well i cant really answer that because i dont know what components are really included in the itsturbo.net turbo other than the front mount intercooler. but then again, were talking about contours here and that 19" intercooler wont fit on the contour. so theyll have to up the price and get a water/air IC like the street flight kit or just forget about it completely. if they threw in a water/air IC like street flight, i think the price will be a lot closer to SF. but considering the non svt made 265 fwhp and the itsturbo.net made 245 fwhp, i would say that the street flight kit would make more power on an svt. but lots of factors such as boost pressure, gas octane, how aggressively its tuned, etc can only determine really which kit is better. personally, i think the price difference is worth the more quality components that street flight sells.
