While the initial OPs question is of course valid and interesting, I would like to introduce a thought about the OPs goal of "300 HP". This is of course not a "problem" only here, but overall. By wanting just a nice number for not a particular reason other then "I have 300 HP bro" is so wrong on so many levels. But lets say our brain is playing tricks and just want a nice number. How about this? Horsepower is a retarded ancient unit same as inches and so, why not to opt for civilised target of 200 kW? 200 kW is very nice number as well, is a normalised unit and is 268 HP. You have a nice number, on better units and you can keep you internals and money significantly more save.
How about that?
