Its not an unfair contest as long you state proper comparative parameters.
I think a more accurate question should be asked, which powerplant produces the most cost efficient amount of HP per dollar.
Comparing powerplants is a fair and normal thing to do. How else do you decide an ideal powerplant for one's self and one's application? Its always about weighting in the pro's and con's. Don't be a hypocrite and condemn a harmless albeit unfocused question. It is this ignorance that keeps the Malaysian Autoscene single dimensional and shallow.
Just my 2 cents,
