Both are cool, N/A or supercharged. What I take from this is 700 forced induction HP will be easier to live with, better on fuel etc. Not saying that 700 N/A HP can't drive long distances or on the street regularly (ThumperDart and sixpackgut both proved it), but again a forced induction engine will do it a lot better, likely less maintenance and likely be faster with a compromised (streetable) set up. Look at Dizusters Savoy, 9 sec whip that idles like it's almost stock! No crazy gears of convertor needed
