I think the power some N2O cars put out is impressive, some not so much. Same with turbos and superchargers. One guy at work has a turbo 2.4 Mitsu Evo that puts out over 600 HP to the wheels on pump gas. Is that impressive? What it tells me is boost or nitrous or whatever power adder you want will overcome a lot of shortcommings with any engine. Not to say there isn't a lot of work involved there, it's just at a different level.

My son is going to build a turbo SB but I prefer to make horsepower the old fashioned way, NA. To each their own I say.
