A few years ago they did this on another forum, they made graphs using proven power and torque figues only, all with the same capacity engine (5litre) but all other specs were totally random.

Only things taken in to account is boost and power/torque, but still came out with an interesting corrolation....





Power seems more sensitive to other changes, but torque follows boost bloody closely.


Maybe something similar should be done on here too, just out of interest? Obviously it will take someone to plot it all on a graph, and people to post up their numbers, but it would be interesting all the same.
