idea that! It gives a more realistic view of the flexibility and true performance of the car. I think it may need a little tweaking though as some cars like the K04 can have fairly late peak torque and early power peak, whereas a K03 can have a very early torque peak and a high power peak depending on mods.
I'd say the reasonable sample would be 2.5krpm to 6.5krpm, that way the useful rev range is covered and any anomalies at the lower and upper parts of the rev range are eliminated. 17 samples in all. This could be further tweaked for big turbo applications where the rev range is higher and 19 or 21 or 23 samples could be taken. This way it would also reflect not just on the power, but the flexibility of the car and how fast it is in the real world. Any good?
