race 850 is 6k instead of 5800, thats about the only performance difference. Most of the other differences deal with the crash boxes and ecu programing for them.

If you use 65GPH for the 850 and if the 1075 has about the same efficiency, then it would be about 82GPH. Not sure how real world GPH numbers compare, but they are probably close.
The HP/12 is just a general rule thumb.
