I don't know how relevant it is, but I will throw it out there, because I am bored.
I have not been able to find efficiency charts like that for the eforce, but it is a 2300 TVS rotor assembly so it cant be far off in numbers.
My LS402 makes 724 hp @ 12 lbs. Compression is 9.9 to 1. There is more in it but the tune is not super aggressive.
Hope that helps.
