Regarding the RAM inlet I have no idea, doesn't sound and look too smart! The intake/filter is NOT as good as most well mounted cones!
Regrading hood scoops, if the scoop was in the front corner of the hood it would work. Up in the middle (symetric, retro?) ontop of the engine it and the tubing gets too hot. On a dyno with the hood closed and a big a$$ commercial fan blowing full boost the air temp came down 1.5 centigrades, for 1 RWHP, could be a meassuring error. I'm sure at speed it's better... Or a Cobra ram air in the front... or two, one on each side... or a cooled SC should ram enough cold, dens air for most... :winks
